WebMay 20, 2016 · Firstly, tx_timeout is 0 and most code examples are non-zero. I do not know the side effect. Secondly, HAL_UART_Transmit () is a blocking call and it is not advisable to use blocking calls inside an interrupt. So, I decided to use an interrupt for uart transmission HAL_UART_Transmit_IT () instead of a blocking call. Here is the modified code; WebNov 29, 2024 · HAL UART HAL_UART_Receive Timeout.
