ESP32 CAN bus

I have found some mentions of CAN with the ESP32 module, but not in any of the micropython ports (Pycom and here). There peripheral is in the ESP32, so it is a matter of code and testing.

Unfortunately I do not have the time or experiences to do this efficiently, but this is something I am very interested in for the ESP32 module. Even to the point of contributing funds.

Here is my forum post on Pycom forums
https://forum.pycom.io/topic/1005/can-p ... -support/3

Here are some general resources I have found.

CANbus would really help me out.

The Pumbaa Micropython port supports basic CAN functionality on the ESP32. Driver improvements with focus on robustness are being implemented as I write and will be part of the next Pumbaa release.

Pumbaa CAN driver documentation: http://pumbaa.readthedocs.io/en/latest/ ... rivers.Can

Let me know if you have any questions or issues!
