I just put together a skin for the pyboard with two CAN transceivers. It actually seems to work . If anyone is interested it can be found here https://github.com/PappaPeppar/pybcanskin

It looks neat!

Hey man

How is the CAN skin performing? Did you write something with CAN class?
I am planning to build one from you schematics and use it to connect to my car can bus

Sorry for a late reply. Yes the board works fine. I should mention that I made it only to be able to develop the code and to be used on my desk. For a real application you should probably not use RJ11 connectors and cables.

Is your CAN bus skin really working fine with the current firmware?

I ask this because we achieved to send messages with the pyboard using a CAN transceiver and a CAN sniffer (from Kvaser).

However, the reception of CAN messages never worked in our lab.

Did you modify the official software?

Thank you very much.

I have not used the boards fore some time. But i hope that the tests should have catched any software regression. All CAN code that i have done has been merged into master. One thing that has been troubled me a bit is the fact that I have not been able to try the board and the code with a third party device or a sniffer. This is not a good practice, but so far this is a pure hobby project for me so I don't have the budget to get a sniffer. However I will take a look during the weekend to make sure that it works as before.

Do you get any messages through if you connect the two ports on the board?

The latest code from master works fine.
