Hello NFC Community! This document demonstrates that multiple records can be also read from a Tag with TagXplorer. Please follow the steps below. Let's begin... Please make sure that you have written more than on record with NXP TagWriter app. For a more detailed explanation on this, please refer to the following document: Writing multiple NDEF text records with TagWrite app  The app can be found and downloaded from the Play Store: NFC TagWriter by NXP - Apps on Google Play  -> Connect the reader in TagXplorer -> Place the card on the reader and press Connect Tag -> Check for NDEF (1) and then, read NDEF (2). The Text Records can be visualized in the NDEF Payload Info below: I hope this is of great help! Ivan R.

Recently, some NFC customer want to use CCID driver to communcate with NFC reader on Linux platform, but they encontered some errors during installing CCID driver for linux. I tested it and installed it to ubuntu 16.04 LTS successfully. Let me share complete steps with those users who want to devevlope NFC applications based on linux platform. If we want to use CCID driver on linux, we need to install these packages: --libusb --pcsc-lite --ccid driver --opensc Before starting to install above packages, probably we need to install necessary dependency packages: # sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev # sudo apt-get install x11proto-core-dev libx11-dev lib32readline-gplv2-dev lib32z1-dev # sudo apt-get install libgl1-mesa-dev mingw32 tofrodos python-markdown libxml2-utils xsltproc uuid-dev:i386 liblzo2-dev:i386 # sudo apt-get install gcc-multilib g++-multilib # sudo apt-get install subversion # sudo apt-get install openssh-server openssh-client # sudo apt-get install libudev-dev # sudo apt-get install openssl  # sudo apt-get install libssl-dev 1. libus installation (1) Download it from : libusb File name is libusb-1.0.9.tar.bz2 (2)Decompressing it # tar jxvf libusb-1.0.9.tar.bz2 # cd ~/ccid/libusb-1.0.9 # ./configure # make # sudo make install (3) test it # lsusb 2. pcsc-lite installation (1) Downloading pcsc-lite package: MUSCLE  Filename is : pcsc-lite-1.8.22.tar.bz2  (2) Decompressing it # tar jxvf pcsc-lite-1.8.22.tar.bz2  (3) compiling it # cd pcsc-lite-1.8.22 # ./configure # make ... # sudo make install ... 3. CCID driver installation (1) Downloading it from : Alioth: Muscle PCSC lite: Project Filelist  file name is : ccid-1.4.27.tar.bz2 (2) Decompressing it # tar jxvf ccid-1.4.27.tar.bz2 (3) Compiling it # cd ccid-1.4.27 # ./configure After runing configure command, information below will be displayed: ... # make ... # sudo make install ... 4. opensc installation (1) Downloading it from : OpenSC - Browse /OpenSC/opensc-0.16.0 at SourceForge.net  File name is : opensc-0.16.0.tar.gz (2) Decompressing it # tar zxvf cd opensc-0.16.0.tar.gz (3)Compiling it # cd opensc-0.16.0 # ./configure --enable-openssl --enable-pcsc # make # sudo make install Up to now, above 4 software packages have been installed to ubuntu 16.04 LTS. (4) Add library file path    open /etc/ld.so.conf , and add one line at the end of the file :  include /usr/local/lib , save and exit, run 'sudo ldconfig -v' to update it. # sudo gedit /etc/ld.so.conf  # sudo sudo ldconfig -v 5. Add Vendor ID & Product ID to info.plist We should add Vendor ID & Product ID of NFC reader to info.plist, the file is at the path : /usr/local/lib/pcsc/drivers/ifd-ccid.bundle/Contents/. For example , PN7462's vendor ID is 0x1FC9, and product ID is 0x0117. [Note] This requires Firmware on NFC reader board should support USB CCID, if not, customer should replace it with firmware that supports USB CCID, for the purpose, customer can refer to UM10915.pdf(http://www.nxp.com/docs/en/user-guide/UM10915.pdf ) to do it.

When the PNEV5180B cannot work with the Cockpit, you can re-program the firmware to the board. Below are the steps show you how to program the firmware to the board again. 1. If you don't have the MCUXpresso, please download the MCUXpresso from the NXP web first. MCUXpresso Software and Tools for ARM® Cortex®-M cores|NXP  2. Install the MCUXpresso IDE v10.0.0 to your PC. 3. Configure PNEV5180 board to use external power supply J101, and then power up the board. There is 10-pin ARM Cortex header on the PNEV5180B , connect  LPC-Link2 debug probe to it (J7) by using flat cable and also connect debug probe to the PC host over USB mini cable - both jumper on debug probe are open (JP1 and JP2). 4. Start MCUXpresso IDE and import any LPC1769 project from filesystem. For example: SW3522.zip. This is important to give programmer right definitions. SW3522 can be downloaded from here : NFC Reader Library v4.040.05.011646 R1 for PNEV5180B including all software examples  5. After import the SW3522, you can try to build the example and run the example on your board. e.g. NfcrdlibEx1_BasicDiscoveryLoop. Click LinkServer GUI Flash programmer icon on the main menu. When started programmer tool will check if LPC-Link2 debug probe is attached. 6. Browse to the C:\nxp\NxpNfcCockpit_v4.0.0.0\firmware\Secondary_PN5180\BootLoader_And_Nfcrdlib_SimplifiedAPI_EMVCo_Secondary.bin. Set the Base address to 0x0. 7. Flash Write Done. 8. After this, reset the board and to start NFCCockpit v4.0.0.0. The board will be recognized. P.S. The board is connected to PC via VCOM. If there is any driver issue, please try to re-install the VCOM driver and restart the PC. The VCOM driver can be found in the C:\nxp\NxpNfcCockpit_v4.0.0.0\VCOM.

