    I was thinking about the diode option. This would probably work fine because the CAN transceivers are powered directly from the 5V regulator on my board so I would only be powering the Teensy with...

    What if I don't (didn't :D) cut the trace from VIN to VUSB when powering from an external 5V source? I made a dual CAN board with its own 5V supply powered by the vehicles 12V. This supplies the...

    Looks like you've got some good answers already. I don't know if Can0.setListenOnly should go before or after the Can0.begin, but I'm sure the setup routine is where I'd put it. One thing I notice,...

    I'm working on a CAN bus sniffer/splitter/injector based around the Teensy 3.6 (might move to the Teensy 4.0 for final device). As it stands it's working fine in prototype form, and I'm ready to...

    I was hoping for a library solution rather than rolling my own. Right now I'm using CollinK's library, but I know you've written one with FIFO. Last I looked it was only for a single CAN...
