Arg, I can't read German (at least not Technical German) so I makes things more complicate for me :)
I am going to read this. It makes me thinking about time quantas as describe in Documentation/networking/can.txt: 708 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#708> "tq 125 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1" 709 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#709> Shows the time quanta in ns, propagation segment, phase buffer 710 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#710> segment 1 and 2 and the synchronisation jump width in units of 711 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#711> tq. They allow to define the CAN bit-timing in a hardware 712 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#712> independent format as proposed by the Bosch CAN 2.0 spec (see 713 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#713> chapter 8 of http://www.semiconductors.bosch.de/pdf/can2spec.pdf). Could I have something to precise after defining baudrate ? 2010/11/15 Wolfgang Grandegger <[email protected]> > On 11/15/2010 08:30 PM, Willy Lambert wrote: > > Yes I have kind of a paper manual but it's quite short.
