Introduction I am trying to make one page that contain all the useful information about NFC Antenna Design. I will keep update and add the information to this page when I found something useful.   Training First of all, there are 6 webinars about NFC Antenna Design. It is a good training before to start your antenna design for NFC. Training & Events | NXP  (Search "Antenna design")   Application Notes AN11740 : PN5180 Antenna design guide AN11706 : PN7462AU Antenna design guide AN11019 : CLRC663, MFRC630, MFRC631, SLRC610 Antenna Design Guide AN11755 : PN7150 Antenna Design and Matching Guide AN11564 : PN7120 Antenna Design and Matching Guide AN11741 : How to design an antenna with DPC AN11535 : Measurement and tuning of a NFC and Reader IC antenna with a MiniVNA Tools NFC Antenna Design Hub

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:

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.

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.

The latest NXP-NCI example is rev 1.6, and when you run this demo with the lpc11xx board, for example, lpc1115 rev A, and the OM5577, you may meet the following issue: The problem is due to two aspects: one is hardware and the other is software. For hardware solution, besides following what is described in AN11658 section 2.4 LPC11xx, you have to do one more thing: a) The I2C lines are not pulled-up: LPC11xx doesn't offer internal pull-up setting of the I2C lines so external pull-up resistors must be added. For software solution, the function of Sleep()( in tool.c) was optimized too much, and it didn't meet the timing requirement of OM5577, so we should let the IDE ignore it. The solution I use is as below: __attribute__((optimize("O0"))) void my_func() { blah } You may check the attachment for details. The result is shown as below: Original Attachment has been moved to: tool.c.zip

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 and Kinetis enthusiasts, NTAG I2C plus tag ICs offer both, a contact (I2C) and a contactless interface (NFC) to ease the development of IoT, home-automation and consumer applications. The target of this document and the example projects is to show how NTAG I2C plus can act as the bridge from a host NFC device, like a smartphone or PC, to an embedded board such as a Kinetis Freedom board. 2 main functionalities are demonstrated: embedded board control via NFC and firmware upgrades over NFC. Board control with NFC enabled device NTAG I2C plus provides an easy way of sending/receiving any kind of data between a product embedding an MCU to a host NFC device (e.g. smartphone). Some use cases include product configuration, control or data sensing. A major advantage is that we can have a customized application or graphic interface in the smartphone instead of expense of an LCD screen for the embedded board. Bootloader over NFC Firmware updates in the field are a very common practice for products based in an embedded system. The main advantages of a bootloader over NFC are the simplicity and the non intrusive nature, as it communicates using NFC antennas, i.e. without any wires or physical connections. DEMO PROJECT The next picture shows the setup and connections from the NTAG I2C Plus antenna board to the FRDM-K64F. Hardware - Kinetis Freedom board FRDM-K64F - NTAG I2C Plus Antenna board or flex antenna with the NTAG I2C plus IC. Software - Kinetis Software Development Kit (KSDK) v2.0 - Kinetis Design Studio (KDS) v3.2 - NTAG I2C Demo Android application. Available from Google Play. :smileyalert: Note: Please verify that your smartphone supports NFC. Otherwise the Android app can be installed but it cannot be used for interfacing with the NTAG I2C Plus IC. TESTING THE DEMO PROJECTS There are two KDS projects attached to this document: - NTAG_I2C_Plus_FRDMK64_Demo: Demonstrates the transfer of data between the phone and the MCU. - NTAG_I2C_Plus_FRDMK64_Bootloader: Provides a mean to update the firmware in the Kinetis MCU. The application must be prepared to be placed at an offset of 0x4000 in the MCU internal flash. To load any of these demos please open the corresponding project in KDS IDE, build the project and start a debugger session to program the K64. NTAG_I2C_Plus_FRDMK64_Bootloader 1- In FRDM-K64F, SW2 must be pressed during reset to enter bootloader mode. Hence the 2 usual ways are:+    A) If the board is powered, press and hold SW2 and then press Reset button.    B) When the board is not powered, press and hold SW2 and then plug the USB cable. 2- From the Android demo app go to the "Flash" option. Then click on "Select from Storage" to browse for the application binary file. :smileyinfo: Note: For this bootloader example, the application including the vector table must be relocated to an offset of 0x4000 in Flash. 3- Finally tap the phone to the NTAG I2C Plus antenna and hold it steady during the flashing progress. When the app shows "Flash Completed" the new application starts executing. NTAG_I2C_Plus_FRDMK64_Demo :smileyalert: NOTE: By default the demo project has the 0x4000 offset, so please build the project and then load the generated binary using the bootloader as described above. - Bring the NFC enabled phone near the NTAG I2C Antenna. - Verify transfer is already in progress, by checking the "Board Status". - Press the Orange/Blue/Green buttons in the Android app to change the color of the RGB LED. - Enable the checkbox for "Enable Temperature Sensor" to see the reading of the K64 internal temperature. I hope these demo projects are useful. Please feel free to share your comments or ask any questions. Regards! Jorge Gonzalez

The NFC reader library is supporting multiple frontends. For a customer this might become a more difficult to use, if only the part for one of the frontend chips is needed. To enhance the readability and usability, you can remove the support for not used reader ICs by simply removing the folders below NxpRdLib/comps/phhalHw/src. For instance: if you only want to use the RC663, you could simply delete the folders Pn5180, Rc523. The result would be a library that only supports RC663. This short screen recording shows the steps to reduce the number of supported Frontends.

AN13189 provides guidelines for the integration of PN7160 NXP NCI-based NFC controller to an Android platform from software perspective. But some developers found some compile issues when integrating PN7160 NFC package into Android 11.   This article describes how to fix the build error when you integrating PN7160 NXP NCI-based NFC controller to Android 11 system.  You need to follow the AN13189 (PN7160 Android porting guide ) first.  After you run the installation script install_NFC.sh, the following modification should be added to the source code. 1) Open package/apps/Nfc/nci/jni/Android.bp Add  "-DNXP_EXTNS=TRUE",   2 )  open system/nfc/src/Android.bp Add   "-DNXP_EXTNS=TRUE",     3 )   open packages/apps/Nfc/src/com/android/nfc/NfcService.java And add this: between isNfcSecureEnabled and setNfcSecure methods:             @Override         public IBinder getNfcAdapterVendorInterface(String vendor) {             if(vendor.equalsIgnoreCase("nxp")){                     return (IBinder) mNfcAdapter;             } else {                    return null;             }         }     Next, follow AN13189, complete the following steps in section 4.2. Then you can build the package successfully.  Thanks  @andraz_skupek .
