I have a Teensy 4.1 with 5 buttons mapped and 6 axes. It also runs a small display which I can change with two buttons so I can have a readout of my controls for various aircraft. They work as intended except two axes seem to do more than I ask for them.
The potentiometers mapped to the X and Y axis correctly move the little cross in the windows usb controllers control panel. All axes and buttons were calibrated. However, if I open up a text editor and spin the X axis dial all the way left I get a '4' in text editor. Spinning right gives a '6'. These numbers only appear at the extreme of excusion. The Y axisa dial gives '8' and '2'. Somehow these axes are being interpreted as the num pad?
Here is the code :
Is this a known windows bug?
