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.?

@ FNava.1 Yes the project is functional. If you are using MCP2515 CAN module use the driver provided in this example to send and receive data:
