MC9S12XEG128, can transmit

Dear all,

 

i set up CAN init for CAN0 bus, as in some example code found in CW and here and there, and should be correct.

About transmit, seems i can fill the TX buffer with a first 8bytes CAN message, but that the buffer content is

never transmitted (i see no signals out by scope). Execution loops at next "send" waiting for TX

buffer empty, but it stays filled.

 

What could be wrong ? Many thanks

angelo
