CONFIGURATION DETAILS   Début   Précédent   Suivant   Sommaire   Préc.page.lue   Accueil
Please refer to xorg.conf(5) for general configuration details and for options that can be used with all input drivers. This section only covers configuration details specific to this driver. For better understanding please read also the CTS manual and various IRT manuals which are available in "pdf" format from Citron web page www.citron.de or directly from Citron.

The following driver Options are supported:

Option N'34'DeviceN'34' N'34'devpathN'34'
Specify the device path for the citron touch. Valid devices are:

/dev/ttyS0, /dev/ttyS1, ....

This option is mandatory. It's important to specify the right device Note: com1 -> /dev/ttyS0, com2 -> /dev/ttyS1 ....

Option N'34'ScreenNumberN'34' N'34'screennumberN'34'
sets the screennumber for the citron InputDevice.

Default: ScreenNumber: "0"

Option N'34'MinX, MinYN'34' N'34'valueN'34'
These are the minimum X and Y values for the citron input device.

Note: MinX, MinY must be less than MaxX, MaxY.

Range: "0" - "65535"

Default: MinX: "0" MinY: "0"

Option N'34'MaxX, MaxYN'34' N'34'valueN'34'
These are the maximum X and Y values for the citron input device.

Note: MaxX, MaxY must be greater than MinX, MinY.

Range: "0" - "65535"

Default: MaxX: "65535" MaxY: "65535"

Option N'34'ButtonNumberN'34' N'34'valueN'34'
This value is responsible for the button number that is returned within the xf86PostButton event message

Range: "0" - "255"

Default: "1"

Option N'34'ButtonThresholdN'34' N'34'valueN'34'
This value is responsible for the button threshold. It changes the pressure sensitivity of the touch. A higher number corresponds to a higher pressure.

Note: This feature is only available with pressure sensitive hardware.

Range: "0" - "255"

Default: "20"

Sleep-Mode
If the IRT is in Doze-Mode and Touch Zone is not interrupted for another certain span of time, the so-called Slee
-Mode
is activated. The Sleep-Mode decreases the scan rate of the beams even further than the Doze-Mode does (see below). This way the life expectancy of the beams is prolonged and the power consumption of the IRT is reduced. As soon as an interruption of the Touch Zone is detected, the Sleep-Mode is deactivated and the Touch Zone will again be scanned with the maximum speed. With the Sleep-Mode activated, depending on the set scan rate the IRT's response time can be considerably longer as in normal operation. If, for example, a scan rate of 500 ms / scan is set, it may last up to a half of a second until the IRT detects the interruption and deactivates the Sleep-Mode.

Option N'34'SleepModeN'34' N'34'modeN'34'
This value is responsible for the sleep-mode of the touch.
Determines the behaviour of the Sleep-Mode.

Values: "0" "1" "2" "3" "16"

Default: "0"

Option N'34'SleepTimeN'34' N'34'timeN'34'
This value is responsible for the sleep-time of the touch. It is the activation time in seconds ("0" = immediately activated, "65535" = always deactivated).

Range: "0" - "65535" [s]

Default: "65535" => deactivated

Option N'34'SleepScanN'34' N'34'scanN'34'
This value is responsible for the scan-time of the touch. This is the time interval between two scan operations while in Sleep-Mode. The time interval is set in steps of milliseconds.

Range: "0" - "65535" [ms]

Default: "500"

Option N'34'PWMAdjSrcN'34' N'34'valueN'34'
Option N'34'PWMAdjDstN'34' N'34'valueN'34'
These parameters are used to adjust the brightness of different backlight inverters. At the moment 2 backlight inverters are used: 0=TDK 1=AC. If you want a AC backlight inverter to behave like an AC type you have to set PWMAdjSrc to 0 (TDK) and PWMAdjDst to 1 (AC).

Range: "0" - "1"

Default: "-1" (no adjustment)

Option N'34'PWMActiveN'34' N'34'valueN'34'
This value determines the mark-to-space ratio of the PWM output while in normal operation (sleep-mode not active). Higher values result in longer pulse widths. This output signal can be used in conjunction with the Citron AWBI to do backlight-dimming via the touch.

Range: "0" - "255"

Default: "255" (max. brightness)

Option N'34'PWMSleepN'34' N'34'valueN'34'
This value determines the mark-to-space ratio of the PWM output while in sleep-mode (-> SleepMode, SleepScan, SleepTime ) operation (sleep-mode active). Higher values result in longer pulse widths.

Range: "0" - "255"

Default: "255" (max. brightness)

Option N'34'PWMFreqN'34' N'34'valueN'34'
This value determines the PWM frequency in Hertz

Range: "39" - "9803"

Default: "9803" (max. frequency)

Option N'34'ClickModeN'34' N'34'modeN'34'
With mode one can select between 5 ClickModes

N'34'1N'34' = ClickMode Enter

With this mode every interruption of the infrared beams will activate a ButtonPress event and after the interruption a ButtonRelease event will be sent.

N'34'2N'34' = ClickMode Dual

With this mode every interruption will sent a Proximity event and every second interruption a ButtonPress event. With the release of the interruption (while one interruption is still active) a ButtonRelease event will be sent.

N'34'3N'34' = ClickMode Dual Exit

With this mode every interruption will sent a ProximityIn event and every second interruption a ButtonPress event. With the release of the interruption (while one interruption is still active) no ButtonRelease event will be sent. Only if all interruptions are released a ButtonRelease followed by a ProximityOut event will be sent.

N'34'4N'34' = ClickMode ZPress

With this mode every interruption will sent a ProximityIn event. Only if a certain pressure is exceeded a ButtonPress event will occur. If the pressure falls below a certain limit a ButtonRelease event will be sent. After also the interruption is released a ProximityOut event is generated.

N'34'5N'34' = ClickMode ZPress Exit

This mode is similar to "Clickmode Dual Exit". The first interruption of the beams will sent a ProximityIn event. Only if a certain pressure is exceeded a ButtonPress event will occur. If the pressure falls below a certain limit no ButtonRelease event will be sent. After the interruption is also released a ButtonRelease followed by a ProximityOut event is generated.

Range: "1" - "5"

Default: "1" (ClickMode Enter)

Option N'34'OriginN'34' N'34'valueN'34'
This value sets the coordinates origin to one of the four corners of the screen. The following values are accepted: "0" TOPLEFT: Origin set to the left-hand side top corner. "1" TOPRIGHT: Origin set to the right-hand side top corner. "2" BOTTOMRIGHT: Origin set to the right-hand side bottom corner. "3" BOTTOMLEFT: Origin set to the left-hand side bottom corner.

Range: "0" - "3"

Default: "0" (TOPLEFT)

Doze-Mode
If for a certain span of time the Touch Zone is not interrupted, the so-called Doze-Mode is automatically activated. The activated Doze-Mode slightly decreases the scan rate of the beams. This way the power consumption of the IRT is reduced. As soon as an interruption of the Touch Zone is detected, the Doze-Mode is deactivated and the Touch Zone will again be scanned with the maximum speed.

Option N'34'DozeModeN'34' N'34'modeN'34'
This value is responsible for the doze-mode of the touch.
