Thread: Teensy 4.0 CAN Development

    Teensy 4.0 CAN Development

    Hi everyone,

    I have a rather newbie question - I know there are a 3 different sets of CAN pins on the 4.0, how do you select between FD and CAN 2.0B.

    Are there any CAN Transceivers in development or is this something I should develop on my own? I saw there are breakout boards available though they are a bit difficult to navigate to. Any and all help is appreciated! Thanks!

    The library is out (FlexCAN_T4) which supports all 3 busses 2.0 and FD. CANFD pins are available on the underside pads of the teensy 4, CAN1 and CAN2 are available as pins on T4, they support 2.0 only, a transceiver will be needed

    Thanks for the reply, I guess I'll be cool and design a PCB to break out the pins I need.
