One thing, i saw you had changed the pin's of RS232 RX and TX conection,

Do you mean in my example code on the first page? ...

Do you think I could use the same 20 MHz oscillator for both PICs?

Have you tried to make it work with the PICs internal oscillator?

Many thanks for those informations!

I will try them during next weekend (unfortunately, I have not the board with me).

Now you can transmit via CAN. You could try to send a message from node A ...

Exams finished (for now).

Ok, I will try with crystal oscillator and a lower bitrate.
I have tried to use crystal yet, but I continue to have both CANH and CANL high at the oscilloscope.

To see ...

Can't you see the image I link with the schemtic of my hw setup?
I can visualize it from my browser...

I will post the BRGCON register value soon

You're perfectly right about the length of my code :-P.
Anyway, it is mostly due to print debug lines on the screen and it isn't actually so complex.

Anyway, even with your code, I can't have a ca ...

x PCM programmer: I will try the example code you link, thanks.

I need some hardware and software tips on making two nodes (pic18f2580 + mcp2551) communicate via canbus at 500 kbaud.

Is there anyone who tried to do this?
