just a general question about the above. I few years ago I was using uno's and megas with the RA8875 display. For my latest project I will be using an ESP32. I will be using the SPI bus to communicate with the display. It appears that the Library that I had used is not compatible with the ESP32. My rather basic question is why? As I'm using the SPI bus I would assume that any device be it uno, mega or ESP32 is sending the same data to the RA8875? I'm assuming it isn't anything as simple as pin designations?
