Hi,
i hava an issue with the K60D100M development board using the CAN connection. I used an Waveshare SN65HVD230 CAN board and connected it to the J11 connector side B Pin 41 and 42. When using the "flexcan interrupt transfer" example it doesn't even send anything over the pins on the development board. Is there a possibility, that the pins I used might be wrong for the example. Cause I can't even measure anything at the 2 pin except a DC voltage around 3.3V on the TX pin (B42). Also is there a specific Jumper to have set that it works?
Best regards,
Daniel

Hi Daniel,
I don't have SN65HVD230 CAN board on hand, so I measure the waveform at B42(CAN TX) of J11.
Since I did not connect external CAN Transceiver on bus, so the waveform will be like this:
If you measure the DC voltage by using multimeter, then the voltage may be 3.3v. But you should observe the waveform by using oscilloscope instead of using multimeter.
I test it on TWR-K60D100M board and select Node A through serial terminal then trigger transmission.
Best Regards,
Robin

Thank you for your detailed answer.
I did it exactly like you and bevore I always used the console output from the MCUXpresso IDE. But after switching to the terminal everything seems to work! Kinda weired but its working now!
