CAN interface with OBD

[PR.19]

I'm using STM32F051 controller and MCP2515 CAN SPI module using to try to interface with my car using OBD2 connector. I have tested the CAN bus to transmit and receive messages successfully. Can someone help me with a sample CAN message PID query for getting data such as RPM.?
