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
