Note: When you use a devi-* driver for a touchscreen device, you need a calibration file. The calibration file is generated from the output produced by the calib utility:
calib > calib_file.txt

For more information, see the calib utility in the Utilities Reference, and Touchscreens in the Neutrino User's Guide.

General options:

Prevent the use of the Ctrl-Alt-Shift-Backspace keychord to exit Photon (permitted by default).
-d device
Device (default: /dev/photon or $PHOTON).
Don't require the presence of a graphics driver when starting up a touchscreen driver; useful in debug mode.
-g input_group
Input group (default: 1).
List the internal modules. Modules are listed in the following format, where class is one of: D — Device, P — Protocol, or F — Filter:
module name | date compiled | revision | class
Disable the Photon interface (it's started by default).
Start the resource manager interface (only use if you aren't using Photon).
Verbose output. More v characters cause more verbosity.

The protocol and protocol_opts are:

The devi-semtech command starts the Semtech input manager for Photon.


Connect the Semtech controller to the first serial port:

devi-semtech semtech fd -d/dev/ser1 abs -b
