I just worked through all the examples in the RedBoard Trubo Hookup Guide. Everything went well except the Serial Ports demo did not echo the text entered in the Serial Monitor (see attachment).
I’m running Windows 10 Pro and Arduino 1.8.13 (Windows Store 1.8.42.0).
Can you please provide a picture of your setup?
Are you printing any non-printable characters after “Hello”? Or are you typing in “Hello” and hitting send?
I’m typing Hello and hitting Enter.
To confirm, you’re using just the example code from the hookup guide?
That is correct, I’m just using the example code from the hookup guide.
Are you able to connect any sensors via UART to see if the serial lines are not working? I would suspect that their could be a soldering issue on the pins for the UART lines. Are you able to take a detailed picture of the SAMD21 IC on the board and the TX/RX header pins?
