    Hallo zusammen,

    da ich weiß das dieser Artikel recht beliebt ist, wollen wir den heute mal aktualisieren. Vieles aus den vorherigen Beiträgen passt noch. Es gibt aber kleine Anpassungen.

    Hardware ROCKPro64v21. 2GB RAM Software Kamils Release 0.10.9 Linux rockpro64 5.6.0-1132-ayufan-g81043e6e109a #ayufan SMP Tue Apr 7 10:07:35 UTC 2020 aarch64 GNU/Linux Installation apt install python

    Danach laden wir das Projekt

    git clone https://github.com/Leapo/Rock64-R64.GPIO

    PIN Nummern anpassen

    cd Rock64-R64.GPIO/R64 nano _GPIO.py

    Datei ergänzen

    Bild Text

    Wenn der Taster im Bild betätigt wird, soll die LED blinken.

    Wir benutzen folgende Ein- Augänge des ROCKPro64.

    # Set Variables var_gpio_out = 156 var_gpio_in = 155

    Das heißt:

    an Pin 1 (3,3V) kommt eine Strippe des Tasters an Pin 29 (Input) kommt eine Strippe des Tasters an Pin 31 (Output) kommt der Plus-Pol der LED an Pin 39 (GND) kommt der Minus-Pol der LED

    Somit wird auf den Eingang (Pin 29) bei Betätigung des Tasters 3,3 Volt angelegt. Damit wird dann der Eingang als High (1) erkannt. Die LED wird über den Ausgang (Pin 31) gesteuert.

    Starten kann man das Script mit

    python test.py

    Mein gekürztes Ergebnis auf einem ROCKPro64 v2.0 mit 4GB RAM und 4.18er Kernel, dieser ROCK benutzt eine SD-Karte!
