## 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.

## 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.

||
|
|

|
||
|
|
- [PicoGraphics function reference](../../modules/picographics/README.md)

||
|
|
## Basic Examples

|
|
|
||

|
|
[rainbow.py](rainbow.py)
|
||
|
|
|

|
|
|
||
|
|

||
|
|
|

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

### CO2
|
||
|
|
|
||
|
|
[co2](co2.py)
|
||
|
|
|
||
|
|
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](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`.
