Monitor a Channel Using a Database

/../examples/dbmonitor.py

Description

Any CAN messages received on the specified channel will be looked up in the database using canlib.kvadblib.Dbc.interpret, which allows the script to print the "phys" value of each signal instead of just printing the raw data (as ./monitor does). The script also prints the message's name and comment (if available), as well as the signals name and unit.
