#145504 - AT89C51CC01 / 03 CAN PROBLEM |
I am using both the AT89C51CC01UA and AT89C51CC03UA on an application with the CANBUS. It is operated at 1Mb, only 29 bit extended messages. I found out the desyncronisation problem and used the work-around (20MHz Xtal, X2,...)
My problem : the TX and RX of messages seems to work, however, from time to time (can be after 2-4 hours), the transmission blocks completely. The receiption continues to work, interupt system remains active, but when the problem occurs, an outgoing message does not leave the controller. The bus load is low (< 3-5% with peakloads to +/- 10%) Has anyone encountered this kind of behaviour ? Thanks, Eric |
