General Discussion / Serial communication with TinyScreen+
« on: May 16, 2023, 11:29:03 PM »
Good Day guys I got some questions about the serial communication.

I understand that the USB serial and the Serial on the board are separate ports as if I want to see some info on the serial monitor on the screen I have to use SerialUSB. print ("something") but how can I use the TX and RX on the board? how should I call them? also what is the voltage that I need? I know arduino is 5v on the logic levels but not sure about Tiny Screen+, I got a project where I have to connect a ESP32 Feather to a TinyScreen+ and the Feather works with 3.3v levels.

I'm a bit lost and will appreciate all the help in this matter.
