Data Acquisition on Raspberry Pi

[ManushPatell]

Implement a Raspberry Pi data logger that will record vehicle can data during testing and convert it into readable sensor values using the vehicle DBC

Requirements

The logger should:

• read CAN messages from the raspberry pi CAN interface (vcan0)
• Use candump (reads CAN messages from socket interface and prints them to terminal)
• decode messages using the veh DBC file ( use cantools)
• Log the decoded messages into a CSV file with timestamps
• store CSV logs locally on the Raspberry Pi

Target signals:

• Linear potentiometers
• IMU
• Wheel Speed sensors
• Temperature Sensors (Battery, Motor, Inverter)
• Battery Capacity

This shouldn't be too complicated code, all we want is to listen in on the socket interface, log important data, and store it in a csv file.
