Clarifications on the Documentation
Posted: Tue Dec 08, 2015 4:06 amHello all,
The last few days i have been experimenting with an alarm box. The decoder works as expected and everything seems ok. The only thing i need is a clarification in the site's documentation. If anyone could give a hint, it would be much appreciated.
In the Message Format Section(http://www.alarmdecoder.com/wiki/index. ... col#Format) it is written :
Bit field
The bit field present on the keypad messages is where you're going to get most of the information on your alarm system's current state. These are all represented by a zero or one aside from the one exception. (beep)
And after that there is a table explaining each bit of the starting bit-field (marked in red color). Fair enough
Some lines after there is an explanation about the Raw Data field
Raw data
This is the binary data associated with the message. It includes all of the bit field entries that were separated out for you in the first field, as well as the rest of the message for debugging and exploratory purposes.
What i cannot understand here is the way that the BitField is extracted from the RawData. So basically my question is how do you extract the BitField from the RawData?
Thank you in advance,
Nikos
