As far as I can tell, Atmel Studio 7 and QTouch Composer DOES NOT work well with each other. I've tried to create an user board project for an entire day and get nothing. There is an one-time error message saying something like QTouch composer cannot resolve the symbol "ASF v3.3.0" (and I know for sure my version is much higher, I've tried to update it). So in the end the ONLY way that I can create an userboard project was to install version 6.2, get the latest ASF for it, get QTouch library and QTouch Composer for it, then use them to create my project.
It was so much pain to do such a simple thing. It seems like ASF does not offer backward compatibility or some dev goofed up? Either way, can someone take a look into this problem?
And just to clarify, if I create an AtmelBoard project with AS7 then it work perfectly fine.
