STM32CubeIDE HAL_I2C_ErrorCallback function does not work.

[Ade J.3]

I'm using i2c interface to communicate with a eeprom memory, by dma.

It's working, however, when I put a wrong address to write in the memory (to test the errors), I get as return HAL_ERROR, but the function HAL_I2C_ErrorCallback (that i implemented) does not called.

How can I get a callback from this function in a error situation?

Part of my code is available below:

status = HAL_I2C_Mem_Write(&hi2c3, 0xB4, (0<<8), 2, dataWrite, 270, 1000); //Wrong Address
 
void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c){
		HAL_UART_Transmit(&huart1, errorMsg, sizeof(errorMsg), 1000);
}

Hello @Ade J.3​ ,

You can try to set this function :

/* USER CODE BEGIN 2 */
if (HAL_I2C_Mem_Write(&hi2c3, 0xB4, (0<<8), 2, dataWrite, 270, 1000) != HAL_OK)
 {
 Error_Handler();
 }
/* USER CODE END 2 */

and :

/* USER CODE BEGIN 4 */
void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c)
{
HAL_UART_Transmit(&huart1, errorMsg, sizeof(errorMsg), 1000);
}
/* USER CODE END 4 */

Thank you for the answer. That worked for me!

However, it isn't using DMA. Is there any way to get the callback with transmission by DMA?