This post contains step by step guide of how to use NTAG 5 with LPC55S69. The goal of this post is to enable developers to use NTAG 5 and LPC55S69 together, quickly and easily.    Attached with this post are two ready to use packages:      'Simple_NDEF’ demonstrates how to read/write to NTAG 5 from the I 2 C  interface and field detection functionality.      'Passthrough’ demonstrates SRAM passthrough functionality, in which NTAG 5 acts as a fast bridge between the I 2 C interface device and RF interface device. NTAG 5 Overview NTAG 5 is a family of ISO/IEC 15693 and NFC Forum Type 5 Tag compliant tags with an EEPROM, SRAM, and I 2 C  host and slave interface. This ensures information exchange with all NFC Forum Devices with a tap. With this ability, the tag offers a long-reading range and privacy due to close proximity with mobile devices. NXP’s NTAG 5 boost shrinks the NFC footprint while adding AES security, so designers can deliver ultra-compact devices for use in IoT, consumer, and industrial applications. It is an NFC Forum-compliant contactless tag that delivers exceptional read range, giving tiny devices the ability to interact with the cloud, and other NFC-enabled devices, including smartphones. NXP’s NTAG 5 link lets designers of sensor-equipped systems add an NFC interface with a wired host interface that’s configurable as an I 2 C master/slave, a Pulse Width Modulator (PWM), or a General-Purpose I/O (GPIO). Operating at 13.56 MHz, it is an NFC Forum-compliant contactless tag that can be read and written by an NFC-enabled device at close range and by an ISO/IEC 15693-enabled industrial reader over a longer range. Hardware Requirements NTAG 5 Evaluation Board (OM23510ARD)                         OM23510ARD                                     2. LPCXpresso55S69 Board Hardware Connections Connecting the two boards is very easy since both have Arduino compatible headers, so simply plug the NTAG 5 EVK board on top of the LPCXpresso55S69 board.   1.

Hello NFC community, The purpose of this document is to show the steps to port the Bluetooth pairing example for NTAG I²C Plus from KW41Z to KW36.  Setup For this, we will work with following boards: 1. Arduino NTAG I²C plus board (OM23221ARD) development kit. 2. KW36 Freedom board.  Download SDK as mentioned in chapter 2.1.3 of KW41Z User Manual and pay close attention to include NTAG I²C middleware. Now, repeat the same procedure above for FRDM KW36, this will be the SDK on which we will be making the modifications for the porting. NOTE: Unlike KW41Z, for KW36 there is no NTAG I²C plus middleware as shown in the image below: Save changes and build the SDK. NTAG I²C middleware will have to be imported from KW41Z's SDK in MCUXPresso. Install the SDK and import hid _device freertos example into the workspace: Copy ntag_i2c_plus_1.0.0 folder from KW41Z workspace to KW36's Open folder properties and uncheck Exclude resources from build, then apply and close. In board.c file add the following code below BOARD_DCDCInit()  /* Init DCDC module */ BOARD_DCDCInit(); #ifdef NTAG_I2C /* Init I2C pins for NTAG communication */ BOARD_InitI2C(); #endif // NTAG_I2C‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ In AppIMain.c add the following code in main_task before calling App_Thread()  #ifdef NTAG_I2C /* Initialize I2C for NTAG communication */ HAL_I2C_InitDevice(HAL_I2C_INIT_DEFAULT, I2C_MASTER_CLK_SRC, NTAG_I2C_MASTER_BASEADDR); SystemCoreClockUpdate(); /* Initialize the NTAG I2C components */ ntag_handle = NFC_InitDevice((NTAG_ID_T)0, NTAG_I2C_MASTER_BASEADDR); // HAL_ISR_RegisterCallback((ISR_SOURCE_T)0, ISR_LEVEL_LO, NULL, NULL); #endif // NTAG_I2C‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ In ApplMain.c add the following under Public memory declarations /************************************************************************************ ************************************************************************************* * Public memory declarations ************************************************************************************* ************************************************************************************/ ... #ifdef NTAG_I2C NFC_HANDLE_T ntag_handle; // NTAG handle #endif // NTAG_I2C‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Include new headers to the following: In ApplMain.c include the following  #ifdef NTAG_I2C /* NTAG middleware module */ #include "HAL_I2C_driver.h" //#include "HAL_I2C_kinetis_fsl.h" #include <app_ntag.h> #endif //NTAG_I2C‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ In hid_device.c include the following #ifdef NTAG_I2C /* NTAG handler */ #include <app_ntag.h> #endif // NTAG_I2C‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Copy app_ntag.c and app_ntag.h files from KW41Z  workspace to KW36's. The app_ntag.c source file contains sample functions for working with NDEF messages. Function NFC_MsgWrite() creates and writes the NDEF message in the Type-2 Tag format to the NTAG I2C chip through the ntag_i2c_plus middleware. The write algorithm is NFC-Forum compliance. Function NDEF_Pairing_Write() contains a procedure to create a BTSSP record via using the NDEF library. The same is performing function NDEF_Demo_Write() function. Here is shown how to create NDEF multi-record that contains several types of NDEF records. The app_ntag.h header file contains predefined blocks of constants (constant fields of data) that are written to the NTAG I2C chip by default during the communication which requires set the default content to the chip’s registers or erase the NTAG I2C chip user memory and registers of lock bytes. NOTE: Please change the I²C Master base address and I²C Master clock source from I2C1 to I2C0 as below in app_ntag.h: In hid_device.c make the implementation in BleApp_HandleKeys() as below.

In this file following parameter must be changed gSecurityMode_1_Level_3_c to the new parameter: gSecurityMode_1_Level_1_c Parameter gSecurityMode_1_Level_3_c is used on several places within the app_config.c file. Use the FIND function (short key is “CTRL+F”) of the IDE to find it and update. There are last two parameters of the gPairingParameters structure which are necessary to change. parameter: .securityModeAndLevel = gSecurityMode_1_Level_3_c, has to be changed to: .securityModeAndLevel = gSecurityMode_1_Level_1_c, parameter: .localIoCapabilities = gIoDisplayOnly_c, has to be changed to: .localIoCapabilities = gIoNone_c, parameter .leSecureConnectionSupported = TRUE, has to be changed to: .leSecureConnectionSupported = FALSE, Symbols Add the following symbols to project settings -> Preprocessor. The ones in red are for integration of ntag_i2c_plus middleware and the one in green is for adding the NDEF library, please see below: Include paths Please add the following includes in project settings. The ones in red are for NTAG I²C Plus middleware and the ones in green for the NDEF Library, please see below: With the previous setup it shall be able to run Bluetooth pairing example as for FRDM-KW41Z. Hope this  helps!

