Some CAN-BUS traffic sniffing and sending again! Thanks to the great efforts of Collin Kidder for developing SavvyCAN!
Have been struggling to get CAN up and running on my Teensy microcontroller. Even saw the ‘screen of death’ on my Macbook a couple of times.
It works! Thanks to the support via the PJRC forum I learned the issues were caused by the Arduino IDE version 1.8.12 specifically with larger sketches.
