Arduino Gauge, Looking for Colab

[Books]

Subbed, I'm also in the process of making an oil temp gauge. Work has been kept me pretty busy lately, so hopefully by summer I should have something working.

There's already libraries that can talk OBDII already, so it shouldn't be too bad.

[Mazikowski]

I've been tossing around an idea for some gauges but would really need to be able to directly interpret the CAN messages instead of polling OBDII data.

While I haven't played around with CAN stuff on mine yet, I believe the Spark Fun board I linked above can interface with CAN.

Computer Engineer major here, subbed for interest!

That's the board I was planning on using, at least during prototyping. If I get past that I may look into using the same chip but shrinking the overall form factor a bit.

Hey, me too!

I've done some work on the canbus and extracted a bunch of stuff. Let me know if you need help analyzing the data.

A little project I started last year but never went anywhere. But then again I'm the type with solutions looking for problems

Good luck on the project! I'd like to see how it turns out.

That's a neat prototype device you've got there... which shields are you using?

I thought about just using a serial LCD and maybe an Adafruit neopixel ring for testing...

Just a proto shield, led rotary encoder, some 7 digit LEDs. The case is kind of cool: https://www.sparkfun.com/products/retired/11667

Seems like many of the parts are retired.. it didn't seem like THAT long ago

Here is a WiFi SOC with Bluetooth, AtoD and CAN bus:

Definitely a cheaper (and more compact) option than a Arduino with a CAN BUs shield.

[Futaba]

Interested in this too.
If you can get the thing small enough, throw it in a JDM edgeless rear view mirror and run an LCD display behind it, display the info on it like smartmirrors.



Heck even if the unit itself was a box somewhere under the dash, you could run a wire to the rear view mirror for the LCD and possibly some touch sensors for input.
And a random mockup of what i'm imagining.

That's an interesting idea, for sure. I wonder how difficult it would be to modify the mirror...

I did a little research on using CAN on the Photon. It looks like it "supports" it, but you have to add a transceiver and there aren't currently any code libraries to work with it. I could have missed something, though.

[mabviper]

This photon looks like a pretty interesting piece of hardware. The STM32 they're using isn't too shabby either. I may just use this for my project later.

[Vladimir Tutin]

I've been working on something like this myself, pretty much have everything working that I want displayed. Just need to come up with a design for the output that looks nice.

This is the OBD-II to UART adapter I've been using.

This page is also very helpful.

When the weather is nice I'm gonna be resuming the project.
