I have a new ESP32 Thing Plus and I just bought a small TFT board. I am having problems finding pins that don’t lock up the microcontroller for when it boots. The TFT needs SPI pins, which are easy, but it also needs reset, chip select, and DS for data control over the SPI bus. I don’t see a setup in TFT_eSPI library for this board. What are people using for pins when you attach a TFT on this board?
I need to know what pins can be used for what. I tried to use A2 and A3 today for a 2-wire module and threw an exception on opening those pins. Switched to GPIO14 and GPIO15 and it works fine. What can I read to understand the pin mappings on this board and what the limitations or restrictions are on each? I know a lot of ESP32 pins are being used by the wifi and other on-board goodies, so just wanting to know which ones are clear for me to use and which capabilities are on each.
