Pico GFX Pack MicroPython Examples

About Pico GFX Pack

GFX Pack adds a 128x64 LCD Matrix display to your headered Raspberry Pi Pico or PicoW, with RGBW backlight and 5 input buttons for all your display and control needs.

You'll need to download the most recent version of our MicroPython firmware for your board from the link below.

Pico GFX Pack and PicoGraphics

The easiest way to start displaying cool stuff on GFX Pack is using our GFX Pack helper module (which contains a bunch of useful shortcuts for interacting with the board) and our PicoGraphics display library which handles drawing things on the screen.

Basic Examples

Balls Demo

balls_demo.py

LCD demo with a bunch of bouncy balls!

Button Test

button_test.py

Shows how to read the buttons, display text and change the colour of the RGBW backlight.

Rainbow

rainbow.py

This example borrows a CircuitPython hsv to rgb function to cycle through some rainbows on GFX Pack's screen.

Snake

snake.py

Basic Snake demo for GFX Pack.

  • A = up
  • B = down
  • C = reset
  • D = left
  • E = right

Advanced Examples

These examples require additional hardware. We connected our breakouts using a JST-SH to JST-SH cable:

CO2

co2

Add a SCD41 sensor breakout to your GFX Pack to make a handy CO2 detector! Press A to reset the high/low values.

Thermometer

thermometer.py

This demo uses a BME680 or BME688 breakout to measure temperature, pressure, and humidity and display it on the GFX display.

To use the Pico's internal temperature sensor in place of the BME68x breakout, just change use_bme68x_breakout to False.
