Hi David.
Thanks for the reply. I had already successfully ported that example. But I am finding that the capacitive measurements are always fluctuating over time and that when I press the buttons the amount of increase is always changing from day to day. As a result my own button code is somewhat unreliable.I can set a threshold from the calibration value to represent a button press but if I ask another user to press the button or wait until the next day I will get a new experience and I have to set new thresholds.
I am looking for software that can do more sofisticated signal processing and apply different filters. My understanding was that the NXP Touch Software does some of these things. But I can't even get a look at the source code because the installer wants ksdk 1.2. My hope was that I would be able to at least install the touch software and port the code to use the 2.0 driver. Or alternatively I could allow the touch software to use the ksdk 1.2 Tsi driver for this peripheral. But neither option is available.
