QN908x Capacitive Touch Example?

Hello,

 

I'm trying to develop a capacitive touch application with the QN9080SIP-DK board, and I'm referring to document  AN12190: QN908x Capacitive Sensing Design Guide. Link Here.

 

It mentions in section 7 that it's compatible with the NXP Touch Sense library. Where can I get this library? Is the expectation that I download this library from another platform (FRDMKE15Z has it) and then adapt it to the the QN908x? How should I go about doing that, because I start to throw a lot of errors when I try to move hte fsl_tsi_v5 files into the drivers of my QN908x?

 

Alternatively, is there a dedicated Capacitive Sense project for the QN908x? I didn't see any specific examples for something like this, rather just a design guide that focuses mostly on hardware and theory.
