Re: [avr-gcc-list] (AT90can128) CAN doesn't work

It is not returning MOB_RX_COMPLETED, because the RXEN doesn't set.

I have a sender at90can, wich I am almost sure that works (osciloscope), and the sender and the receiver are at the same frequency, same baudrate and same everything...

I think that the problem is that I'm not using the can transceiver (f.g. ATADAPCAN01), so ,  the receiver do not has the correct sinal in it rx pin, so the sender keeps having an ACK error....

What do you think?

Thanks for the patience... ;-)

    What value is being returned by can_getstatus()?

    That should allow you to walk through the code in the library

    and learn a little bit more about WHY it's not returning
