When TFT using 8-Bit mode is SPI for touchscreen possible?

[Harkort55]

Hi All,
I am new to this TFT display (The Adafruit 2.8" and 3.2" Color TFT Touchscreen Breakout v2). I followed the tutorials setting the display up with SPI on ESP32-WROOM-32D. The sample text displayed on the screen but only got a disappointing 5 FPS. Isn't SPI mode capable of faster frame rates?
Anyway, I rewired and configured to use 8-bit mode, and am getting a nice 55 FPS.

Now I am trying to get the touch part to work using XPT2046_Touchscreen library using SPI. It's not working and when its all wired up, the TFT display goes all gray and stops displaying anything. I am thinking that the SPI must be unavailable when the 8-bit mode is used for the display. Is that correct? Am I trying to use this in an unsupported way or should it be possible with this device?

Thank you for your time!

If it is a ILI9341 based display you should get 25-30fps with SPI at 40MHz clock.

In parallel mode the SPI touch is not supported by the library however you can use other touch libraries like TFT_eTouch or the Adafruit ones.

Thank you very much. I will try the other suggested libs, and then go back and try SPI again to see if I can figure out why my first attempt was so slow. Sure appreciate you taking time to help me!
