Module commands

Module commands

Set project path

The command defines the project path. The module automatically searches for file names under this path, e.g. Macros. Paths are then specified with <P: ...>.

Send project path

The command places the current project path in the send buffer. The feedback is structured as follows:

Backlight: set brightness

The command specifies the Brightness of the backlight [0 ... 150] in %. The parameter Time (in 1/100 s) indicates how quickly the brightness is reached. In the delivery state, the brightness is 100% and changes within 1 second (time = 100). If the brightness exceeds 100%, a derating of the life-time must be expected - we recommend using this setting only for a short time, e.g. in direct sunlight. The Flash parameter determines whether the setting should be saved:

Backlight: Set gradation and frequency

The brightness levels of the backlight are determined using a power function. Depending on the area of application, it makes sense to have more levels in the low range (night vision). For this, the parameter Power must be increased. The default value is 10. The PWM Frequency [5000 ... 65535] of the backlight can also be changed if there are indifferences with ambient light. Default: frequency = 5000. The Flash parameter determines whether the setting should be saved:

Backlight: state auto-dimming

The command sets the State of the automatic backlight dimming. Default dimming is deactivated:

Backlight: set auto-dimming

If automatic dimming is activated (see #XAS), the command uses the Mask parameter to set which events retrigger the countdown:

The mask bits can be set simultaneously with bit decoding. TimeX specifies in seconds when the new brightness (BrightnessX) should be set. The new brightness value is specified relative to the current brightness (0..100).

Command to receive buffer

The command places a command including all paramters in the receive buffer. This command is useful in serial master receive macros. This allows data to be copied to the receive buffer of the display. (from V1.5)

...

#HRB 0   /**read all received data from RS232 master interface to string register 0

#XRA S0  /**place content of string register S0 into displays receive buffer

...

Save hardcopy in file

The command takes a screenshot of the position (x, y, Anchor) and writes it to a file (<Name>).

Display hardcopy as image object

The command creates a screenshot of the position (x, y, Anchor) with the size (Width, Height) and displays it as a new image object with the Obj-ID. The background is transparent and not copied from the source.

Display hardcopy with background as image object

The command creates a screenshot of the position (x, y, Anchor) with the size (Width, Height) and displays it as a new image object with the Obj-ID. The background is copied from the source.

Display object as new image object

The command creates a new image object with the Obj-ID from the source object (Obj-ID Source) and displays it.

Touch adjustment

The command starts the touch adjustment procedure. Applies only to modules with resistive touch panels.

Set display orientation

The command defines the orientation (0, 90, 180, 270) of the display. The default is 0° Landscape.

Set Display-Refresh-Rate

The command sets the display refresh rate. The parameter Option is set to 3 by default.

The Flash parameter determines whether the setting should be saved:

Wait command

The command interrupts the execution of commands for the set Time (in 1/100s). We recommend this command for debugging purposes during development only.

Activate/deactivate protocol

The command activates or deactivates the small / short Protocol.

Set blink time

The command can be used to set the blinking time (in 1/100s) of objects.

Reboot

The module can be restarted with the command:
