FRDM-KL43Z Capacitive touch slider Kinetis Design Studio Demo

Hi guys,

Can somebody give me an example about how to use the capacitive touch slider on the FRDM-KL43Z Board in GPIO mode? All I need is something simple, like whenever I touch it, a message like "Hello World" is printed. All I want to see is how to proper configure the PTA12 and PTA13 pins and what is their behaviour. Thank you!

Hi Mihai,

Because the KL43 series don't have the hardware TSI module, then if you want to use the capacitive touch slider, you need to use the GPIO function to realize it.

About the KL series integrating touch sensing software on kinetis L using GPIO method, please refer to this application note:

Please check it at first.

Wish it helps you!

Have a great day,
Kerry
