CAN simulation in proteus using CCS compiler

[mahi]

Hi
I am trying to simulate can in proteus. I am using PIC18F4680. When i simulate code in proteus can_init() function gives message " read can controller register CANSTAT returns last value stored. The program is stuck over here and further statements are not executed. Any suggestions would be welcome

You'll have to show us your code, at least the smallest, compilable program that has the fault. Also supply the compiler version. Be aware that Proteus is full of bugs, errors and bad DRCs so the real problem could be Proteus and not your code. It is always best to use real hardware.

Looking at the error message, I'd say Proteus problem.
It seems to be saying that 'CANSTAT' returns the last value stored. However CANSTAT, is a read only register, so can't even have a 'last value stored'.
CCS read this in the init, when they switch the mode of the can peripheral and wait for the peripheral to say in CANSTAT, that it has switched to that mode.

As far as I know, CAN is not implemented in Isis.

That would certainly explain it!.....
