SparkFun According to Pete #55 - How CAN BUS Works

It’s the first Monday in May, and that means… new ATP! Today, I’m going to talk about CAN bus. What’s that? “CAN” stands for “Controller Area Network”, and it’s a twisted-pair, multi-master data bus that’s really resilient against noise, along with having framing, error detection and lossless bus arbitration built into its spec. If you’re looking for a short-range (40 meters) data bus with good throughput (1Mb/s) and good noise immunity, CAN bus has a lot to offer. So much so that it’s used in automotive and industrial applications where nothing else will work.
In today’s video, I dig into the CAN bus esoterica to give you a look into how it does what it does. This video also tee’s me up for the next ATP, which is a natural extension to the CAN bus topic: OBD2. (spoiler: CAN bus is sort of a subset of OBD2).
