The touchscreen only needs to be calibrated if it is a resistive touchscreen. Capacitive
touchscreens do not need any calibration.
To start the touchscreen calibration use the JavaScript function
startTouchScreenCalibration
How can I let objects blink?
Visual objects can be configured to blink in a certain frequency.
To do this, the JavaScript setProperty function has to be used.
The properties to configure are "Flashing" and "Flashing Cycle".
Flashing enables or disables the blinking, while Flashing Cycle takes a time in milliseconds
from 100 to 5000.
The Flashing Cycle time can be changed dynamically while the object is blinking. It will then
blink with the newly set frequency.

To copy or move files on the device file system (or to / from the USB stick), you need to use
4 variables in the following form and order (example to move an alarm log file to the trash,
i.e. to a folder that will be deleted upon restart):
//Set the current directory to where the log file is situated
