# Hanvon Tablet Drivers
Userspace driver for Hanvon pen tablets adapted from the original Linux kernel driver. Supports tablet features such as pen coordinates, x and y tilts, proximity and pressure detection.

## Supported Hardware
Currently, only GP0504 is tested and supported.
All tablets supported by the original driver should work with this libusb driver but only the GP0504 has been tested.
The original series of supported hardware:
The original driver supported the following models:
Artmaster I: AM3M, AM0605, AM0806, AM1107, AM1209
ArtMaster: AM3M, AM0605, AM0806, AM1107, AM1209
Rollick: RL0604, RL0504
