The controller area network (CAN) serial-bus topology allows devices and microcontrollers to communicate with each other without the use of a host computer.What is the CAN bus protocol? The Controller Area Network is a message-based protocol designed to allow the Electronic Control Units (ECUs) found in today’s automobiles, as well as other devices, to communicate with each other in a reliable, priority-driven fashion.Meaning, each ECU can take control of the bus and broadcast information (such as sensor data) over it.I am new to this forum, so I want to take the opportunity and say hello to everybody.

The TJA1050 CAN PHY can’t be used to make a passive CAN hub/repeater.The confusion lies in what the work energy theorem says and what it doesn’t say.As shown in Figure 2, the driver is recessive when both the high- and low-side transistors are off and in a high impedance state. Before we proceed, it is useful to know that multiple variants of CAN exist: Low-speed CAN: Fault-tolerant CAN is a low cost option when fault tolerance is critical – but is increasingly replaced by LIN bus High-speed CAN: Classical CAN is the most common variant today across automotives/machinery (and the focus of this article)ECUs are connected to the bus in a multi-master configuration.Recently I had a discussion whether one could use RS-485 transceivers for a CAN-bus network in order to gain the flexibility to use the same hardware either in a CAN-environment or in half-duplex RS-485 network, albeit with different software.VIDEO ANSWER: The first, second, and third variables are equal to 13 negative 5, 2 negative 2, 9, and 13 point, and the second, third, and fourth variables are .
