Für die Ansteuerung des LCD wird `rpi-pico-i2c-lcd` von _T-622_ ([Github](https://github.com/t-622/rpi-pico-i2c-lcd)) verwendet, das wiederum auf `python_lcd` von _dhylands_ ([Github](https://github.com/dhylands/python_lcd)) basiert. Letzteres steht unter der MIT-Lizenz. `rpi-pico-i2c-lcd` ist ohne Lizenzangabe. Die entspechenden Dateien liegen der Einfachheit halber im `lib` Unterverzeichnis.
### Installation
Am einfachsten ist es, mittels [Thonny](https://thonny.org/) die Datei `main.py` sowie den `lib`-Ordner ins Hauptverzichnis des Picos zu kopieren. Auf dem Pico muss natürlich MicroPython installiert sein. Fertig.
