Dear Friends,

I want to get an interrupt by receiving each character on UART port. How can I use HAL_UART_Receive_IT() and HAL_UART_RxCpltCallback() functions? When I call HAL_UART_Receive_IT() function its call USART1_IRQHandler I want to know is it a correct approach to call HAL_UART_Receive_IT() function before each receiving character?
