https://github.com/technoblogy/ulisp-tdeck is the offical version, I'm keeping my repo up for historical reasons and possibly further experiements

Attempt at getting ulisp running on the Lilygo T-Deck

Modified pserial and gserial functions such that the terminal is mirrored on the t-deck display and the t-deck keyboard types to the terminal. No scrolling yet and backspacing doesnt work on newlines, but is otherwise vaguely usable.

The T-Deck repo contains instructions for how to upload code with the arduino IDE

I used the Arduino gfx library instead of the adafruit one because the T-Deck repo examples had it working.

The second I2C port (Wire1) is routed to pins SDA -> 18 and SCL -> 8 and is dedicated to the keyboard

Some t-decks have their screen colors inverted depending on the hardware? (The example code that comes with it asks you to check inversion)
