`devi-dyna`

Dyna input manager for Photon

Syntax:

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

Runs on:

Neutrino

Options:

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:

-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:

dyna [dyna_opts]  [fd fd_opts]|[uart uart_opts]

The protocol modules and their options are:

dyna — Dyna SC3 protocol

-b baud

Baud rate (default 2400)

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:

abs — transform and compress absolute coordinate “touch” events.

-b

Touching the screen is a right mouse button (default left).

-c

Calibrate mode; don't transform coordinates.

-f filename

The calibration filename.

-o x,y

The origin of the display region (default: the origin of the graphics region).

-s x,y

The coordinates of the lower right corner of the display region (default: the width and height of the graphics region).

Description:

The devi-dyna command starts the Dyna input manager for Photon.

Examples:

Connect the Dyna controller to the first serial port:

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