usart_transfer_interrupt#
Overview#
The usart_interrupt example shows how to use usart transactional API in interrupt way:
In this example, one usart instance connect to PC through, the board will send back all characters that PC send to the board.
Note: The example echo every 8 characters, so input 8 characters every time.
