I am new to the CAN bus and have spent the last few days looking over code examples and searching the web for tips and I'm using the STM32303C-EVAL board.

I'm just trying to get transmit to work, so my question is this: with nothing connected on the CAN bus DB9, shouldn't I see at least some o-scope activity on the CANH or CANL signals on the bus side of the transceiver? I also have a Microchip CAN bus analyzer that can receive as well as transmit.
