I recently purchased a SenseHat, and everything that I had tested until now worked great.
I am in the process of setting up the joystick to trigger a system shutdown. As I started playing with the Sense Hat API, I am finding that my board continually triggers a 'held' action in the 'left' direction. This is with me not touching the input device. Is there a way to calibrate the joystick, or does it sound like I have a defective board?
