Hello,
I'm having some issue with the usart, everything works just fine, but if I start querying the usart with a bad baud rate and especially when the stop bits setting is incorrect, then the mcu hangs after couple of seconds. Please look below, I have tried to reset all the flags, but it still has not any positive effect.
void HAL_UART_ErrorCallback(UART_HandleTypeDef *huart) {
if (huart->Instance == USART6) //check if error from MODBUS USART
{
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_ORE);
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_FE);
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_PE);
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_NE);
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_RXNE);
__HAL_UART_CLEAR_FLAG(&huart6, UART_FLAG_TXE);
__HAL_UART_CLEAR_FEFLAG(&huart6);
__HAL_UART_CLEAR_NEFLAG(&huart6);
__HAL_UART_CLEAR_OREFLAG(&huart6);
__HAL_UART_CLEAR_PEFLAG(&huart6);
__HAL_UART_FLUSH_DRREGISTER(&huart6);
//HAL_DMA_GetError(DMA1_Stream1);
//HAL_DMA_CleanCallbacks(DMA1_Stream1);
HAL_UART_DMAStop(&huart6);
HAL_UART_Receive_DMA(&huart6, &MODBUS_Rx_data, 1);
Thanks for any tips,
BR
