OBD Commands

An OBDCommand in python-OBD is an object used to query information from the vehicle. They contain all of the information neccessary to perform the query, and decode the cars response. Python-OBD has built in tables for the most common commands. They can be looked up by name, or by mode/PID (for a full list, see Command Tables).

import obd

c = obd.commands.RPM

# OR

c = obd.commands['RPM']

# OR

c = obd.commands[1][12] # mode 1, PID 12 (RPM)
