Hallo,
ich habe ein Problem beim kompilieren eines alten Programmes.
D.h. das ich das Pogramm mit einer älteren Version kompilieren konnte.
Leider weiss ich nicht die entsprechenden Versionen.
Im Moment verwende ich folgende Versionen:
Arduino Version 2.3.2
ESP32-Boards 3.2
Lib’s siehe Programm-Code
