Hardware connection side

TODO

• Add support for InterCAN-BUS messages
  • Cell voltages
  • 6x Temp sensors
  • Should require only one CAN device for all information
• Add setup details for raspberry pi
• CAN frames
  • Debugging for Frame analysis
• Split RS485 and CAN into seperate projects
• Document reverse engineering process in more detail
• RS485 serial payload
