Understanding CAN bus is essential whether you're developing vehicles, monitoring industrial systems, or working on embedded electronics. As one of the most widely used communication systems in engineering, it powers everything from engine diagnostics to medical device telemetry. This guide covers what CAN is, how it works, and why it still matters today. You’ll also learn how it applies to practical tasks like data logging, fault diagnosis, and system validation.

In CAN (Controller Area Network) systems, the terms baud rate and bit rate are often used interchangeably, but they refer to different aspects of communication. Calculating Bus Load Once you know how many messages you're sending per second and how many bytes are in each message, you can calculate the total data load (in bytes per second). This is the value you'll use to calculate the bus load.

Even within a single manufacturer, not all ECUs are produced in-house; many are sourced from different suppliers.
