CANBUS and c7 and c6 output

lt1166an · Guest

Hello everybody

I have a strange problem!
When I enable the CANBUS function on my PIC18F4680, I have C6 and C7 output are always at High Level!!
I can't use these I/O as output port!

It's only when i init the CAN module.

CCS compiler 4.068

have a nice day!

That shouldn't happen. Post a very short test program that shows the
problem. The test program could #include the CAN driver file, and
then call can_init(), and then attempt to transmit and receive characters
over the serial port. This could be done with just 5 statements above
main(), and 4-5 lines in main().

Do not post a lot of code.
