Ich stelle mich grad ziemlich blöd an, ich versuche ein Programm zu erstellen das die Werte eines Analog Joysticks und die Werte eines Encoders ausliest.
Jeweils einzeln habe ich diese Programme schon und sie Funktionieren. Doch sobald ich diese zusammenfüge kriege ich bei mir immer das reinste chaos raus. Entweder es gibt mir immer nur die werte von einem Bauteil raus oder der Raspi hängt sich auf.
ich bin auch für Tipps dankbar.
Gruss Dani
Das Encoder Programm ist von: https://www.sunfounder.com/learn/Super_ ... rrypi.html
Das Joystick Programm ist von: https://www.raspberrypi-spy.co.uk/2014/ ... n-mcp3008/

Zu guter letzte Mein selbst erstellter Code:
Meine Gedanken dazu:
Ich Held hab einen ewig langen Text geschrieben und dann ausversehentlich alles gelöscht... kurz zusammengefasst Mein gedanke war wenn ich die beiden While True Schleifen der Beiden Programme zusammenfüge so arbeiten sich beide Programme ab und geben mir sowohl Encoder als auch Joystick Werte aus bis in alle Ewigkeit.
In Wirklichkeit aber hängt sich der Pi fasst auf und gibt verzögert nur die joystick werte.

), außerdem ist python nicht so mein Ding. Kanns zwar lesen aber is wie mit ner Fremdsprache die man nicht so gut kann
