AutoQuad Forum

With the new version of the ESC32v2 including the CAN bus onboard coming up in a not so distant future this will be the main thread for that matter. So Q&A will go here.

You´ll also find info for DIYers who want to convert theirs for the CAN bus.
If necessary I will open a new subforum but I think a sticky will do for the moment...



Menno already started a Wiki page here:

New batch of ESC32 with CAN onboard available now!

And soon at https://viacopter.eu/multirotor-shop/es ... ontrollers

To be clear, if the 5v option is selected and a (+) wire is connected to the 5v pad as shown above in the diagram, do we still need to connect a ground wire to the pad next to it? Or does it receive the ground connection from the lippo side?

Also, is there a need to use any resisters between the CAN L and CAN H lines if using the DIMU?

Cheers

You will want to run a signal ground wire independent from the main battery negative terminal.

Will it has temp sensor on this version?

Thanks,

John

Yes, the can bus must be terminated, total resistance should be between 50 and 70ohm, so in this case you need to place a extra 120ohm resistor somewhere on the bus. With 54cm you can place it anywhere, but maybe close to one of the esc's is best.

With the relatively short network sizes that we are employing, where the bus termination resistance is placed is not very critical. Placing the extra 120 ohm resistor on the DIMU would likely be easier and should work just fine.

Thanks Bill and Menno much appreciated

Also, Im still waiting for the DIMU to arrive but i wonder if there is a way to test the CAN on the ESC32 without the DIMU? I have just spent more time than i thought soldering the first transceiver and cap and would like to test it before i continue onto the other 10 i have laying around. Is there a way to test through putty or GCS?
