I have implemented the following code based on some examples on internet. It is supposed to trigger the DMA transfer complete callback put it does not. 99% of the code is generated using CubeMX IDE.
The modified part of the code:
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
HAL_GPIO_TogglePin(GPIOA, LD2_Pin);
}
/* USER CODE END 0 */
/**
* @brief The application entry point.
* @retval int
*/
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_USART2_UART_Init();
MX_DMA_Init();
/* USER CODE BEGIN 2 */
uint8_t pData[16];
HAL_UART_Receive_DMA(&huart2, pData, 16);
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
Autogenerated DMA init:
static void MX_DMA_Init(void)
{
/* DMA controller clock enable */
__HAL_RCC_DMA1_CLK_ENABLE();
/* DMA interrupt init */
/* DMA1_Channel6_IRQn interrupt configuration */
HAL_NVIC_SetPriority(DMA1_Channel6_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(DMA1_Channel6_IRQn);
}
What Im I doing wrong? The code I generate is basically the same as in examples across internet. I have a nuceo-L476RG board. Below is the CubeMX project attached:
