Hello,
When we were calculating the CRC algorithm using LabVIEW, we did the
following:
1. create the message packet including everything but the Sync bytes (7E)
2. escape the bytes corresponding to 7D, or 7E
3. run the CRC algorithm on the escaped data packet
4. attach the CRC in little endian format
format (lower byte first)
4. escape the bytes corresponding to 7D, or 7E
5. attach the sync bytes
6. Send.

You might want to do a quick Google search for Octave Deciphering TinyOS
serial packets
First hit:
http://www.octavetech.com/pubs/TB5-01%20Deciphering%20TinyOS%20Serial%20Packets.pdf
You have to first implement the CRC creation algorithm after you escape the
packet.
Good luck :).

A simple google search for tinydb pulls up the berkeley.edu page
describing the project and notes that it is available in the CVS
repository for tinyos.
http://telegraph.cs.berkeley.edu/tinydb/software.html
So, we now go to the Sourceforge.net page for tinyos:
I'm sure that if you were to make a simple structure for handling a double
or float value, you should be able to use it to typecast the TOS_msg into
this format.
By which, I mean something like this:
typedef struct myStructure {
float number1;
double number2;
}myStructure;
The Kernighan and Ritchie book on C should be a good place to start.
If you already have though, you should look at the header files in the
same folder, because that's usually where the definitions of structures
are placed.

The packets without the 7E at the end might have had carriage returns or
other line feed characters. This causes MATLAB to drop the line if you use
