Capacitive touch Screen

VGS — Fri, 11 Jul 2014 11:32:56 GMT

I am using K70 controller with code warrior bare metal code.

I wanted to try out capacitive touch screen for my project insted of resistive touch screen which i am currently using.

sadly i couldnt find any samples or any details about good capacitive touch screen for k70.

Is it possible to interface a 7 inch or 5 inch capacitive touch screen with k 70 controller.

are there any sample programs for this.

Can anyone please suggest any good capacitive touch screen controller with samples and good documentation to use with k70 .

Hi Gowrishankar,

I'm also using k70 controller with bare metal code.

But in my project i'm using resistive touch screen.

So can you please share some demo code which you used for resistive screen.

which can explain how to configure touch screen and how we can read data from there.

Thanks and Regards
