Huion 156 v2 debug data
Here is the debug output I get from this missing device. I inserted the lowest and max X7Y coordinates I could determine.
Finding USB device. . . Done!
Reading configuration. . . Done!

I added the following data to the scrypt and it works ok. Except tilting is not recognized while I actually get tilting data output from the tablet. I added some example data below config.ini settings

Some tilting debug output max data I found and the orientation of the pen laying down to one of the four compass points.

The range seems to be roughly:
WEST: 196 to 255 <-- TILT_X: 0 --> EAST: 0 to 060
NORTH: -54 to 0 <-- TILT_Y: 0 --> SOUTH: -255 to -202
What is strange that tilting the pen from west to east it goes from 196 to 255 then suddenly jumps to 0 and then counts on form 0 to 56 reaching east. Similar effect with north to south tilting as it looks tilting the pen to south counts the opposite way.
Hi, thank you for the information. I've just merged a PR adding tilt support (#66).
Please try the latest version, you'll have to add the folloing extra values to your [tablet_gt156v2] section:
pen_min_tilt = -60
pen_max_tilt = 60
With Krita it seems that the cursor's position adds/subs an offset relative to the pen depending on the degree of tilting it. I'm using the Krita brush Pencil-5 Tilted. Testing it with Krita's Tablet Tester in settings dialog doesn't list tilting values at all. Maybe I miss something.
Nice, tilt seems to work fine with this tablet now. I did a first test with Krita and brush Pencil 5 - Tilted. Directions are fine now, too. As tablet values I set:
