How can I connect STM32G071 board with ST25R3911B chip (X-NUCLEO-NFC05A1)?

[EElec.2]

Hello there, STM32 community!

I am new to the STM32 family and I am currently working on a project to read and write Mifare Classic and Desfire tags. For this, I am using an STM32G071-NUCLEO64 microcontroller and a X-NUCLEO-NFC05A1 (ST25R3911B) board connected via SPI. I have been trying to establish the SPI connection between the two devices and send/receive data, but so far, I have not been successful.

Initially, I tried to use the SPI example provided in STM32CubeIDE, but I was not able to receive data correctly.

Then, I followed a post on the ST community website to use the RFAL/NDEF libraries for my project. However, the post was for the 32f070RB board, and I had to make some modifications to make it work with my hardware.

Unfortunately, after copying the RFAL and NDEF libraries into my project, modifying the platform.h file, and adding the necessary modules, I am still unable to get it working.

The error I am receiving is:

#define ERR_HW_MISMATCH ((ReturnCode)36U) /*!< expected hw do not match */

after executing rfalNfcInitialize().

I am feeling lost and unable to find a suitable example for my specific case.

Can someone please guide me on how to initialize the connection between the STM32G071 and the ST25R3911B chip?

What is the best way to receive data and work with it?

Thank you very much for your time and help!

Coud you share your code or some links to ST example?

[EElec.2]

Hello, yea!

My main function in main.c is like this:

int main(void)
{
  /* USER CODE BEGIN 1 */
 
  /* USER CODE END 1 */
 
  /* MCU Configuration--------------------------------------------------------*/
 
  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();
 
  /* USER CODE BEGIN Init */
 
  /* USER CODE END Init */
 
  /* Configure the system clock */
  SystemClock_Config();
 
  /* USER CODE BEGIN SysInit */
 
  /* USER CODE END SysInit */
 
  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_SPI1_Init();
  MX_USART1_UART_Init();
  /* USER CODE BEGIN 2 */
 
  spiInit(&hspi1);			// Initialize driver
  logUsartInit(&huart1);	// Initialize log module
 
  platformLog("Welcome to X-NUCLEO-NFC05A1\r\n");
 
 
  /* Initalize RFAL */
  if( !demoIni() )
  {
    /*
    * in case the rfal initalization failed signal it by flashing all LED
    * and stoping all operations
    */
    platformLog("Initialization failed..\r\n");
    while(1)
    {
      platformLedToogle(PLATFORM_LEDG_PORT, PLATFORM_LEDG_PIN);
      platformDelay(100);
    }
  }
 
	platformLog("Initialization succeeded..\r\n");
	for (int i = 0; i < 6; i++)
	{
		platformLedToogle(PLATFORM_LEDG_PORT, PLATFORM_LEDG_PIN);
		platformDelay(200);
	}
 
	platformLedOff(PLATFORM_LEDG_PORT, PLATFORM_LEDG_PIN);
 
 
  /* USER CODE END 2 */
 
  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
	/* Run Demo Application */
	demoCycle();
 
    /* USER CODE END WHILE */
 
    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

and the rest of project it's almost an exact copy of the the one you can donwload here: https://www.st.com/en/embedded-software/x-cube-nfc5.html#get-software

And in the first question, I add a link in the words "post on the ST community website" but in case it is not working, the link to the post I followed is: https://community.st.com/s/question/0D53W000006G1H9SAK/how-to-start-with-st25r3911b-and-is-it-really-necessary-to-use-rfal-and-st25r3911-libraries-for-simpel-project

Thanks!

Probably some wrong in your modified code (platform.h). coud you share file? What files did you change ?

[EElec.2]

Of course.

This is my platform.h. And the only files that I changed are the platform.h and the main.c.

You will see that there are "UNKOWN_PIN and UNKOWN_PORT" that's because I don't need those PORT-PINS and I assigned a random one...

[Kamil Duljas]

OK, so show also main.c 🙂

So if you modified only these two files, where is the initalization GPIO for SPI? B0 and B4?

Perhaps instead of changing platform.h you should changing main.h? I think main.h is more board specific than platform.h

[EElec.2]

It makes sense...

So, I init them like this:

static void MX_GPIO_Init(void)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
/* USER CODE BEGIN MX_GPIO_Init_1 */
/* USER CODE END MX_GPIO_Init_1 */
 
  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();
  __HAL_RCC_GPIOB_CLK_ENABLE();
 
  /*Configure GPIO pin Output Level */
  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0|GPIO_PIN_4, GPIO_PIN_RESET);
 
  /*Configure GPIO pin : PC13 */
  GPIO_InitStruct.Pin = GPIO_PIN_13;
  GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
 
  /*Configure GPIO pin : PB0 */
  GPIO_InitStruct.Pin = GPIO_PIN_0;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
 
  /*Configure GPIO pin : PB4 */
  GPIO_InitStruct.Pin = GPIO_PIN_4;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_PULLDOWN;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
 
  /* EXTI interrupt init*/
  HAL_NVIC_SetPriority(EXTI4_15_IRQn, 0, 0);
  HAL_NVIC_EnableIRQ(EXTI4_15_IRQn);
 
/* USER CODE BEGIN MX_GPIO_Init_2 */
/* USER CODE END MX_GPIO_Init_2 */
}

configured using the visual interface of STM32CubeIDE so I can't mess it up hahaha

But anyways, the error code is still the 36 (ERR_HW_MISMATCH) mentioned earlier...

[Kamil Duljas]

Yours PB4 that repleace IRQ_3911_Pin is wrong:

/*Configure GPIO pin : PB4 */

GPIO_InitStruct.Pin = GPIO_PIN_4;

GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;

GPIO_InitStruct.Pull = GPIO_PULLDOWN;

GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;

HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

 /*Configure GPIO pin : IRQ_3911_Pin */

 GPIO_InitStruct.Pin = IRQ_3911_Pin;

 GPIO_InitStruct.Mode = GPIO_MODE_IT_RISING;

 GPIO_InitStruct.Pull = GPIO_NOPULL;

 HAL_GPIO_Init(IRQ_3911_GPIO_Port, &GPIO_InitStruct);

My advice. Undo all changes. Start from beginning and change only main.h:

```
