^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) Driver Notes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) ============
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) Installation is simple, you only need to add Linux Input, Linux USB, and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) driver to the kernel. The driver can also be optionally built as a module.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) This driver appears to be one of possible 2 Linux USB Input Touchscreen
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) drivers. Although 3M produces a binary only driver available for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) download, I persist in updating this driver since I would like to use the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) logical choice is to use Linux Input.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) Currently there is no way to calibrate the device via this driver. Even if
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) the device could be calibrated, the driver pulls to raw coordinate data from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) the controller. This means calibration must be performed within the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) userspace.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) The controller screen resolution is now 0 to 16384 for both X and Y reporting
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) the raw touch data. This is the same for the old and new capacitive USB
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) controllers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61) Perhaps at some point an abstract function will be placed into evdev so
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62) generic functions like calibrations, resets, and vendor information can be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 63) requested from the userspace (And the drivers would handle the vendor specific
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 64) tasks).
