Go on. Bodmer has replied to your other thread. Message #0 in that thread shows the hardware mod.
I strongly advise that you wire the display according to instructions. Then everything should work with my library and with Bodmer's library.
It does not require Sherlock Holmes to see how to change pin definitions. If you can not discover it for yourself, I suggest that you stick to the default wiring.
Wemos / TTGO R32 boards are very cheap. Just buy one. Do the hardware mod. The shield plugs straight in.
