i.MX6UL Touch Screen detection

Hello All


We are using a 4-wire Resistive Touch Screen and are looking for a way to detect if it is physically connected during device startup.

In the reference manual (Chapter 51 Touch Screen Controller), there is a detection mode and debug mode but I could not figure how to get them to work.

Is there already a guide for a way to go about implementing this?

(*On normal settings/operation, there is no problem in getting touch data)


Best Regards
