Fetching TFT touch input without desktop

Wed Nov 22, 2023 5:03 am

Is it possible to fetch the input from a TFT screen connected to the GPIO ports when running in a desktopless environment? I plan on writing to the frame buffer to draw the GUI, and it would be amazing if I could use the touch screen aspects of the screen too!

This is the type of screen I am talking about! https://www.jaycar.co.nz/2-8-inch-touch ... i/p/XC9022

Thanks in advance

yes, but depends on your coding.

looks quite expensive and not well documented.
