The degree of electronicization in automobiles is an important indicator of modern automotive standards, and the advancement of automotive electronic technology has also driven the development of bus technologies. Traditional automotive electronics use point-to-point communication methods, with no connections between units, resulting in the need for massive wiring harness systems for the entire vehicle. From … Read more
Before discussing buses, we should first understand what a bus is. According to the complete definition from Baidu: A bus is a common communication line for transmitting information between various functional components of a computer. It is a transmission line composed of wires, categorized according to the type of information transmitted by the computer. In … Read more
The automotive bus we are most familiar with is CAN, while LIN and FlexRay may be somewhat unfamiliar to many. Next, let’s introduce these four types of automotive buses. The automotive bus is the communication network that connects the lower-level automotive devices or instruments within the vehicle.Currently, there are four mainstream automotive buses: CAN bus, … Read more

Recently, I saw some netizens discussing whether ‘CAN is more difficult than UART’ in a technical group. Some netizens said CAN is very simple, while others said CAN is very difficult. In fact, whether it is difficult or not mainly depends on your perspective. Some netizens may have a good foundation and have studied CAN, … Read more
1. SPI BusThe Serial Peripheral Interface (SPI) bus technology was introduced by Motorola and is a synchronous serial interface. Most MCUs (Microcontrollers) produced by Motorola, such as the 68 series MCUs, are equipped with SPI hardware interfaces. SPI is used for full-duplex, synchronous serial communication between the CPU and various peripheral devices. SPI can simultaneously … Read more
Bus Buses are everywhere. Signals in this world are the same, but there are thousands of buses, which can be quite confusing. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses connect various peripheral chips with the processor within a microcomputer; system buses connect plug-in boards with … Read more
In embedded development, interfaces such as UART, I2C, and RS485 are commonly used. Understanding them may be ambiguous, so this article organizes them. The article is lengthy, with an estimated reading time of about 10 minutes. UART (Universal Asynchronous Receiver-Transmitter) The UART port refers to a type of physical interface (hardware). UART is an asynchronous, … Read more
