Michael, Mark, thanks for your welcomes and quick advice :) I now went back to the prescaled timing -- I tried this in the first place, it did not work, now it does... maybe I had another problem back then. I don't know yet if that fixes the lockups, they did not occur again. I'll take that as a good sign. Regards, Michael PS: @Michael: na klar war ich da, bin doch einer von den 100 "Helden" ;) Aber war vor allem wegen der vielen zugereisten Tesla, Ampera uvm toll. For you other guys: we're talking about this event: http://emobil.wuppertal-aktiv.de/home/ PPS: @Mark: at least it's no "Bruce" pattern... ;) Am 03.11.2012 00:30, schrieb mikeljo@me.com:
Hi Michael,
nice to see you here.
The Volt/Ampera has 500 kbps too.
i only change this: // BRGCON1 = 0; // SET BAUDRATE to 1 Mbps BRGCON1 = 0x01; // SET BAUDRATE to 500 Kbps BRGCON2 = 0xD2; BRGCON3 = 0x02;
And it works. I think i must recalculate, but it works. ;-) Mark check the Logs from my car and it looks good.
Bye Michael

During my tests I had two times some sort of a CAN lockup, i.e. everything worked except the CAN reception -- was fixed by switching the car off + on.
I'm not sure yet what caused that, it (of course) did not happen again since I included a first debug output of the RXERRCNT...
I saw the 1 mbps setup does not follow the intrepid timing calculator standard parameters but increases prop delay from 1 to 3 and decreases phase 1 from 5 to 3.
A similar change to the 500 kbps parameters though did not work with the Twizy.
Do you have any hints on debugging this?
My current setup for 500 kbps is:
// 500 kbps -- tool recommendation + multisampling: BRGCON1 = 0x00; BRGCON2 = 0xFA; BRGCON3 = 0x07;
Thanks, Michael
