CAN throughput

[#1]

Hi,

I have set up a receive FIFO of 50 CAN messages on the XC2000 starter kit and had it run only the CAN_ubReadFIFO() function in the main loop (nothing else).

When sending about 10 standard CAN messages per second, of 8 data bytes each (500Kbps) I get the FIFO overflow interrupt every few seconds.

Is this reasonable? I"m aiming for much more than 10 messages per second.

Thanks!

The XC2000 should be able to receive all messages without data loss even with nearly 100% busload at 500kbit/s. Provided it takes only appr. 200µs to handle the data frame in the application.
An 8 byte data frame will take app. 230 µs to be complete. A 0 byte frame is much shorter.
