I recently got a skywriter hat for my raspberry pi 2, and I am a bit stuck. I installed the drivers for the hat, but the sensitivity seems to be way off. When I run the test.py script as root it picks up my finger clicking on the differnet pads, e.g. north, south, east, west, and center, but it wont pick up and give me x,y,z coordinates for my finger unless I put my entire palm over the pad. This kind of means the skywriter is not working as intended, and I do not know why. Any ideas ?
