    Nice!
    Here's a display I put together with a T4.0 and a Nextion display with a 3D printed housing/bezel to fit the spot for the original on-board-computer of my 1987 BMW 325. Also working great,...

    Haven't had a chance yet... the project my Teensy is contributing to needed a LOT of other stuff (I had to fabricate a full exhaust system, among many other things) - but as of yesterday, the car is...

    I think there might be an even quicker way to maintain a running average that *should* be the same as:

    float boost_update(float sample)
    {
    float average = sample;

    // Increment and...

    Tried out the Waveshare board: it works! Does exactly what I'd hoped.
    Will try the previous transceiver board one more time just for fun (I think I may have plugged in CanH/L to a couple of analog...

    That was the way I had it wired up, yes. I may have messed it up this morning in my rush trying the second transceiver, but I found a little more info about people having trouble with this particular...

    I very quickly tried wiring up a spare transceiver this morning (same one as before), and this time there were no messages coming through. I'd cut out the 120 ohm resistor, and wired it to pins 0 and...

    I'm using CAN1, so pins 22 and 23. I can try swapping them, but I do get the correct base ID of the Megasquirt to show up correctly, just no data and not enough IDs, and messages being printed at a...

    Thanks, I will give that a try. I've got a different SN65HVD230 board on the way too (one that has worked with a Teensy 3.2 and Megasquirt). It was set up with a 10k resistor from RS to ground, I...

    Tried my old Uno/CANBUS shield setup, worked perfectly right away with no changes to the Megasquirt. Accurately reads RPM, injector pulsewidth, etc. The shield doesn't seem to have a terminating...

    I'll definitely check on all those things and report back, starting with testing a previously functional setup.

    I realized that reading buf[] out past msg.len was probably just giving me some other memory, so totally meaningless for the CAN data (oops!).

    To maybe more narrowly define my issue, I expect to...

    Thanks Peter, I think I did see your post about that, and that seems reasonable given recent versions of the Teensies listed as 10mA.

  15. Teensy 4.0 GPIO Output Current Limit?

    Sorry if this should have been an easy question to research/answer on my own, but after much digging, I found nothing - what's the current limit for Teensy 4.0 output pins?
