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 .

This post contains a step by step guide of how to use PN7150 with i.MX RT1060. This document is structured as follows: Overview of PN7150 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 Hardware Requirements      1. OM5578/PN7150ARD      2. i.MX RT1060 EVK Evaluation Board + usb micro cable        Using PN7150 with i.MX RT1060 Hardware Connections The hardware connections are simple. Both the EVKB-IMXRT1060 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 EVKB-IMXRT1060 board.  Running the Demo If this is the first time you’re using EVK-MIMXRT1060 board, follow the getting started guide first:  i.MX RT1060 Evaluation Kit | NXP . Make sure to install the SDK package for EVK-MIMXRT1060 board which is required for the project to run.   Download the ‘evkbimxrt1060_PN7150’ 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 from here: https://www.nxp.com/support/developer-resources/software-development-tools/mcuxpresso-software-and-tools/mcuxpresso-integrated-development-environment-ide:MCUXpresso-IDE 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: After step 3, 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.

     This document mainly describes how to use NanoNVA tool to do antenna tuning on OM29263ADK with CLEV663B/PN5180B board. Please refer to the application note AN12810(https://www.nxp.com/docs/en/application-note/AN12810.pdf) about the NanoVNA tool. And please refer the user manual UM11098 (https://www.nxp.com/docs/en/user-guide/UM11098.pdf) about OM29263ADK. After setting NanoVNA tool with reference to the above documents. Firstly, take the small antenna of OM29263ADK with CLEV663B as an example. The small antenna can be directly connected and used on the CLEV6630B。 the antenna board can be directly connected to the CLEV6630B without any additional modification, after the original antenna had been removed (cut off).   The result of the antenna tuning with NanoVNA tool as the below:   Second, take the small antenna of OM29263ADK with PN5180B board as an example. Follow the UM11098 steps as the below: (a) the EMC filter cut off frequency must be adjusted, and (b) the DPC and related features should be disabled, since the antenna is asymmetrically tuned and the DPC is not used. (a) The original antenna uses a symmetrical tuning, which uses an EMC filter with L0 = 470nH and C0 = 253pF (220pF + 33pF). The inductor as well as the first part of the capacitance (220pF) are assembled on the main board. To operate the OM29263ADK antenna, the C0 (220pF) on the PNEV5180B must be replaced by a 68pF.   (b) The DPC and its related features should be disabled to operate an asymmetrical antenna.   If can’t get the card information please refer to the AN11740’s related steps to achieve a good sensitivity of RxP/RxN path. The result of the antenna tuning with NanoVNA tool as the below:   The whole process of the small antennas tuning of OM29263ADK with CLEV66B/PN5180 with NanoVNA is completed. PS: It is the similar with the steps for the large antennas tuning of OM29263ADK with CLEV66B/PN5180 with NanoVNA.

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.

