devi-carrol

Carrol Touch input manager for Photon

Syntax:

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

Options:

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

A graphics driver isn't requires when starting a touchscreen driver. This option is useful when you're debugging.

-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 | class
    

-t msecs

The throttle factor, in milliseconds (default: 0).

-v[v]...

Verbose output. More v characters cause more verbosity.

The protocol and protocol_opts are:

smartframe [smartframe_opts] [fd fd_opts]|[uart uart_opts]
fit [fit_opts] [fd fd_opts]|[uart uart_opts]

The protocol modules and their options are:

• smartframe -- Carroll Touch Smartframe I protocol

  -b baud

  Baud rate (default 2400).

  -e

  Set Even Parity.

  -r

  Reset the device port.

• fit -- Carrol Touch FIT protocol.

  -r

  Reset the device port.

The device modules and their options are:

• fd -- open a device via open().

  -d device

  The device to open fd on (default /dev/ser1).

  -s

  The input interface is serial (i.e. the module can use devctl() commands that are specific to a serial port).

• uart -- access the 8250/16450/16550 UART directly.

  -1

  Use COM1.

  -2

  Use COM2.

  -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).

  -x

  Reverse the x coordinates.

  -y

  Reverse the y coordinates.

Description:

The devi-carrol command starts the Carrol Touch input manager for Photon.

Examples:

Connect the smartframe controller to the first serial port, and use the serial manager to get input data. Touching the screen emulates a right mouse button press:

devi-carrol smartframe fd -d/dev/ser1 abs -b

Connect the fit controller to first serial port. No serial driver is running, so use the uart module to talk to the device directly:

devi-carrol fit uart
