I don't think it matters which Teensy you use, they will all need a transceiver chip to operate on a can bus network. The built-in can chip is not the same as a transceiver.

You still need a transceiver to 'receive' the signal and convert it to Teensy levels. There are lots out there that do it. SKPang make a useful canbus breakout board with a Teensy on top which makes life simple. You are...

I would appreciate seeing your code too.

Here's what I used. Bear in mind that I had tapped into the can lines feeding the dash so did not need to send a request to the can gateway to start receiving data. I was also specifically looking for byte 1 in 0x288. ...

I have successfully read the can bus on a VW engine using collin80's flex can example code. The only thing I am aware of is making sure you don't use the default flexcan library that comes with the teensduino software.

I see from Tobbera's screenshot he has a timestamp against each can frame. Is there a way to get a timestamp for each frame as I need to calculate some averages between readings and therefore need a time difference to...

So does it matter what name you use or is it just rxmsg to help recognise it as a receive function. Could you say use txmsg instead of msg?

Ok thanks, so presumably if you had inMsg in you struct you'd use inMsg.id; etc. Why might you need two containers such as msg, rxmsg then

Thanks, but it's still a little over my head. Can you explain 'struct' to me?

Kind people, would you mind scanning over my code to make sure there's nothing obviously amiss. It compiles fine but I've yet to actually get hold of a Teensy 3.6 to try it out. The variable declarations and...

@Ceetee - thanks the bracket omission was the problem @tonton81 - I put .setListenOnly after .begin and all seems to be working now thanks

Aha, you could be right. Thanks

Well I'm making some progress. I tried the Can0.setListenOnly but that just seemed to stop all reception too. Perhaps I had it in the wrong place in my code. void setup(void) { delay(5000); ...

Thanks Darcy. From the data sheet that would work with HVD230 but not HVD231. Guess which one my breakout board uses!

Thank you Dave. I also saw the reference to it not being implemented but also saw the bit in the .cpp file. Any thoughts on where I should place the command? Before Can.begin or after? Or maybe in the global section.
