Examples of CAN Applications Bus Topology Diagram The CAN controller determines the bus level based on the potential difference on the two wires. The bus level is divided into dominant and recessive levels, one of which must be present. The sender sends messages to the receiver by changing the bus level. Connection diagram of CAN … Read more
Overview of CAN CAN is an abbreviation for Controller Area Network (hereinafter referred to as CAN). CAN belongs to the category of field buses, and it is a serial communication network that effectively supports distributed control or real-time control, known as the computer local area network in the field of automation. The CAN bus is … Read more
CAN, short for “Controller Area Network”, is one of the most widely used field buses internationally. Initially, CAN was designed for microcontroller communication in automotive environments, exchanging information between various electronic control units (ECUs) in vehicles, forming an automotive electronic control network. For example, the engine management system, transmission controller, instrument equipment, and electronic backbone … Read more
When learning about in-vehicle testing, how can we not understand CAN basics? Today, I have organized a detailed note for everyone, so let’s follow along with Songqin! Understanding CAN 01 What is CAN Bus? CAN stands for Controller Area Network, which is an internationally standardized serial communication protocol by ISO. In simple terms, the CAN … Read more
The RS232 type DB9 interface, which used to be found on older computers, can be connected to modems. In MCU51 microcontroller projects, this UART interface is generally used, with serial port rates of 115200bps, 57600bps, etc. Later, USB to serial converters like PL2302 and FT232 emerged, with rates reaching up to 921600bps, which is considered … Read more
