This software contains high performance NFC reader/initiator front-end IC drivers for the ST25R300 device, running on STM32. It is built on top of STM32Cube software technology to ease portability across different STM32 microcontrollers.
This firmware package includes component device drivers, a board support package, and a sample application demonstrating usage of the X-NUCLEO-NFC12A1 expansion board with STM32 Nucleo boards.
A sample application configures the ST25R300 in a polling loop for active and passive device detection. When a passive tag or active device is detected, the reader field signals the detected technology by switching a corresponding LED on. It is also possible to set the ST25R300 in an inductive wake-up mode by pressing the user button. During this polling loop, the sample application also sets the ST25R300 in card emulation mode to detect the presence of a reader.
The demo logs all activities to the host the system with ST-LINK virtual COM port.

Faaji
This fully compliant software expansion for STM32Cube lets you develop applications using the ST25R300 high performance NFC reader/initiator IC. It is based on the STM32CubeHAL hardware abstraction layer for the STM32 microcontroller, and it extends STM32Cube with a board support package (BSP) for the X-NUCLEONFC12A1 expansion board.
Application software can access and use the X-NUCLEO-NFC12A1 expansion board through the following layers:
·
STM32Cube HAL layer: the HAL driver layer provides a simple set of generic, multi-instance application
programming interfaces (APIs) to interact with the upper layers (application, libraries, and stacks). These
generic and extension APIs are directly built on a common architecture and allow overlying layers like
middleware to implement their functions without depending on specific microcontroller unit (MCU) hardware
information. This structure improves the library code reusability and guarantees easy portability across
awọn ẹrọ miiran.
·
Board support package (BSP) layer: the BSP provides support for the peripherals on the STM32 Nucleo
board, apart from the MCU. This set of APIs provides a programming interface for certain board-specific
peripherals like the LED, the user button etc. This interface also helps you identify the specific board
ti ikede.
·
Middleware NRF abstraction layer (RFAL): the RFAL provides several functions for RF/NFC
communication. It possesses RF IC (existing ST25R300 device) under a common and easy to use
ni wiwo.
Awọn ilana ti RFAL pese ni:

ISO-DEP (ISO14443-4 data link layer, T = CL).
·
NFC-DEP (ISO18092 data exchange protocol).

·
P2PISO18092 (NFCIP1, Passive-Active P2P).
·

Internally, the RFAL is divided into three sub layers:
·
RF higher layer (RF HL).
·
RF hardware abstraction layer (RF HAL).
·
RF abstraction layer (RF AL).
olusin 1. RFAL Àkọsílẹ aworan atọka
The modules in the RF HAL are chip-dependent. They implement the RF IC driver, configuration tables, and specific instructions for the HW to perform the physical RF functions.
The interface for the caller is a shared RF header file, which provides the same interface for upper layers (for all chips).
The RFAL can be broken down into two further sub layers:
·
Technologies: technology modules which implement all the specifics, framing, timings, etc.
·
Awọn Ilana: imuse ilana pẹlu gbogbo awọn fireemu, awọn akoko, mimu aṣiṣe, ati bẹbẹ lọ.
On top of these, the application layer uses RFAL functions like NFC Forum Activities (NFCC), EMVCo®, DISCO/ NUCLEO demo, etc.
The RFAL NFC module provides an interface to perform the common activities as poller/listener device.
Access to the lowest functions of the ICs is granted by the RF module. The caller can make direct use of any of the RF technology or protocol layers without requiring any specific hardware configuration data.

Sample elo
A sample application using the X-NUCLEO-NFC12A1 expansion board with the NUCLEO-L476RG, NUCLEOG0B1RE or NUCLEO-C071RB development board is provided in the “Projects” directory. Ready-to-build projects are available for multiple IDEs.
In this application, NFC tags of different types are detected by the ST25R300 high performance NFC reader/ initiator front-end IC (for further details, refer to the CHM documentation file generated from the source code).
After system initialization and clock configuration, LED1, LED2, LED3, LED4, LED5, and LED6 blink three times. Then LED6 glows to indicate the reader field has been activated.
Nigbati a tag is detected in proximity, an LED is switched on as listed below.
NFC tag type NFC TYPE A NFC TYPE B NFC TYPE V NFC TYPE F
Table 2. LED lit on tag detection LED lit on tag detection LED2/Type A LED3/Type B LED4/Type V LED5/Type F
If a reader approaches the X-NUCLEO-NFC12A1 expansion board, the software enters into card emulation mode and, depending on the command type sent, it switches the respective NFC TYPE LED on. By default, the X-NUCLEO-NFC12A1 does not write any data to the tag, but this possibility can be enabled by a preprocessor defined in the file demo.h. Card emulation and poller mode can also be enabled/disabled with the same procedure. The ST virtual communication port interface is also included in the package. Once the board is powered on, the board is initialized and enumerated as ST-LST-LINK virtual COM port.
