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.

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
This post contains step by step guide of how to use NTAG I²C plus with i.MX RT MCUs. The goal of this post is to enable developers to start developing their NFC Applications using NTAG I²C plus and i.MX RT MCUs quickly and easily. Attached with this post are two ready to use packages: ‘evkbimxrt1060_ntagI2C’ is to be used with MIMXRT1060-EVK and NTAG I²C plus kit for Arduino pinout. ‘evkbimxrt1050_ntagI2C’ is to be used with MIMXRT1050-EVK and NTAG I²C plus kit for Arduino pinout. Both packages contain the same example code but are configured for the two different boards. The example code demonstrates the following basic operations: Reading the EEPROM of NTAG I²C plus. Writing NTAG messages to NTAG I²C plus. Reading SRAM of NTAG I²C plus. Writing to SRAM of NTAG I²C plus. Using Field detect pin as interrupt to turn on an LED when an RF field is detected by the NTAG I²C board. The document has been structured as follows: NTAG I²C plus kit for Arduino pinout The NTAG I²C plus Arduino kit consist of two PCBs stacked together: The upper PCB is the antenna board with the connected tag The lower PCB is an interface adaptor board to the Arduino pinout This kit can be used to connect and evaluate the NTAG I²C plus into many popular MCUs with Arduino compliant headers, for example: Kinetis (e.g. KW41Z, i.MX (e.g. UDOO Neo, i.MX 6UL, i.MX 6 ULL, i.MX 7D), LPC MCUs (e.g. LPCXpresso MAX, V2 and V3 boards) and i.MX RT boards (e.g. i.MX RT1050, i.MX RT1060) The kit support package includes several software examples. The OM29110ARD is a generic interface board which offers support for connection to any PCB implementing Arduino connectors. It exposes: 3.3V and 5V power supply pins. I2C, SPI and UART host interfaces. Generic GPIOs (e.g. to be used for field detect, interrupts, reset pins or others) As such, it allows the NTAG I²C plus to be plugged into Arduino devices seamlessly. Hardware Requirements EVKB-IMXRT1050 board or EVKB-IMXRT1060 board. NTAG I²C plus kit for Arduino pinout (OM23221ARD) Cables: Micro USB cable 6 jumper wires Male to Female (Only required if using EVKB-IMXRT1050 board) Using NTAG I²C plus kit for Arduino pinout with EVKB-IMXRT1060 Hardware Connections The hardware connections are simple. Both the EVKB-IMXRT1060 board and OM23221ARD (NTAG I²C plus) board have Arduino interface. So simply connect both as shown in figure: Running the Demo Follow the below mentioned steps to run the demo: Download the ‘evkbimxrt1060_ntagI2C’ package which you will find attached to this post. Drag and drop the downloaded package to 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, 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: Note: If this is your first time using IMXRT1060EVK board, it is recommended to follow the getting started guide first ( i.MX RT1060 Evaluation Kit | NXP ) To see the output, you need to have a terminal application installed (like Tera term or PuTTY). The output looks like this: Using NTAG I²C plus kit for Arduino pinout with EVKB-IMXRT1050 Hardware Connections In case of EVKB-IMXRT1050, the I2C pins on the Arduino interface’s J24 pin 9 and 10 are only connected to the i.MX RT slave I²C port, not to a master I²C port. So, we cannot just plug in the NTAG I²C plus kit, instead we need to connect two boards with the help of jumper wires. The connections required are show in figure below. Running the Demo Download the ‘evkbimxrt1050_ntagI2C’ package which you will find attached to this post. Drag and drop the downloaded package to 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, 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: Note: If this is your first time using IMXRT1050EVK board, it is recommended to follow the getting started guide first ( i.MX RT1050 Evaluation Kit | NXP ) To see the output, you need to have a terminal application installed (like Tera term or PuTTY). The output looks like this: Porting the Package to any other i.MX RT Boards If you want to use NTAG I²C plus with i.MX RT boards other than the i.MX RT1050 or the i.MX RT1060, then you’ve to port the example package. This is fairly straightforward and the procedure is described below: Import the ‘hello world’ project from the SDK of the board to which you want to port the package. (SDKs for every board are freely available for download from the MCUXpresso SDK Builder website).We will modify this ‘hello world’ project adding code from attached packages, to make it work on the desired board. Copy the following folders from the attached ‘evkbimxrt1060_ntagI2C’ or ‘evkbimxrt1050_ntagI2C’ package to the ‘hello world’ project imported in step 1: Copy the two files to the ‘drivers’ folder of ‘hello world’ project: Delete the ‘hello_world.c’ file from the source folder: Now copy the following preprocessor micros from ‘evkbimxrt1060_ntagI2C’ or ‘evkbimxrt1050_ntagI2C’ package to ‘hello world’ project: Preprocessor settings can be found by right clicking Project-Properties>C++Build > Settings Now we need to change the project configuration: a. Add the newly copied folders to source location; Right click on Project->Properties and add the following folders: b. Include paths to the added libraries in the project. These can be copied from the from ‘evkbimxrt1060_ntagI2C’ or ‘evkbimxrt1050_ntagI2C’ package. Open project->properties and copy the following in the respective places as shown in the images: Change pin configurations according to the board pins you are using: a. For changing field detect pin, the code can be found in the source file: b. For I2C instance, the lines of code are in app_ntag->app_ntag.h: c. These pins also need to be initialized which can be done through the pin initialization tool of MCUXpresso or code can be added to the ‘board.c’ file in ‘board’ folder. Once these changes are done, porting is complete. Build the project, it should build without any errors.

As NFC reader library 5.12 also supports PN5180, switching the NFC frontend from CLRC663 to PN5180 is quite easy based on previous porting. The porting also includes the hardware settings and software modification. Hardware Setup for porting: a) Remove resistors on PNEV5180B to disconnect the onboard lpc1769 from PN5180, following steps on page 16 of https://www.nxp.com/docs/en/application-note/AN11908.pdf b) Connect LPCXpresso board for LPC11U37 with PNEV5180 as below: Software Modification for porting: 1. Make a copy of Board_Lpc11u37Rc663.h , and change its name to "Board_Lpc11u37Pn5180.h", and import it into the DAL/boards folder. 2.Change the source code in the header file as below: 3. Add two more pins' definition and configuration for BUSY and DWL pins of PN5180, and new configuration for reset pin. and modify the reset logic: 4.Change the IRQ interrupt trigger type to rising edge. 5.Include this header file in BoardSelection.h 6.Add this new configuration in ph_NxpBuild_App.h 7.Add this new configuration in phApp_Init.h 8.Add this new configuration in ph_NxpBuild_Platform.h 9.Add this new configuration in Settings. 10.Building result: Testing result:

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:
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...
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.
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. S tart MCUXpresso IDE and i mport any LPC1769 project from filesystem. For example: SW3522.zip. T his 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_v126.96.36.199\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 v188.8.131.52. 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_v184.108.40.206\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.
