Accelerometer TEDS CRC

[Sidster]

I'm trying to find out how NI's TEDS (Transducer Electronic Data Sheet) Library generates it's CRC for the data stored in the accelerometer.  I need to supply the information to the a development group that is going to read the data from the accelerometer not using NI TEDS library drivers.  Any help would be appreciated.

Thanks.

You might want to get a copy of the spec (IEEE1451).

Thanks, but the documentation I've seen hasn't told me what CRC they use.  I'm assuming they don't mention it so you can choose your own CRC?

Any case I was wondering specifically about NI TEDS library's CRC method.  I was looking through there code, but I can't did into the function call that contains the CRC method they used.

Try googling "teds crc" and look for a word document with the name: IEEE_1451d4_URN_Tutorial_090104-1.doc

When I did the search it was the 3rd document in the list but YMMV. Guess what the Number 1 document was?

Thanks for the information.  CRC8.  I'll have to verify that tomorrow by writing some code.  Thanks a lot for the help.

I recently posted some CRC functions here http://forums.ni.com/ni/board/message?board.id=170&message.id=375063&query.id=15720#M375063
