Hallo liebes Forum,
ich habe einen Nano 33 IOT an welchem ein RFID Reader angeschlossen ist und mit der MFRC522 Bibliothek funktionert.
Leider hört der Reader manchmal einfach auf Karten zu lesen (manchmal nach ner halben Stunde manchmal von Beginn an) ich kann das Problem nicht ganz einordnen.
Die Loop an sich in der das Programm läuft funktioniert noch nur passiert absolut nichts wenn man eine Karte auf den Reader legt (egal welche).
Vielleicht habt ihr ja eine Idee wie ich das Problem eingrenzen/reproduzieren könnte oder woran es liegen kann.
Anbei ist mein Programm Code.
Viele Grüße Alex