The latest NFC reader library for CLRC663 just supports LPCXpresso1769 and FRDM-K82 boards, so when customers want to porting the library to other host controller, they have to make a custom board at first, or use OM26630FDK and make a little hardware modification by following the steps described in https://www.nxp.com/docs/en/training-reference-material/NFC-READER-K64F.pdf?fsrch=1&sr=3&pageNum=1 to connect the frontend board with host controller board, but today we will discuss an alternative way. The CLEV663B Blueboard is a pure NFC frontend board, and it supports connecting with LPCXpresso board not limited with LPC1769, the main difference with OM26630FDK is the reader IC, which is CLRC663 not CLRC663 plus, but fortunately they are pin to pin compatible, so we may replace it with CLRC663 plus, and use that board for porting purpose. Before: After: please forgive my poor soldering skill... With this new board and LPC1769 Xpresso board, you may run the latest 5.12 NFC reader library, for example, the NfcrdlibEx1_BasicDiscoveryLoop demo. but you might have the following issue: This is due to ver 5.12 use another set of IO pins to connect with the reader IC, modify pin definitions in Board_Lpc1769Rc663.h can fix this issue. The final result is as below: Please note, it is recommended using NFC reader library ver 4.03 to test the hardware including CLEV663B and LPC1769Xpresso before replacing with CLRC663 plus, and you know, CLEV663B Blueboard is just optimized for CLRC663 , so the matching circuit is not the best for CLRC663 plus, it is just good enough to run the demo, so that we may know if the porting is successful, but if you want to have the best performance with CLRC663 plus, you have to redo the antenna tuning, and you may refer to https://community.nxp.com/docs/DOC-335545 for more details on that topic.

This post contains a step by step guide of how to use PN7150 with LPC55S69.  This document is structured as follows: Overview of PN7150:  The PN7150 is a Plug-and-Play all-in-one NFC solution for easy integration into any OS environment like Linux and Android, reducing Bill of Material (BoM) size and cost. The embedded Arm® Cortex®-M0 microcontroller core is loaded with the integrated firmware, simplifying the implementation as all the NFC real-time constraints, protocols and the device discovery (polling loop) are processed internally. In few NCI commands, the host SW can configure the PN7150 to notify for card or peer detection and start communicating with them. It has the following salient features: Full NFC forum compliancy with small form factor antenna Embedded NFC firmware providing all NFC protocols as pre-integrated feature Direct connection to the main host or microcontroller, by I2C-bus physical and NCI protocol Ultra-low power consumption in polling loop mode Highly efficient integrated power management unit (PMU) allowing direct supply from a Battery Overview of LPC55S69:  The LPCXpresso55S69 development board provides the ideal platform for evaluation of and development with the LPC55S6x MCU based on the Arm® Cortex®-M33 architecture. The board includes a high performance onboard debug probe, audio subsystem and accelerometer, with several options for adding off-the-shelf add-on boards for networking, sensors, displays and other interfaces. The LPCXpresso55S69 is fully supported by the MCUXpresso suite of tools, which provides device drivers, middleware and examples to allow rapid development, plus configuration tools and an optional free IDE. MCUXpresso software is compatible with tools from popular tool vendors such as Arm and IAR, and the LPCXpresso55S69 may also be used with the popular debug probes available from SEGGER and P&E Micro. Hardware requirements: OM5578/PN7150ARD  LPCXpresso55S69 + usb  micro cable  Using PN7150 with LPC55S69-EVK: Hardware Connections: The hardware connections are simple. Both the LPC55S69-EVK board and OM5578/PN7150ARD board have an Arduino interface. So, mount the PN7150ARD board with male Arduino connector onto the female Arduino connector of the LPC55S69-EVK board. Running the demo: If this is the first time you’re using LPC55S69-EVK board, follow the getting started guide first à  LPC55S69-EVK | NXP . Make sure to install the SDK package for LPC55S69-EVKboard which is required for the project below to run. Download the ‘NXP-NCI_PN7150_LPC55xx_example’ package which you will find attached to this post. Drag and drop the downloaded package to the “Project Explorer” tab of your MCUXpresso IDE workspace (If you don’t have MCUXpresso, it can be downloaded for free by clicking here: Now that the package has been imported to the MCUXpresso IDE (via drag and drop), click on Debug icon from the Quickstart panel to begin a debug session. Once the debug session has started, click on the run icon to run the code: The project should be running now. The project contains basic discovery loop functionality. Here is how the output looks in the console tab on MCUXpresso: Bring any NFC card near the PN7150 board’s antenna and the output console will show the detection and type of the card. For example, in the picture below, we can see that type 4 card was detected: Available Resources: AN11990 NXP-NCI MCUXpresso example document.

This porting guide is for FRDM-K82F, and it can also be used for any other platform supported by KSDK 2.2. The released NXPNCI-KDS_Example_KSDK2.2 is based on FRDM-K64F, so before porting, we need to configure and download KSDK 2.2 for FRDM-K82F. Please make sure you have selected Kinetis Design Studio before downloading. After downloading, extract the package to some folder like below: and change PROJECT_KSDK_PATH to this folder: Change project settings as below: Remove all files in the folder of drivers, and import new source files as below: and similar procedure for "startup" folder and "utilities" folder: Replace the source files in board folder with the files from some ksdk demo like hello_world: FRDM-K82F uses PTC3 for NCI_IRQ pin, PTC9 for NCI_VEN pin, and PTA1 and PTA2(I2C3) as the I2C interface. so add definition in board.c and modify BOARD_InitPins() as below: Change linker settings: -Build -Debug settings -Test Result:

The demonstration aims at how to protect the NDEF messages in the NTAG, here we use OM5569-NT322ER | NTAG I2C plus Explorer Kit + reader | NXP  as this dev kit contains NTAG as well as the NFC reader. The NTAG I2C plus has the unprotected memory starting from page 04h of sector 0, and NDEF messages are stored there. Referring to 8.3.11 of the data sheet, AUTH0 specifies the starting page to be protected, ACCESS[NFC_PROT] enables read&write password protection from NFC interface, PWD and PACK are for password configuration, but before changing any of above , you have to do a password authentication as below: Then you may select sector 0 and read the contents starting from E3h. Here FFh is the default value for AUTH0.  Now you may change the AUTH0,ACCESS[NFC_PROT] , PWD and PACK as you wish, for example, something like below: read the data from E3h to E6h and change the corresponding bytes in one write. The video shows how to read the NDEF message under password protection.  

