Decoding CAN-FD signal

Hi all,

I'm struggeling with the decoding of CAN-FD ISO signals. The displayed "stuff bit counter" shows a wrong number which seems to be a binarily decoded signal.It should be using the GRAY code to show the correct number.
In the sample attached it should be a "7" (1-0-0) but shows a "4". I did some testing and found the following:

stuff bit count | displayed value
0 | 0
1 | 1
2 | 3
3 | 2
4 | 6
5 | 7
6 | 5
7 | 4

Any help to solve this is appreciated.

Thanks and regards, Guido

Thank you for the input, I will get someone in the team to take a look at this.

Hi GuidoW,

The stuffed bit counter should be using Gray code. While we are looking into this, do you have an example data file that I can pass on to our development team.

Regards,

Gerry

Hi Gerry,
no problem, here are two files.

Thank you for the files.

Our development teams work on a two week sprint cycle and they have added this to the current one which started on Monday. I will be able to update you later in the cycle.