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

Hello NFC enthusiasts, The following topics will be covered in this document: Activation of multiple Tags. For more information, please refer to Activating multiple Tags using NFC Reader Library  Read and Write NDEF messages. Reading values from GPIOs. This document will be segmented into three parts: Description. Software configuration section. Hardware configuration section. Demonstration. Description. The purpose of this project is to copy the information stored from one tag to another by making use of GPIOs to decide which tag to copy from. This way, topics such as read and write NDEF, card activation and GPIOs will be implemented.   Software configuration section: This demonstration is based on NXP NFC Reader Library v05.02.00, NfcrdlibEx3_NFCForum project for PNEV7462B, in which some modifications are going to be made in order to carry this out. These tags are compliant with NFC Forum Type 2 Tag and ISO/IEC14443 Type A specifications.    In phacDiscLoop.h modify the max number of cards supported (two cards for this demonstration):   #define PHAC_DISCLOOP_CFG_MAX_CARDS_SUPPORTED 0x02U      In NfcrdlibEx3_NFCForum.c add the following code in  LoadDiscoveryConfiguration():   static phStatus_t LoadDiscoveryConfiguration ( ) { . . . /*Passive max typea devices*/ status = phacDiscLoop_SetConfig ( pDiscLoop , PHAC_DISCLOOP_CONFIG_TYPEA_DEVICE_LIMIT , 2 ) ; CHECK_STATUS ( status ) ; }   A fix to the SW stack has to be made (Fix will be implemented in the next release): open "phacDiscLoop_Sw_Int_A.c", line 511, change if statement as below.     if ( ( pDataParams -> sTypeATargetInfo . bTotalTagsFound > 1 ) && ( ( bTypeATagIdx ) < pDataParams -> sTypeATargetInfo . bTotalTagsFound ) )   In NfcrdlibEx3_NFCForum.c add #include "phhalGpio.h" to local headers section. /* Local headers */ #include <cards.h> #include "phhalGpio.h" #include "NfcrdlibEx3_NFCForum.h" ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ In  NfcrdlibEx3_NFCForum.c define uint16_t NDEFlength = 0 and declare void InitGPIOs(void) in Global Defines section. /******************************************************************************* **   Global Defines *******************************************************************************/ phacDiscLoop_Sw_DataParams_t       * pDiscLoop ;        /* Discovery loop component */ void * ppalI18092mPI ; void * ppalI18092mT ; void * palTop ; /* Variables and InitGPIOs() needed for this application */ uint8_t bTagState1 ; uint8_t * value ; uint8_t * value1 ; uint8_t val , val1 ; uint16_t NDEFlength = 0 ; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍ void InitGPIOs ( void ) ; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ in Main Function, initialize the following: /******************************************************************************* **   Main Function *******************************************************************************/ int main ( void ) {      /* Initialize section */      value = & val ;      value1 = & val1 ;      InitGPIOs ( ) ; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ In case of multiple devices (which is of our interest) add the following code and comment the if(wNumberOfTags > 1){...} section as follows: else if ( ( status & PH_ERR_MASK ) == PHAC_DISCLOOP_MULTI_DEVICES_RESOLVED )             {                 /*                  * Multiple cards resolved.

Based on NFC reader library porting guide for LPC11u37h(Ver 5.12) ,We have a partial ported NFC reader library like below: Now, it is time to port other demos in this project. You may choose any demo, but here NfcrdlibEx2_AdvancedDiscoveryLoop is selected. and similar with before, the first step is creating a new build configuration: then in the project references, choose the LPCopen library for LPC11u37 instead. Change the MCU settings: Change the build settings: Change FreeRTOS portable to cortex M0: Search "PHDRIVER_LPC1769RC663_BOARD" in the source code of "NfcrdlibEx2_AdvancedDiscoveryLoop" project, and you may simply replace it with "PHDRIVER_LPC11U37RC663_BOARD", and there are only two places needs to be fixed. Search "PHDRIVER_LPC1769" in the source code of "NfcrdlibEx2_AdvancedDiscoveryLoop" project, and you may simply replace it with "PHDRIVER_LPC11U37". Most changes are in phApp_Init.c. Also please don't forget to enable optimization for size. Building result: Demo testing result:

