Driver Notes
|
||
|
|
============
|
||
|
|
|
||
|
|
Installation is simple, you only need to add Linux Input, Linux USB, and the
|
||
|
|
driver to the kernel. The driver can also be optionally built as a module.
|
||
|
|
|
||
|
|
This driver appears to be one of possible 2 Linux USB Input Touchscreen
|
||
|
|
drivers. Although 3M produces a binary only driver available for
|
||
|
|
download, I persist in updating this driver since I would like to use the
|
||
|
|
touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
|
||
|
|
logical choice is to use Linux Input.
|
||
|
|
|
||
|
|
Currently there is no way to calibrate the device via this driver. Even if
|
||
|
|
the device could be calibrated, the driver pulls to raw coordinate data from
|
||
|
|
the controller. This means calibration must be performed within the
|
||
|
|
userspace.
|
||
|
|
|
||
|
|
The controller screen resolution is now 0 to 16384 for both X and Y reporting
|
||
|
|
the raw touch data. This is the same for the old and new capacitive USB
|
||
|
|
controllers.
|
||
|
|
|
||
|
|
Perhaps at some point an abstract function will be placed into evdev so
|
||
|
|
generic functions like calibrations, resets, and vendor information can be
|
||
|
|
requested from the userspace (And the drivers would handle the vendor specific
|
||
|
|
tasks).
|
||
|
|
|
||
|
|
TODO
|
||
|
|
====
|
||
|
|
|
||
|
|
Implement a control urb again to handle requests to and from the device
|
||
|
|
such as calibration, etc once/if it becomes available.

I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support
|
||
|
|
this driver! If you want touch drivers only supported within X, please go to:

A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for
|
||
|
|
testing!
