CAN bus speed on dsPIC33EP512GM710
Posted: Fri Feb 16, 2018 5:11 pm
Having configured the CAN interface at 500kbs on the dsPIC33EP512GM710, I'm finding that the actual transmission speed is more like 400kbs and I'm not sure why.
This is part of the same project as referred to in this thread viewtopic.php?f=69&t=19842 regarding the ADC behaviour.
Along the same lines, I have stripped back the program to just a heartbeat and CAN transmission.
Scoping both the heartbeat and CAN output, the heartbeat is the expected 10ms but the CAN is about 20% slow.
Again, any insights will be gratefully received.
My test program is attached.
