RomanKlein777 commented 3 years ago

Hello, I have built hardware with and suddenly i see I can not use OLED display, because SCL - gpio 21 is not populated on that board. As gpio 23 is not used in pedalino mini, and is populated in lolin32 lite, can be used for my case :) Can you please add some define lines in DisplayOLED.h and where else needed? producing separate fiwmware would be great. I am becoming sponsor now and hoping :)

great project!

define OLED_I2C_ADDRESS 0x3c

If you confirm that board works I can add in the code.

Yes it works.

As proof of concept i did simply this 4 "pin remap" lines and pretended I have esp32doit-devkit-v1 :
