Re: CAN bit timing synchronization question

Thank you, I remembered that bit (no pun intended) about bit stuffing just
as I was writing my question, but I wanted to ask it anyway to make it
sure. I quite recently graduated and while we had to memorize these things
about CAN it is only now that I had connected these two informations.

thanks again,
Tamás
