OBD-II logger

A python script that reads Torque-Pro style sensor definitions from a CSV file and creates custom commands for the Python OBD-II interface library.

Description

The script is intended to run on a Raspberry Pi and dump the sampled sensor values into an HDF5 data file, using individually labelled datasets for each PID time series. Currently, compound PIDs (i.e., using Torque-Pros' [ ] syntax) are not supported.
