HAL_UART_Receive_IT timeout

Hi everyone,

I have the same question as Steven, so if somebody know how to achieve the timeout in interrupt uart reception, please help us.

Thanks,

Joris

The above code seems to totally misunderstand the concept of using an interrupt and callbacks. Grinding in a loop and blocking seems to miss the point.

If you use HAL_UART_Receive_IT() in this way you need to use HAL_Ticks() to evaluate if the timeout expires, or use the HAL_UART_Receive() form. For Tasks have a semaphore that gets set on successful UART callback, or on a TIM/SysTick based timeout.

Also if the mechanics of the HAL, and the USART stack don't fit the paradigm of your existing code/methodology you are at liberty to implement something better.
