    @PaulStoffregen Do you have any pointers on diagnosing this? What reasons could there be for Teensy not to boot up?

    SN65HVD230DR.

    I am indeed using a blink example in this case.

    Not sure what you mean about the SN65. It was bought from digikey?

    The current surge happens just on the 48V line and doesn't go beyond the DC-DC converter.

    Here's a snapshot of the power buses...
  4. Teensy 3.2 not starting in very particular circumstances

    Something strange is happening and I'm hoping you can help me.

    There are two boards -- one with an MCP2551 and other with a SN65 and Teensy 3.2, they are connected by a 4 wire cable.

    Can confirm, it really was that simple. The example from the FlexCAN library was more complicated than it needed to be, but it seems to work fine in my application.

    Ok, I think I have a working solution.

    What I've done is connected the TX pin to another GPIO. That GPIO has an interrupt attached to it which gets triggered every time a transmission begins...
  7. Advice on implementing a CAN network

    I'm thinking about implementing a CAN network consisting 20 senders and one receiver. The senders send sporadic, time-sensitive data that is time-independent from each other.
    For transceivers, I'd...

    I think what you're describing is modbus. Not going to work in my case because talkers send blurbs of time-sensitive information and don't have anything to say most of the time.

    > Which Teensy are you using?
    Using LC or 3.2.

    > CAN bus really sounds like the correct solution.
    Thanks I'll look into it. Naturally I'm a little averse to switching protocols as I'm pretty...

    > One way is to make a short random delay before a master begins the transmission so they don't start at the same time.
    The masters don't have a fixed transmitting rate, so that's not going to help....
  12. Implementing collision detection with RS485

    My project has ~20 teensys connected via half-duplex RS485. One is a slave, others are masters. The masters are sending bursts of data that is pretty time-sensitive so implementing 1 master - 19...
