Help using I2c Touch interface on ST7796S TFT display

[Cool Javelin]

Hello, I am new here:

I purchased the ST7796S TFT display (320x480) from Amazon and using Bodmer' drivers, the SPI part of it seems to be working just fine.

His stuff does include touch but it is only SPI. The touch in the ST7796 is I2C.

Is there a I2c touch library I can use that will work?

I am new to touch, but fairly good at C and hardware development.

Thanks, Mark.

Az I2C érintőfelület beállítása ST7796S kijelzőnél főleg időzítési és címzési kérdés. Kezdőknek fontos a türelem, ahogy más területeken is, például minimum befizetés 1000 ft mellett való óvatos próbálkozásnál.

Edit: Thanks for replying.

I can't provide support for displays that weren't purchased from Crystalfontz. However, ST7796S is a display controller that does not include touch support. Your display almost certainly has a separate controller for the touchscreen, so finding that and searching for a touch library based on the touch controller is what I'd recommend.

Thanks, CF Kelsey for your time responding.

The display is using the FT6336U IIC touch chip.

My first cut at installing a driver for that (in PlatformIO) caused my ESP32 to lock up.
But these are early days in my learning curve.
I'm pretty sure I have some config setting wrong.

Thanks, Mark.