SPIM module is one of the master interfaces provided by PN7462 , which is a 32-bit ARM Cortex-M0-based NFC microcontroller, and users may use this interface to connect with up to two SPI slave devices. The NFC reader library provides SPIM driver code in phHal/phhalSPIM, and users may directly use the following APIs in their application to implement simple SPI transaction, just like what is done  in the demo of "PN7462AU_ex_phExHif". While this demo has limitation with some SPI nor flash devices, which need a write-read operation in one NSS session, for example, the SPI nor flash device on OM27462 as below: Please note to solder R202 and connect it to 3V3 to make sure nHold pin has pull-up out of POR. The following is one of the command sets this device supports: This command contains 1 write(9F) followed by 3 read operations in one NSS session, but if you implement it with phhalSPIM_Transmit() and phhalSPIM_Receive() as below: status = phhalSPIM_Transmit(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_APPEND_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, 2, cmd_buf, PH_EXHIF_HW_SPIM_CRC_OFFSET);    status = phhalSPIM_Receive(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, data_length, dst, PH_EXHIF_HW_SPIM_CRC_OFFSET);" You will have the following result: expected: NSS   \__________________________/ MOSI     CMD A7-A0 MISO                            DATA       actual:                         NSS   \____________||______________/ MOSI     CMD A7-A0 MISO                           DATA so the pulse between the write and read is the problem, and here we have to handle the NSS line manually, with the help of NSS_VAL and NSS_CONTROL bits in SPIM_CONFIG_REG. so the code should be like this:   Assert NSS   status = phhalSPIM_Transmit(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_APPEND_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, 2, cmd_buf, PH_EXHIF_HW_SPIM_CRC_OFFSET);    status = phhalSPIM_Receive(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, data_length, dst, PH_EXHIF_HW_SPIM_CRC_OFFSET);"   De-assert NSS The NSS line assert and de-assert function can be implemented with register bit level APIs, just like below:             PH_REG_SET_BIT(SPIM_CONFIG_REG, NSS_VAL);//de-assert NSS             PH_REG_SET_BIT(SPIM_CONFIG_REG, NSS_CTRL);             PH_REG_CLEAR_BIT(SPIM_CONFIG_REG, NSS_VAL);//assert NSS Please also include the following header files in your application code. #include "ph_Reg.h" #include "PN7462AU/PN7462AU_spim.h" Please notice that phhalSPIM_Transmit() and phhalSPIM_Receive() are Rom based function, which clear NSS_CTRL bit by default. We can not change ROM API's behave but fortunately we have phhalSPIM_TransmitContinue() and phhalSPIM_ReceiveContinue() instead. so the final solution will be like below: Assert NSS   status = phhalSPIM_TransmitContinue(1, cmd_buf);    status = phhalSPIM_ReceiveContinue(3, dst);   De-assert NSS This doesn't mean phhalSPIM_Transmit() and phhalSPIM_Receive() are useless, because they can also help up to configure the SPI master interface, if you don't want to use register bit level API to initial the SPIM module manually. Please note to use 1 byte for write/read length to make these two functions work properly. so the whole pseudo code is like below: phhalSPIM_Init(PH_HW_SPIM_TIMEOUT) ; phhalSPIM_Configure(PH_HW_SPIM_SLAVE, PH_HW_SPIM_MSB_FIRST,                 \                                     PH_HW_SPIM_MODE, PH_HW_SPIM_BAUDRATE,  \                                     PH_HW_SPIM_NSSPULSE, PH_HW_SPIM_NSSPOL) ; status = phhalSPIM_Transmit(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_APPEND_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, 1, cmd_buf, PH_EXHIF_HW_SPIM_CRC_OFFSET);    status = phhalSPIM_Receive(PH_EXHIF_HW_SPIM_SLAVE, PH_EXHIF_HW_SPIM_INIT_CRC, PH_EXHIF_HW_SPIM_CRC_INIT, 1, dst, PH_EXHIF_HW_SPIM_CRC_OFFSET);" Assert NSS   status = phhalSPIM_TransmitContinue(1, cmd_buf);    status = phhalSPIM_ReceiveContinue(3, dst);   De-assert NSS The following steps show how to create a new project based on NFC reader library, please refer to https://www.nxp.com/docs/en/user-guide/UM10883.pdf  on how to import the NFC reader library. 1. Create a new project after importing the NFC reader library. 2. if you installed PN7462 support package, you will see this: 3. add a link to NFC reader lib: 4. add path and enable NFC reader lib in the project: 5. delete cr_startup.c and create the main code as well as the header file: 6. Build result: 7.Debug result: To fetch the ready demo, please submit a private ticket via the guide of https://community.nxp.com/docs/DOC-329745 . Hope that helps, Best regards, Kan

The NXPNCI-KDS_Example for the PN7120/PN7150 Arduino interface boards available in NXP webpage at the time of publishing this document includes a project compatible with KSDK v2.0 for FRDM-K64F platform. With the latest KSDK v2.1 some changes in the drivers along with the later FreeRTOS v9.0.0 make the build process fail when following the instructions in the application note AN11845 NXP NCI KDS Example due to incompatibilities. Meanwhile until the project in NXP webpage is updated there is a temporary project attached to this document fixed to work with KSDK v2.1. The steps to build this project are the same as explained in the appnote, summarized below: - Download and install KSDK v2.1 for FRDM-K64F using MCUXpresso SDK online builder: Welcome to MCUXpresso | MCUXpresso Config Tools  Create a new workspace in KDS IDE. Import the "NXPNCI-KDS_Example_KSDK2.1" project from the archive file. Update the PROJECT_KSDK_PATH build variable according to the installation path of KSDK v2.1. Build the project. For more details please refer to the application note AN11845. Regards! Jorge Gonzalez

