This example demonstrates the use of a UART port in loopback mode. On being enabled in loopback mode, the transmit line of the UART is internally connected to its own receive line. Hence, the UART port receives back the entire data it transmitted. This example echoes data sent to the UART's transmit FIFO back to the same UART's receive FIFO. To achieve this, the UART is configured in loopback mode. In the loopback mode, the Tx line of the UART is directly connected to its Rx line internally and all the data placed in the transmit buffer is internally transmitted to the Receive buffer. This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board. - UART7 peripheral - For internal Loopback - UART0 peripheral - As console to display debug messages. - UART0RX - PA0 - UART0TX - PA1 UART parameters for the UART0 and UART7 port: - Baud rate - 115,200 - 8-N-1 operation
