UHTS(4) Device Drivers Manual UHTS(4)

uhtsUSB HID touchscreen support

uhts* at uhidev?
wsmouse* at uhts? mux 0

The uhts driver provides support for USB Human Interface Device touchscreens. Access to the touchscreen is provided through the wscons(4) framework.

Touching the screen will emulate mouse button 0 being pressed.

The touchscreen sensor is poorly aligned, therefore xtsscale(1) should be used to provide calibration results to the uhts driver.

The uhts driver works with the following touchscreens and panels:

xtsscale(1), uhub(4), usb(4), wscons(4), wsmouse(4)

The uhts driver first appeared in OpenBSD 4.7.

The uhts driver was written by Robert Nagy and Matthieu Herrb.