Hello NFC community:   NXP released the new PN7150 NFC Controller chip with enhanced power output, and there is also the new Arduino compatible demokit OM5578/PN7150ARD. See more information in the next pages:   PN7150: High performance full NFC Forum-compliant controlle|NXP OM5578/PN7150ARD: Demoboards for PN7150|NXP   There is also a new PN7120 SBC kit for arduino:   http://cache.nxp.com/documents/user_manual/UM11008.pdf http://cache.nxp.com/documents/user_manual/UM11008.pdf   Due to the Arduino interface pinout, these kits can also be used with Kinetis Freedom Boards. The target of this document is to create projects to use the NFC Controller lîbrary with the PN7120 or PN7150 together with a Kinetis host. Also you will find example projects created for the FRDM-K64F and FRDM-KL43Z.     Requirements:   - Kinetis Software Development Kit v1.3. -> Software Development Kit for Kinetis MCUs|NXP - KDS v3.x with KSDK v1.3 Eclipse Update Installed -> Kinetis Design Studio Integrated Development Enviro|NXP - Kinetis SDK project generator. Available from the "Downloads" tab of KSDK webpage -> Software Development Kit for Kinetis MCUs|NXP     CREATING NEW PROJECT   NOTE: In this step-by-step procedure the FRDM-K64F is used as reference. You can follow the guide according to your own Freedom board.   1) Open the KSDK project generator. 2) Enter the KSDK v1.3 installation path, give a name to the project, select your Freedom board and click on "Advanced":     3) In the advanced settings window enable the checkboxes for:   - Include BSP files - Generate standalone project - Kinetis Design Studio toolchain - Board (confirm that your board is shown in the drop-down menu)   NOTE: The path for the newly created project is set by default inside of the KSDK v1.3 installation. For a standalone project you can change the location, just remember such path to import the project to KDS workspace in a later step.   Leave the rest of configurations as default (New project, Platform library, no RTOS) and finally click on "Advanced Generate!".     4) From Kinetis Design Studio go to File -> Import.     5) Go to General -> Existing Projects into workspace and click "Next".     6) In "select root directory" browse to the location of the platform lib for the created project. By default this path would be:   C:\nxp\KSDK_1.3.0\examples\frdmk64f\user_apps\<project_name>\lib\ksdk_platform_lib\kds\<MCU>   <project_name>: The name given initially to the project. <MCU>: The corresponding device number (K64F12 in this case).   Make sure that the project check box is enabled and click on "Finish".     7) Select the KSDK platform library project and click on the "Hammer icon" to build it.     😎 Repeat steps 4 through 6, but this time browse to the location of the application project. In this example the path is:   C:\nxp\KSDK_1.3.0\examples\frdmk64f\user_apps\< project_name >\kds     INTEGRATING NFC CONTROLLER LIBRARY   The next steps describe how to integrate the NFC NCI library to your newly created project.   - The Arduino Interface Boards use the next pinout for communication between the OM5578/PN7150 or OM5577/PN7120 kits with the Freedom or Arduino boards:     As shown in the picture, the pinouts are similar except for the 5V connection. This leverages the enhanced output power feature of the PN7150 NFC Controller.   - We need to check the corresponding pins that will be used from the Freedom board. In this case, the connections to the FRDM-K64F board would be as next:   IMPORTANT: The pinout shown below corresponds to Rev E3 schematics of FRDM-K64F. For Rev D1 the pin used for IRQ (header location J2[2]) must be PTA0 instead of PTC12.     1) Open the file gpio_pins.c and add 2 pin configurations: 1 input pin called NFCCirqPin and 1 output pin called NFCCvenPin.   gpio_input_pin_user_config_t NFCCirqPin = {   .pinName = kGpioNFCCirq,   .config.isPullEnable = false,   .config.pullSelect = kPortPullUp,   .config.isPassiveFilterEnabled = false,   .config.interrupt = kPortIntDisabled, }; gpio_output_pin_user_config_t NFCCvenPin = {   .pinName = kGpioNFCCven,   .config.outputLogic = 1,   .config.slewRate = kPortSlowSlewRate,   .config.driveStrength = kPortLowDriveStrength, };   2) In the file gpio_pins.h add 2 extra elements to the gpio enumeration. Also add extern declarations for the 2 pins defined in the previous step.   NOTE: For FRDM-K64F the pins are PTC12 and PTC3. Select corresponding pins for your Freedom board.   extern gpio_input_pin_user_config_t NFCCirqPin; extern gpio_output_pin_user_config_t NFCCvenPin; /*! @brief Pin names */ enum _gpio_pins_pinNames {   kGpioSW2  = GPIO_MAKE_PIN(GPIOC_IDX, 6U),   kGpioSW3  = GPIO_MAKE_PIN(GPIOA_IDX, 4U),   kGpioSdhc0Cd  = GPIO_MAKE_PIN(GPIOE_IDX, 6U),   kGpioLED1     = GPIO_MAKE_PIN(GPIOE_IDX, 26U),   kGpioLED2     = GPIO_MAKE_PIN(GPIOB_IDX, 22U),   kGpioLED3     = GPIO_MAKE_PIN(GPIOB_IDX, 21U),   kGpioNFCCirq  = GPIO_MAKE_PIN(GPIOC_IDX,  12), /* GPIO for NFCC IRQ pin */   kGpioNFCCven  = GPIO_MAKE_PIN(GPIOC_IDX,  3),  /* GPIO for NFCC VEN pin */ }   3) In the file pin_mux.c define a function to configure the MUX setting of the required GPIO and I2C pins to interface with the NFC Controller.   void configure_nfcc_pins(void) {   /** I2C_SDA **/   PORT_HAL_SetMuxMode(PORTE,25u,kPortMuxAlt5);   PORT_HAL_SetOpenDrainCmd(PORTE,25u,true);   /** I2C_SCL **/   PORT_HAL_SetMuxMode(PORTE,24u,kPortMuxAlt5);   PORT_HAL_SetOpenDrainCmd(PORTE,24u,true);   /* NFCC IRQ */   PORT_HAL_SetMuxMode(PORTC,12u,kPortMuxAsGpio);   /* NFCC VEN */   PORT_HAL_SetMuxMode(PORTC,3u,kPortMuxAsGpio); }   NOTES: - Check the corresponding pins on your Freedom board. FRDM-K64F uses PTC12/PTC3 as GPIOs while PTE24/PTE25 are configured as I2C pins. For I2C pins also check the MUX number in the device's Reference Manual (e.g. PTE24/PTE25 in K64F have the I2C function in ALT5). - This function needs to be called from your project to configure the required pins. e.g. from hardware_init(). - Some Freedom boards share the I2C pins of the Arduino compatible header with an on-board I2C device (e.g. accelerometer), with SDA/SCL pull-up resistors populated already. If this is not the case for your board, make sure to place external pull-ups to  MCU VDD or enable the internal pull-ups as temporary workaround.   4) Add the prototype of the function to the header file pin_mux.h.   /* ** =================================================== **     Method :  configure_nfcc_pins */ /*! **     @brief **         Set mux configuration for I2C and GPIO pins **         to interface with the NFC Controller. */ /* ==================================================*/ void configure_nfcc_pins(void);   5) Copy the folders NfcLibrary and TML to the project folder. The file fsl_i2c_irq.c is also required. In this case the file is found in the next path:   C:\nxp\KSDK_1.3.0\examples\frdmk64f\user_apps\<project_name>\platform\drivers\src\i2c   NOTE: If the project was not created in standalone mode, just search the fsl_i2c_irq.c file from your KSDK installation.       6) Add the NfcLibrary and TML folders with all its subfolders and files to the project's tree, so the lilbrary is part of the build. Also add the file fsl_i2c_irq.c to the project. In KDS you can drag and drop folders and files to the project explorer view.       7) Add the compiler include paths for the inc folders.     😎 From the KDS preprocessor settings add or remove the next conditional compilation macros according to your functional requirements:   CARDEMU_SUPPORT: The NFC Controler host (MCU) can emulate a contactless card which can be accessed by an external Reader/Writer. P2P_SUPPORT: The host MCU can establish a 2-way communication accesing to or sending data to an external Reader/Writer. RW_SUPPORT: With this mode the host can access a remote contactless tag/card via the NFC Controller. NCI-DEBUG: If defined, all information transferred between the host MCU and the NFC Controller Interface (commands, responses, notifications, data) is echoed to console for debug purposes.     9) The file tml.h includes the macro NFCC_I2C_INSTANCE which defines the I2C module to use. For FRDM-K64F the module is I2C0. Set this macro according to your Freedom board.   /* NFC Controller I2C interface configuration */ #define NFCC_I2C_INSTANCE  0   At this point the project is ready to use the NFC Controller library and interface the Kinetis Freedom board with PN7120 or PN7150 NFC Controllers.     DEMO PROJECTS   At the end of this document you will find 2 example project packages for the FRDM-K64F and FRDM-KL43Z. Both of the projects can be used with either the OM5578/PN7150 or OM5577/PN7120 kits using the Arduino interface boards.   Each ZIP package includes 2 projects (example application and KSDK library). Unzip the package and import the projects from the resulting location.   Do not select "Copy projects into workspace" in KDS. If you do so the build will fail due to the linked source files not copied over.   The projects must be built in the next order:   1- Platform library project (FRDM-xxx_NFCNCI_Example\lib\ksdk_platform_lib\kds\<MCU>) 2- Demo project (FRDM-xxx_NFCNCI_Example\kds)   The OpenSDA virtual COM port is used to send data to a terminal at 115200 baud. Below an explanation on how to test the different project example features.   RW mode:   - Placing a tag with a single text, URI or vCard NDEF record next to the NFC reader antenna. Examples:         P2P mode:   - Bring an android phone with NFC enabled close to the NFC controller antenna and use the "beaming" feature. In the case below the NXP home page is "beamed" from the adroid phone's explorer. After this, the NFC enabled phone will receive the "Test" NDEF record.                     CARD EMULATION mode     For this mode it is required to remove the P2P_SUPPORT macro and rebuild/reprogram the project.   - Bringing an android phone set to read a NFC tag close to the NFC controller board. The NFC enabled phone will detecta T4T tag type with the "Test" NDEF record.     I hope you can find this document useful. Any questions or doubts please let me know in the comments.   Jorge Gonzalez NXP Technical Support

This is a step by step guide on setting up and running a simple NFC Demo App using the PN7150 NFC Controller SBC Kit for Arduino (OM5578/PN7150ARD) with a UDOO NEO board which uses an i.MX6SX and it's Arduino pin compatible. 1. Requirements - UDOO NEO board. This document refers to the UDOO NEO Full board, but the steps remain the same for all UDOO Neo boards as long as the appropriate Device Tree is used for each. For more information on this board please go to the official site (http://www.udoo.org/) UDOO Neo Full Board - PN7150 NFC Controller SBC Kit for Arduino (OM5578/PN7150ARD) which is shown on the image below. Alternatively you may use the PN7120 NFC Controller SBC Kit for Arduino (OM5577/PN7120ARD). PN7150 NFC Controller SBC Kit for Arduino mounted over the UDOO Neo You may find more details about the OM5578 board on the user manual (Doc ID UM10935) which is available on the following link. http://www.nxp.com/documents/user_manual/UM10935.pdf You may also find additional documentation and information of this and other PN7150 demoboards on the link below: Demoboards for PN7150|NXP​ You may find more details about the OM5577 board on the user manual (Doc ID UM10878) which is available on the following link. http://www.nxp.com/documents/user_manual/UM10878.pdf For additional resources for the OM5577 board please refer to the link below. PN7120 NFC Controller SBC Kit|NXP - Host computer with Ubuntu 12.04 or later (14.04 is preferred). - L3.14.28 BSP Release for the i.MX6SX installed on the host. You may find the documentation on how to download and setup this BSP on the following link. http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/i.mx-applications-processors/embedded-linux-for-i.mx-applications-processors:IMXLINUX?code=IMXLINUX 2. Setting up NXP BSP Release and Toolchain Follow the instructions on the Yocto User’s Guide included on the L3.14.28 BSP Release to setup and build an image to for the i.MX6SX (MACHINE= imx6sxsabresd). We’ll be using the fsl-image-gui image with frame buffer (fb) backend. Other images may be used but please keep in mind that the core-image-minimal image does not include the libstdc++.so.6 library required by the NFC Demo App. It is also necessary to build and install the toolchain for cross compiling the kernel and bootloader. This can be done with the following command: $ bitbake meta-toolchain Once created you may install it by running the following script: <BSP_DIR>/<BUILD_DIR>/tmp/deploy/sdk/poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.7.sh For more details on how to extract the toolchain please refer to the following Yocto Training Task: Task #7 - Create the toolchain 3. Editing the Device Tree In previous versions (3.0.35 backward) the Linux Kernel used to contain the entire description of the hardware so the bootloader just had to load the kernel image and execute it. In current Kernel versions the hardware description is located in the device tree blob (DTB), which allows for the same Kernel to be used in different Hardware by changing only the Device Tree. In this scenario the bootloader loads the Kernel image and also the Device Tree (DTB) binary. For more details on how to add a new Device Tree please look at the following Community Document that covers adding a new device tree: https://community.nxp.com/docs/DOC-329664 For this document we will change the current UDOO NEO Device Tree as we will only be adding support for the PN7150 NFC Controller Board. 3.1 Copying the original UDOO Neo Device Tree files Create a development folder in your home directory. mkdir udooneo-dev Download the kernel source into this folder. This also includes the device tree files. cd udooneo-dev git clone https://github.com/UDOOboard/linux_kernel The Device Tree files will be available at  udooneo-dev/linux_kernel/arch/arm/boot/dts 3.2. Editing the UDOO Neo Device Tree Files We will be using the UDOO Neo Full board, so we will be using the imx6sx-udoo-neo-full-hdmi-m4.dts. If we look into this file using a text editor we will see that it includes several include definition files which are also located in the same directory. #include "imx6sx-udoo-neo.dtsi" #include "imx6sx-udoo-neo-full.dtsi" #include "imx6sx-udoo-neo-m4.dtsi" #include "imx6sx-udoo-neo-hdmi.dtsi" #include "imx6sx-udoo-neo-externalpins.dtsi" We will need to copy these to the BSP Release dts directory (you may alternatively build the device tree from this directory, but we will cover how to add device trees to the BSP Release in this document): /<BSP_DIR>/<BUILD_DIR>/tmp/work/imx6sxsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git/arch/arm/boot/dts/ We will need to add the new dtb file to be compiled on the Makefile from the BSP Release.  This needs to be placed inside the precompiler directive $(CONFIG_ARCH_MXC) There are some additions that must be made to device tree in order to configure the pins used by the NFC controller Board which uses the Arduino Pinout. These can be done to the imx6sx-udoo-neo.dtsi so they are taken by any UDOO Neo Device Tree we compile. The I2C pins used are those of the I2C2 bus. The configuration for these pins should be already implemented on the imx6sx-udoo-neo.dtsi file. If not please add these lines inside the &iomuxc section. &iomuxc {                         pinctrl_i2c2_1: i2c2grp-1 {                                         fsl,pins = <                                                         MX6SX_PAD_GPIO1_IO03__I2C2_SDA          0x4001b8b1                                                         MX6SX_PAD_GPIO1_IO02__I2C2_SCL           0x4001b8b1                                         >;                       }; }; Then we need to add the pn547 entry into the &i2c2 section for the enable pin, interrupt pin, I2C address and buss speed for the PN7150. Put what is in bold below at the end of the “&i2c2” section as shown. &i2c2 { pn547: pn547@28 { compatible = "nxp,pn547";                 reg = <0x28>; clock-frequency = <400000>; interrupt-gpios = <&gpio4 9 0>; enable-gpios = <&gpio5 21 0>;         }; }; Important Note: Prior to adding either of these configurations it is critical that you ensure these pins and I2C addresses are not used anywhere else in this and other *udo*.dtsi files You may find the UDOO Neo Schematics on the UDDO website (link to the schematics below) to see the reason behind these settings. http://www.udoo.org/download/files/schematics/UDOO_NEO_schematics.pdf IR Signal – J4 Connector – Arduino 7 pin – i.MX6SX B13 pin VEN Signal - J6 Connector – Arduino 8 