Hi all


I'd like to use UART to receive soe fixed length datas, ex."1234567890".

uint8_t buff[10]; 

hal_uart_receive_it(&huart, buff, 10); or hal_uart_receive_dma(&huart, buff, 10);


How should I do and then make sure the buff contain "1234567890" every time, not "5678901234" or other situation.

Thank you in advance.
