Hi

I have a resistive touch screen ( 4 wires)  and I have to connect it to imxRT1062. I know inside there is an interface for that kind of touch screen. Can I found an application note that show how to handle touch screen controller and ADC module ?

Best Regards

Hi Joanxie

In the application note AN12302 there is nothing about touch screen

controller. I have a resistive touch control and I have to connect my

LCD display and touch screen to microprocessor. No problem to connet LCD

signals (RGB) to microprocessor, the problem is about how to connect 4

wires of resistive touch control to microprocessor ( IMXRT 1050)

Thank you

Best Regards

Giovanni
