devi-carrol

`devi-carrol`

Carrol Touch input manager for Photon

Syntax:

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

Runs on:

Neutrino

Options:

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

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
