CAN bus skin

[PappaPeppar]

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

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?

[PappaPeppar]

The latest code from master works fine.
