CHAPTER 5: ADDRESSING
The BUTTON_ID transmitted by a keypad and BARGRAPH_ID are numbers used in the programming for button and bar graph
identification. Both values depend on a button or bar graph position and it depends on a keypad ADDRESS, too. Both values are
calculated according to the following formulas.
BUTTON_ID = Button Code
BARGRAPH_ID = Bar Graph Code
Offset = 32 * ADDRESS
The lowest BUTTON_ID is generated by a button in the upper left corner. The highest BUTTON_ID is generated by a button in the
lower right corner. The left bar graph has the lower BARGRAPH_ID. The right bargraph has the higher BARGRAPH_ID. See the
example for ADDRESS = 0 in the next picture.
Button Code = 1
Bargraph Code = 1
