In addition to the release of the iPhone 8 series of mobile phones, Apple also released the latest Apple Watch Series 3 at this conference. It has a second-generation OLED Force Touch retina screen. L...
The development of motherboard power systems has always encountered many challenges in terms of cost and performance, especially the CPU main processor power supply (Vcore) control. In the past few ye...
The characteristic of this module is that the link budget is maximized, and the direct line of sight distance in the wild can reach 700 meters.Same power consumption, longer communication distance.Tec...
I am currently using C8051F340 to transfer data between USB and PC. Many people say that USBXpress makes development very convenient. After I installed it, I still don't quite understand how to use it...
[align=left][font=Tahoma][size=10.5pt]The core of STM32 Cortex-M3 processor is a standardized microcontroller structure. I hope you can think about what is standardization? In short, the Cortex-M3 pro...
RT. I have wanted to get in touch with embedded systems for a long time. I don't like uCOS. Maybe there is no one around to teach me. I don't know what everyone is using. Maybe my knowledge reserve wa...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]

In public places such as schools, government agencies, factories and mines, as well as public corridors in residential areas, the phenomenon of long-burning lights is very common, which causes a h...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
Since the late 1990s, with the demand for higher system efficiency and lower power consumption, the technological update of telecommunications and data communication equipment has promoted the deve...[Details]
This article will introduce a design method for a distributed control system used in a tracking car, which can perform distributed control of motor modules, sensor modules, and lighting control mod...[Details]
The DisplayPort interface standard is approved by the Video Electronics Standards Association (VESA) to provide an open, scalable standard for the entire industry. The development of DisplayPort ca...[Details]
Among the uses of electrical energy, lighting accounts for a considerable proportion. Compared with the earlier ordinary incandescent lamps, the fluorescent lamps and energy-saving lamps we commonl...[Details]
The production process of lithium batteries does not mention the previous processes such as material preparation, winding, liquid injection, and packaging, but only talks about the final formation ...[Details]
