![]() ![]() We could buy any of the plug-and-play Arduino CAN shields, but building the hardware ourselves is easy, more fun and cost reduction, bro.ĬAN H: CAN High and is connected to the CAN High wire of the bus.ĬAN L: CAN Low and is connected to the CAN Low wire of the bus. ![]() You can continue reading about CAN from wiki as it really gives a very good and sufficient introduction to the topic. One of its greatest advantages is that it connects any number of ECUs (or microcontrollers) in your car through the two-wire bus, CAN High and CAN Low, reducing the weight of wires that could be gained by using point-to-point communication between ECUs.Įnough talking and let's grease our hands! The first 3 steps are the basic ones that will initiate a CAN BUS at your home, the rest of the steps are a little bit advanced and real-life CAN situations.ĬAN BUS is a two-wire, half-duplex communication protocol that is widely used in Automotive industry. I will try to keep it as easy and concise as possible to get you straight to a properly working setup, saving your time for further developments afterwards. ![]() This Instructable is trying to summarize what I ended up with after a long time of search, tutorials, trials and datasheets to build a functional CAN BUS node. ![]()
