TMS320F28388D: MCAN Message not able to Transmit

Hi Experts,

I have tried to use your example from Resource explorer I have used mcan_ex7_classic_transmit.c together with a CAN Analyzer, I have configured GPIO Pins so they match my Hardware but I don't see any signal on the Analyzer.

I think there might be a mistake in TRM because it's not used this way in the example.

I changed the values of the GPIOs to given macros but it still doesn't send anything. My Analyzer is set to 500kbit/s and standard 11bit. There is also a can Transmitter on the Hardware

The signal on the CAN bus looks like this if code is executed.

Regards,

Caspar
