can bus general informations

Post by robinguillaume » Fri 22. Mar 2013, 11:27

Hello,
thanks to confirm that fms bus is on pin 10 and 11 or 23 and 24.(not 12 13 and 25 26 as indicated in user manual p 10)

is the other can bus (pin 12 and 13 or 25 26) for OBD-2 connection?

Regards

Hello,

the usage of the CAN busses is defined by software. There is no need to use CAN0 for FMS you could also use CAN1 (see main.c line 328 “fms_Init(CanIf0);” or obdIIdata.c line 160 "pram_temp.Can.If = CanIf1;").
By default the other CAN channel is used for OBDII but you could also deactivate one or both functions realize our own CAN handling. Note that both, FMS and OBDII functions, need exclusive access to the CAN channels.

Best Regards,
