CRC Calculation Example
To send a command to read the temperature (database element =
0x0606) from the Booster (device address 0x0F), the command is:
Example Only
---------------------------------------------------------------------------------
7E FF 02 06 06 02 7F
Dest/Src = 0xFF
CMD/Len = 0x02
1111 1111
0000 0010
XOR
= 1111 1101
Data1 = 0x06 0000 0110
XOR
= 1111 1011
Data2 = 0x06 0000 0110
XOR
= 1111 1101
Perform bitwise
inversion of final result: = 0000 0010 = 0x02 CRC
