Hi..,
Ds code not working receive NULL value kindly help me I'm using STM32H750VB
/* USER CODE END WHILE */ HAL_UART_Transmit(&huart2,recdata,sizeof(recdata),1000); HAL_Delay(100); HAL_UART_Receive(&huart2,recdata,sizeof(recdata),1000); /* USER CODE BEGIN 3 */
Does it return errors?
These are blocking functions, the receive runs AFTER the transmit, and not going to capture data you put on the wire in the PAST
