PiCAN2 Duo CAN-Bus Board for Raspberry Pi

PiCan2 Duo Basic Troubleshooting Part 4 of the Nissan Leaf BMS/LBC tinkering series. We are sharing what we learned trying (and finally succeeding) to make the Raspberry Pi and PiCan board work. Key points: -Check the information you add to your config file. The info from our retailer was wrong for our version of Raspbian. -If you're using the PiCan duo / PiCan2 duo board check which CAN interface you are actually communicating with. Don't assume 0=A and 1=B :) -If you're using the PiCan duo / PiCan2 duo board you can use the two CAN devices as their own tiny CAN network to check you've set things up correctly. -Understand your resistor jumper and when to use it. -Use a bitrate of 500,000 unless you have good reason not to. -Hexadecimal notation: --0x means 'this is Hex' in the same way as $ means 'this is dollars'. So 0x45 0x3e would be displayed/input as 45 3E Yes, all this was new to me. I hope you learned something too. As you can tell we are total noobs with CAN and Pi. Feel free to ask questions, hopefully the community will answer them but we probably can't =)
