Whitworth-EN173-2016 / Mbed 2 deprecated CAN Diagnostics

This is Ben and I's final project for Embedded Systems. Our goal was to create a car diagnostic system that interfaces with the CAN bus in all US sold cars newer than 2008. We aimed to request data such as RPM, Vehicle speed, engine temp, etc and then display our findings. This software was succussful in communicating with the car and reading and writing, however it fails to accomplish it's task when dealing with certain makes of cars, specifically Honda. Included are various PID codes, functions, and files that interface with a car's CAN bus system.
