(Using Adafruit ESP32-S3 Reverse TFT Feather.)
This repository provides the code needed to implement a gadget sporting a small TFT display, enclosed in a 3D-printed case, and driven by a program running on your computer (in Python, developed and tested on Linux).
It provides apps like performance monitors, games and various demos, and is extensible.
The Adafruit ESP32-S3 Reverse TFT Feather is an awesome little board consisting of an ESP32-based Arduino and a 240x135 color TFT display on the back side. See https://www.adafruit.com/product/5345.
Wanting first to get one, then to do something with it, I first implemented an external CPU and network monitor gadget for my computer. Quickly impressed by the TFT quality, I ended up implementing various neat apps:
- Performance monitors for local or remote computers
- Asteriod game
- Particles physics simulation
- 3D cube
and others.
A 3D-printed case and cap, designed in OpenSCAD.
An Arduino sketch, implementing a graphical server running on the board and providing TFT graphical primitives, and buttons readout.
It has been successfully built and uploaded using VS Code, see
README-VSCODE.md.
A Python program running on Linux and communicating with the board over USB, implementing various apps:
- asteriods
- bubbles-air
- bubbles-soap
- collisions-elastic
- collisions-gravity
- cube
- fill
- monitor-cpus
- monitor-graph
- monitor-host
- quix
- starfield
- tunnel
To run it, do:
cd client-py
./run.py -h
To create a new app, study app/quix.py, create a new module and
class, and register your new class in run.py.

- Communication protocol between the computer and the board.
- Animations techniques to avoid flicker, in the absence of hardware double-buffering.
