Hi,
I'm currently programming on the board F446RE with STM32CubeIDE, I'm only trying to get an array from the UART but I'm quite block.
When I send an array with my computer only the first byte is sent and update in my array on the STM32. While I'm following the instruction from this youtube video: https://www.youtube.com/watch?v=xE6GVt7XuJI.
Currently my code look like this:
Here is my UART configuration:
------------------------------------------------------------------------------------------------------
static void MX_USART2_UART_Init(void)
{
/* USER CODE BEGIN USART2_Init 0 */
/* USER CODE END USART2_Init 0 */
/* USER CODE BEGIN USART2_Init 1 */
/* USER CODE END USART2_Init 1 */
huart2.Instance = USART2;
huart2.Init.BaudRate = 115200;
huart2.Init.WordLength = UART_WORDLENGTH_8B;
huart2.Init.StopBits = UART_STOPBITS_1;
huart2.Init.Parity = UART_PARITY_NONE;
huart2.Init.Mode = UART_MODE_TX_RX;
huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart2.Init.OverSampling = UART_OVERSAMPLING_16;
if (HAL_UART_Init(&huart2) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USART2_Init 2 */
/* USER CODE END USART2_Init 2 */
}
-----------------------------------------------------------------------------------------------------
Here my Callback functions
-----------------------------------------------------------------------------------------------------
/* USER CODE BEGIN 4 */
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
HAL_UART_Receive_IT(&huart2, rx_buff, 5);
__NOP();
}
void HAL_UART_TxCpltCallback(UART_HandleTypeDef *huart)
{
__NOP();
}
void HAL_UART_ErrorCallback(UART_HandleTypeDef *huart)
{
__NOP();
}
/* USER CODE END 4 */
--------------------------------------------------------------------------------------------------------
Here my main:
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();
/* USER CODE BEGIN 2 */
//HAL_UART_Transmit_IT(&huart2, mess, 20);
HAL_UART_Receive_IT(&huart2, rx_buff, 5);
HAL_UART_Transmit_IT(&huart2, tx_buff, 5);
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5);
HAL_Delay(500);
}
/* USER CODE END 3 */
}
--------------------------------------------------------------------------------------------------------
To send the UART array I use the python's code
--------------------------------------------------------------------------------------------------------
import serial
#Test un envoie sur l'interruption
ser = serial.Serial("/dev/ttyACM0", baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=500)
array = bytearray([8,2,3,4,5])
ser.write(array) #Envoie sur le port UART
--------------------------------------------------------------------------------------------------------
Could you help me please? :(
Sincerely yours,
Julien
