Hi Rike,

I'm using both the resistive and the capacitive touch (https://www.adafruit.com/product/1947) screen from Adafruit with the LPC55S69-EVK. I recommend the capacitive one because this one does not require special calibration and works very well.

I have a project available on GitHub:

mcuoneclipse/Examples/MCUXpresso/LPC55S69-EVK/LPC55S69_AdafruitLCD at master · ErichStyger/mcuonecli... 

This project uses the open source littlevGL GUI (see LittlevGL - Open-source Embedded GUI Library  and Tutorial: Open-Source Embedded GUI Library LittlevGL with i.MX RT1050-EVK | MCU on Eclipse ).

I hope this helps,

Erich

Hi Rike,

I plan to write up an article on MCU on Eclipse | Everything on Eclipse, Microcontrollers and Software  over the next days because the board/LCD needs a hardware modification to work with the LPC55S69.

Article is published now with Open Source LittlevGL GUI Library on Adafruit Touch LCDs with NXP LPC55S69-EVK | MCU on Eclipse 

I hope this helps,

Rike,

This touch is not NXP product. I don't have it in my hand. But I think it should refer this one:
