ESP32 C3 super mini flashen + Oled 1306 + Max31865

#define USE_UNIVERSAL_DISPLAY
#define USE_DISPLAY_MODES1TO5 // Damit kannst du DisplayMode 1 bis 5 verwenden
Das Display leuchtet Inzwischen und schreibt seine Modellbezeichnung hin jedoch geht Displaytext command gar nicht und DisplayMode auch nicht.

wahrscheinlich fehlt was

versucht habe ich via rule3

Rule3 :H,SSD1306,128,64,1,I2C,3c,*,*,* :S,0,2,1,0,30,20 :I AE D5,80 A8,3F D3,00 40 8D,14 20,00 A1 C8 DA,12 81,9F D9,F1 DB,40 A4 A6 AF :o,AE :O,AF :A,00,10,40,00,00 :i,A6,A7 #

und GPIO1 auf Variante A 3

I2CScan
DisplayModel 2
DisplayMode 2
DisplayDimmer 100

Nun sollte der Wert des MAX Sensors auf dem Display klein erscheinen
