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.

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.
