The T-Deck has a 4-pin JST connector on the right-hand side of the back of the board, with connections RX, TX, VCC, and GND. Has anyone figured out how to use this with with-serial for serial input and output?
I got it to work but I’m not sure if its exactly what you expect. I followed this guide, basically you have to add
#include <HardwareSerial.h> HardwareSerial SerialPort(2); //you can name this something else
Then change the serialbegin function from
SerialPort.begin((long)baud*100, SERIAL_8N1, RX, TX);
and then replace all instances of Serial1 with SerialPort.
I haven’t tested this extensively but I got some bits on the FTDI cable. I can make you a pull request later if you want
Great! I’ll try it.
