Presented here is a straightforward UART echo Rust example utilizing Martos with UART functionality.
Within the setup function, the UART interface is initialized once on GPIO pins 16 (RX) and 17 (TX) with 19200 baud rate, 8 data bits, no parity, and 1 stop bit. Additionally, within the loop function, incoming UART data is continuously read byte-by-byte and immediately echoed back to the sender, with each processed byte being logged along with a running counter for debugging purposes.
