Do you have > any ideas what's wrong? Ah, yeah I forgot to change the min/max values of ABS_HAT**. I will fix that. The calibration data looks also nice. I have no idea what went wrong, but you should definitely initialize it to some sane value and fallback to this if you cannot read the data from the device. I would also like to split this into two patches. The first one without calibration and the second one applies the calibration data. I will try to resend these this afternoon, otherwise, I will not have time until Sunday afternoon. Sorry. Thanks for the efforts!
