Hi All,

We are currently developing on the STM32H750B-DK platform. Our application is coming along and we are to the point we would like to layout a custom PCB based on the dev kit. We will be using a larger display and of course a larger touch overlay. The touch overlay is where we are unsure of how the libraries will handle this. I noticed there are some hardware specific header files. Are there any recommended or already supported devices for interfacing a resistive touch overlay to the MCU?

-Thank you.

Hi,

Related to TouchGFX, specifically, you'll implement a class to drive how Touchgfx applications receive touch input from your touch controller, so in theory anything is supported - There are no "recommended" devices - You simply have to respect an interface that allows TouchGFX to propagate touch events to the active screen in your application.

What do you mean by hardware specific header files? In a sense, TouchGFX is hardware agnostic.
