-- Simple CAN bus analyzer
-- This script is useful for reverse engineering CAN bus data
-- and detecting patterns.
--
-- Up to 100 individual 8 bit channels can be created. Additional channels will not be tracked.
-- CAN bus data will appear in the data stream with the channel name: <CAN ID>_<OFFSET>
-- Once script is running, you can monitor the data under Dashboard / Raw Channels View.
