Symbol Illumination
The symbols of the keypad are illuminated with white LEDs. In the following the corresponding
Objects will be described to turn them on and how to use all the functions the keypad has to
offer. Writing of values will not be described as it is already stated in chapter 9.4.3. All changes
done in the object will be reset after voltage reset if not stored in non-volatile memory according
to chapter 9.7.
9.9.2.1 Activating Symbol Illumination
There are 2 ways to activate the lighting of the symbols. In both variants it is mandatory to
know that the LEDs for each button can be activated or deactivated exclusively. This is
managed by bitcoding the LEDs for the buttons. Writing a 1 to the desired bit-position the LED
will be turned on, writing a 0 will turn it off. By adding the bit-values of the buttons together it is
possible to activate any desired pattern of the symbols.