pin - i.MX6SX W5 pin SDA Signal – J6 Connector – Arduino SDA pin - i.MX6SX D20 pin SCL Signal – J6 Connector – Arduino SCL pin - i.MX6SX C20 pin If you want to review in more detail how to create a simple Device Tree from scratch please check the following very complete and easy to follow Community Document. Basic Device Tree for the Udoo Board To compile the device tree run the following command source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi cd /<BSP_DIR>/<BUILD_DIR>/tmp/work/imx6sxsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git make ARCH=arm dtbs This will produce the Imx6sx-udoo-neo-full-hdmi-m4.dtb that will be used. 4. Compiling U-Boot We will be using the UDOO U-boot for the UDOO Neo Full board. The following steps describe how to download the source code and compiling it using our toolchain. Downloading the source code mkdir UDOOneo-dev cd UDOOneo-dev git clone -b 2015.04.imx-neo https://github.com/UDOOboard/uboot-imx cd uboot-imx Compiling u-boot source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- make udoo_neo_config ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- make This will generate a SLP file with the DCD (Device Configuration Data) table and the u-boot.img file. Note: By default this U-Boot configuration detects the UDOO Neo board and in our case it would look for the imx6sx-udoo-neo-full-hdmi-m4.dtb. You may need to use a different device tree depending on your board. 5. Flashing SD Card 5.1. Using the .sdcard file to load the BSP Release Image The easiest way to load the Root File System from our image is using the .sdcard file that is created after running bitbake. This image will be located on the following path: /<BSP_DIR>/<BUILD_DIR>/tmp/deploy/images/imx6sxsabresd This will also load the BSP Release U-boot and device tree files but we will then exchange for our own. To do this use the following command where sdx is your SD Card. $ sudo dd if=<image name>.sdcard of=/dev/sdx bs=1M && sync Alternatively we can manually create the two partitions needed. For more information on this please refer to the Yocto User’s Guide. 5.2. Writing U-boot To flash U-boot you need to flash both the SPL file and the u-boot.img file using the following commands assuming that your SD card is in /dev/sdx dd if=SPL of=/dev/sdx bs=1K seek=1 dd if=u-boot.img of=/dev/sdx bs=1K seek=69 5.3. Copying the Device Tree Blob Copy the imx6sx-udoo-neo-full-hdmi-m4.dtb device tree to a folder called dts on the FAT partition. 6. Adding Kernel Driver Download the driver source from the git repository from the Linux source directory cd /<BSP_DIR>/<BUILD_DIR>/tmp/work/imx6sxsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git/drivers/misc $ git clone https://github.com/NXPNFCLinux/nxp-pn5xx.git Add the line below to the Makefile of the current directory     obj-y += nxp-pn5xx/ Include the driver config by adding below line to the heading configuration file (drivers/misc/Kconfig). source "drivers/misc/nxp-pn5xx/Kconfig" Export the environment variables cd /<BSP_DIR>/<BUILD_DIR>/tmp/work/imx6sxsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git/     $ source /opt/poky/1.7/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi     $ export ARCH=arm     $ export CROSS_COMPILE=$TARGET_PREFIX     $ make imx_v7_defconfig make menuconfig Inside menu config include the driver as a module (<M>), which is on the path: Device Drivers --->       Misc devices --->     < M> NXP PN5XX based driver Save the changes and exit, and then compile the modules. $ make modules We will then install the modules to our image. Insert the SD card with the loaded image and mount it to access it from the command promt. sudo mount /dev/sdx ~/mountpoint/ Where sdx is your SD card. Then use the following command to install the modules. sudo ARCH=arm INSTALL_MOD_PATH=/home/user/mountpoint modules_install firmware_install Before unmounting our SD card we will install the NFC library. 7.Installing the NFC library. Install the necessary libraries on the host by running the following commands: sudo apt-get update sudo apt-get install automake sudo apt-get install autoconf sudo apt-get install libtool Note: In case you are using Ubuntu 12.04 the following commands will allow for autoconf 2.69 to be installed, which is the minimum version required by the NFC library. sudo add-apt-repository ppa:dns/gnu -y sudo apt-get update -q sudo apt-get install --only-upgrade autoconf Enter our directory and install the Linux libnfc-nci stack cd ~/UDOOneo-dev git clone https://github.com/NXPNFCLinux/linux_libnfc-nci.git Generate the configuration script by executing the bootstrap bash script cd ~/UDOOneo-dev/linux_libnfc-nci ./bootstrap Configure Make file. We are using the default toolchain sysroots path. To configure for the PN7150 please use the following settings: ./configure --enable-pn7150 --host=arm-none-linux --prefix=/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr --sysconfdir=/home/user/mountpoint/etc To configure for the PN7120 please use the following settings: ./configure --enable-pn7120 --host=arm-none-linux --prefix=/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr --sysconfdir=/home/user/mountpoint/etc We are ready to execute the make and install the stack. make sudo make install After a successful build the libraries and a application demo are built in .libs directory. Copy the libraries to “/usr/lib” directory of the target and nfcDemoApp to the targets “/usr/sbin” cd .libs sudo cp * /home/user/mountpoint/usr/lib sudo cp nfcDemoApp /home/user/mountpoint/usr/sbin cd ~/UDOOneo-dev/linux_libnfc-nci/conf/PN7150 sudo cp * /home/user/mountpoint/etc Now we can unmount our SD card. sudo umount /home/user/mountpoint 8. Testing the NFC Reader Insert the micro SD card into the slot of the UDOO Neo board and install the PN1750 NFC Controller board on top of the UDOO Neo board. We will be using the terminal console in order to access the board. You may use the official USB/Serial debug module for NEO or a similar adapter. For more information on setting up the Serial Debug Console on the UDOO Neo board please refer to the link below. http://www.udoo.org/docs-neo/Basic_Setup/Serial_Debug_Console.html Once it has booted, install the .ko file. insmod /lib/modules/3.14.28+g91cf351/kernel/drivers/misc/nxp-pn5xx/pn5xx_i2c.ko Then run the nfcDemoApp. We’ll test it in poll mode, where it looks for available tags and reads them. nfcDemoApp poll You should get a console output as shown below when placing a NFC tag next to the NFC reader.

The latest NFC reader library supports lpc1769 which is a cortex M3 controller with LPCopen lib supports, so in theory , it should supports other controllers supported by LPCopen, but we have to test this, so we choose , for example, lpc11u37, a cortex M0 based controller for this porting. Platform for this porting: LPC11u37h-Xpresso Rev A: CLRC663 plus based CLEV663B Blueboard 3.0. Please refer to Prepare CLEV663B board for NFC reader library porting  for details. They are connected via LPCXpresso ports. Now we may start the porting, the IDE we use in this porting is MCUXpresso 10.1.1 1. Download and import the latest NFC reader library for CLEV6630B, as it supports CLRC663 plus. For how to import the project, please refer to https://www.nxp.com/docs/en/application-note/AN11211.pdf . 2. Download LPCopen for LPC11u37h and import it as well. 3. Now we may choose some demo in the NFC reader library, for example, the NfcrdlibEx1_BasicDiscoveryLoop, and create new build configuration for lpc11u37h. 4.Select the correct MCU 5.Modify build settings Here we find LPC1769RC663 is defined, so we have to find what is related with this definition in the code and change it/them. Fortunately they are not too many. you may find they are just related with board header file including or something like that, so it is not difficult to modify them. 6. Add new header file for the new board definition 7. add the new board definition 8. As we now use LPCopen lib for LPC11u37h instead, so we have to change the including path. As LPC11u37h is cortex M3 based, so we have to setup FreeRTOS for M0 support: and add the source code for building: 9.Change the link libraries and including path 10.Set the correct ref projects to use LPCopen for LPC11u37h. 11. Some changes in LPCopen library: 1)enable semihosting debug 2) add startup source code for the demo, this C file can be reused/imported from the some lpcopen project. 12. After the above steps, we still have to change the source code in DAL: You know , due to different version of LPCopen library,  some function definition might be changed, and different LPCXpresso boards has different pin connection to the LPCXpresso ports, so it is recommended checking the board schematics and the examples in lpcopen project , find the proper function calls to implement the source codes in the DAL folder. When you finished , the porting is done. 13. As the final image size is greater than 128K, we have enable optimization for size. 14.Demo test ok. Now , we know lpc11u37 can be supported by the latest NFC reader library, so the porting should also be applied for other Cortex M0 controllers, and it is recommended the controller with large internal flash size, better greater than 128K, but anyway, in this porting, I didn't enable the size optimization for LPCopen library, so there might be possibility to have a smaller size image at last...

Hello NFC Community, This document describes how to write multiple NDEF Text Record by making use of NFC TagWriter app by NXP. First of all, download the TagWriter app from the Play Store: NFC TagWriter by NXP - Apps on Google Play  1) Once downloaded, go to the Write tags section. 2) In this case, a NDEF text record will be written. 3) Write a text message in the TextBox and press the Save & Write Button. 4) Now, press the ADD MORE RECORD Button so that another record can be added to the content to be written in the tag. 5) Select Plain Text again.   6) Same, procedure as in 3. 7) Finally, Tap the card and press the DONE Button.
