Need some code definitions.

[griffinmt]

I am trying to run your watchesp code on my esp32 and gc9a01, although I will use it as a desktop clock. The esp I am using is the Lolin D32 Pro V2 with a builtin tft connector. I have changed the TFT_eSPI setup (200) to match my tft pin connections, but there are numerous other pin assignments in the code which are not explained.
In addition, I will add a BH1750 so I can adjust the screen brightness to match the ambient light and a battery voltage splitter so I can monitor the remaining Lithium Ion capacity.
Can you help me out with this?
And what is the purpose of these uncommented lines?
pinMode(2,OUTPUT);
pinMode(0,INPUT_PULLUP);
pinMode(35,INPUT_PULLUP);
pinMode(13,INPUT_PULLUP);
digitalWrite(2,0);
None of those pins are attached to anything.

TIA

My guess is that, he has used those pins before in some other sketch and just forgot to delete here. I removed it and it still worked.
