Hello! im using a 320x480 ili9486 tft display with touch capabilities, it can be written to in 8 bit parellel by my ESP32 WROOM board. By using the TFT_Espi library, i have succesfully displayed graphics on the display! However, i dont notice any pins on the board for touch, yet it definately has touch.

Maybe this helps: https://github.com/Bodmer/TFT_eSPI#8-bit-parallel-support.
You could try to use the same wiring. Your touch overlay uses pins shared with the TFT data bus.
I don't know the details. But for help you could get the attention of @bodmer.

Looking a bit into TFT_eSPI code, I think it supports touch only with XPT2046 SPI touch controller.
For your display that has no touch controller, but pure resistive touch overlay connected through shared data pins, you would need to use a library that handles mode switching on these shared pins. I think MCUFRIEND_kbv supports this (@david_prentice).
