Adafruit Install

• https://circuitpython.org/board/raspberry_pi_pico/
• https://downloads.circuitpython.org/bin/raspberry_pi_pico/de_DE/adafruit-circuitpython-raspberry_pi_pico-de_DE-7.0.0.uf2

Copy File

• cp ~/Download/adafruit-circuitpython-raspberry_pi_pico-de_DE-7.0.0.uf2 .

Nach ein paar Sekunden wird eine "USB-Stick" mit dem Namen "CIRCUITPY" gemountet

Script

• Damit der Payload bearbeitet werden kann, muss PIN 15 mit GND verbunden werden
• Wenn PIN 15 nicht mit GND verbunden ist, wird das Filesystem nicht gemountet

Deutsches "Tastertur" Layout Einfügen

• Das vornstallierte Englische Layout und die Keycodes müssen ersetzt werden
• Verschieden Sprachen findet man in der Git Repo
