Finally i updated my project to a version with a SD-Card config file for Wifi-Settings and coinpars, colors, etc.
Now if you don't want to compile on your own you can load the precompiled .bin file with populair SD-Menu Loader App and get around all the hardcoding in Arduino-IDE with all the librarys and esp32 board manager..
all you need is to flash my .bin and have a sd card with a folder in root called "ccticker" which holds the file "ccticker.cfg" and the "data" folder for the graphic files.
I do not use SPIFFS memory anymore because it is easier without for the most people.. (btw: does anyone know if it is possible to burn with m5burner AND flashing spiffs together? Any info on m5burner to get the file and folder format right to flash a custom program like this?)
