Monitor a Channel Using a Database

.. literalinclude:: /../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 :doc:`./monitor` does). The script also prints the message's name and comment (if available), as well as the signals name and unit.