This post contains a guide of how to use the NFC Reader Library with LPC845 using the Basic Discovery Loop example. The vanilla Basic Discovery Loop example is larger than the flash size of LPC845 (64KB), so the project needs to be reduced in size as well. How to reduce the size is explained in section “Porting the NFC Reader Library and reducing the size of project” A ready to use package “lpcxpresso845max_Basic_Discovery_Loop” example from the NFC Reader Library to be run on LPC845 and CLRC663 plus frontend is attached with this document. This document is structured as follows:   Overview of LPC845 The LPCXpresso-MAX family of boards provides a powerful and flexible development system for NXP's low-end Arm® Cortex®-M0+ based MCUs. They can be used with a range of development tools, including the MCUXpresso IDE toolchain. The LPCXpresso845-MAX board was created to enable evaluation of and prototyping with the LPC84x family of MCUs. Based on the Arm® Cortex®-M0+ core, LPC845 is a low-cost, 32-bit MCU family operating at frequencies of up to 30 MHz. The LPC845 MCU contains 64 KB of flash memory and 16 KB of SRAM.  Hardware Requirements Following hardware is required to run the project: LPCXpresso845-MAX development board. CLEV6630B board or BLE-NFC-V2 board. Both boards contain CLRC663 plus frontend. Here we use BLE-NFC-V2.   Connections Connect the two boards as follows: Porting the NFC Reader Library and reducing the size of Project: The porting of Basic Discovery Loop Example (NFC Reader Library) to LPC845 Max was done following the procedure mentioned in “NFC Reader Library Porting to i.MX RT1050” document. However, after completing the porting and building the project, the size of the binary, which is 134.264 KB, is greater than the size of Flash of LPC845 which is 64KB of flash. To reduce the size of the project, the following two steps were taken: 1. Apply compiler optimization for size. This can be done in the MCUXpresso by: Opening properties of project. Right Click project-   >Properties Go to Settings->Optimization. For Optimization Level choose “Optimize for Size” Building the project after this step results in a successful build but the project takes up 93% of all Flash, leaving very little space for adding more functionality. 2. The vanilla Basic discovery loop example detects all types of NFC tags. This increases our code size, so further size reduction can be achieved by limiting the number of protocols used. To limit our Basic Discovery loop to only look for Type A tags, do the following: Open the file “ph_NxpBuild_App.h” file which is inside in the “intfs” folder. This file defines the protocols (types) which are detected by the Basic Discovery Loop example. The type A cards uses the “ISO 14443-3A” protocol, so comment out all other protocol definitions except for “ISO 14443-3A” protocol as shown in Figure.   Building the project after this step  takes up only 42.784KB of space consuming 65% of the Flash, leaving sufficient amount of space for adding application code.   Running Basic Discovery Loop on LPC845 If this is the first time you’re using the LPCXpresso845 Max board, follow the getting started guide first ->  LPC845Max | NXP . Make sure to install the SDK package LPCXpresso845 Max which is required for the project below to run. Download the “lpcxpresso845max_Basic_Discovery_Loop” 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 from here: https://www.nxp.com/support/developer-resources/software-development-tools/mcuxpresso-software-and-tools/mcuxpresso-integrated-development-environment-ide:MCUXpresso-IDE ) 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: After step 4, the project should be running now. The output “BasicDiscoveryLoop Example” can be seen in the console. The project contains basic discovery loop functionality. Bring any NFC card near the frontend’s RF antenna and the output console will show the detection and type of the card. Running other examples from NFC Reader Library on LPC845: Once the “lpcxpresso845max_Basic_Discovery_Loop” project is running on the LPC845, running other examples from NFC Reader Library is simple. Here we use the “NfcrdlibEx9_NTagI2C” example from the reader library to describe the process. In “intfs” folder remove everything except the “phaApp_Init.h” file. Then go to the “intfs” folder of the NFC Reader Library example you want to run (“NfcrdlibEx9_NTagI2C” in this case), and copy all the files except “phaApp_Init.h” and paste them in the original “intfs” folder.  I n line 57 of the “ph_NxpBuild_App.h” file in “intfs” folder, replace  Go to “source” folder and remove every file except “phApp_Init.c“ and “semihost_hardfault.c” files. Then go to “src” folder of the example you want to run (“NfcrdlibEx9_NTagI2C” in this case) and copy all the files except “phaApp_Init.c” and paste them into the “source” folder.  Finally, copy the main file of the example you want to run (NfcrdlibEx9_NTagI2C in this case) and paste it into the “source” folder as well. The project is ready to build and run on LPC845. Available Resources: Porting NFC Reader Library to i.MX RT1050.
