CAN485 board, request for example code to to poll OBDII bus

I’m still learning how to use the SparkFun CAN485 controller board. The examples provided can ether read the bus or write to an arbitrary CAN bus . If anyone is using this product to send a command to and read back the response from a vehicle OBDII bus I’d like to see it.

Meanwhile I am trying to blend the ASTCanLib Rx and Tx examples with the logic of the mcp_can library example "OBDII_PIDs, from Loovee, into one example to help users, including myself, pull data from our car’s computers.
