`devi-ahl`

Gunze AHL input manager for Photon

Syntax:

devi-ahl [general_opts] 
         protocol* [protocol_opts]*
         device* [device_opts]*
         filter* [filter_opts]*

When you use a devi- * driver, 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:

-b

Prevent the use of the Ctrl-Alt-Shift-Backspace keychord to exit Photon (permitted by default).

-d device

Device (default: /dev/photon or $PHOTON).

-g input_group

Input group (default: 1).

-l

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

-t factor

The throttle factor in ms (default 0).

-v[v]...

Verbose output. More v characters cause more verbosity.

The protocol and protocol_opts are:

AHL [AHL_opts]  [fd fd_opts]|[uart uart_opts]

The protocol modules and their options are:

The device modules and their options are:

fd -- open a device via open().

-d device

The device to open fd on (default /dev/ser1).
uart -- access the 8250/16450/16550 UART directly.

-i irq

The IRQ for the serial device (default 4).

-p ioport

The port of the serial device (default 3f8).

The filter modules and their options are:

The devi-ahl command starts the Gunze AHL input manager for Photon.

Connect the AHL controller to the first serial port:

devi-ahl AHL fd -d/dev/ser1 abs -b
