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 */
How are you testing it?
Does the transmit work?
What debugging have you done on your hardware?
Have you tried provided examples on known-good hardware?
