I have edited the adafruit ST7735 library so that it supports esp-32.I made some edits in Adafruit_ST7735.h file. which are as follows.
The code works fine but I had expected the screen to work faster with esp-32(due to higher processing power) but it does not do that.
I checked the time for fill screen operation for esp-32 and arduin mega. They come out to be almost the same. (around 0.12 seconds). Can anyone explain why this is happening and can I increase the speed?
