Overview

The uart-echo command shows the ReadWriter interface implementation of the CH347 UART by doing a simple echo test.

How to test on linux:

1. Connect your other USB TTL as follows:

   - CH347 UART1 USB to TTL converter

   - TX -> RX

   - RX -> TX

   - GND -> GND

2. On the first terminal, set baud rate and start reading to see the input:

   stty -F /dev/ttyUSB0 115200 -echo

   cat /dev/ttyUSB0

3. Start echo example with `go run` etc.

4. On the second terminal, send whatever you like to be seen on your first terminal:

   echo "Whatever" > /dev/ttyUSB0
