I need to write a software to read the data from the serial hard disk and separate it according to the standard, display the parameters (such as temperature), and control the registers of external dev...
First of all, I would like to thank eric_wang, Mr. Shao from dcexpert, and eeworld. I received the MicroPython Getting Started Guide three days ago. The first impression I got when I saw the cover was...
[i=s] This post was last edited by ligongxiaobie on 2014-4-22 11:08 [/i] Recently, I am using STM32 to do a pulse counting task. It is very simple, that is, to count the number of pulses within a cert...
PWM is generated by the microcontroller, with a frequency of 20K. After RC filtering, it becomes DC, that is, the voltage at point A is DC voltage.
The problem during debugging is that I don't give PW...

1 Introduction
There have been many studies on the detection and protection of power grid short circuit and line fault. The short circuit, overload and overvoltage protectors on the market have ...[Details]
Single-chip microcomputers are widely used because of their small size, powerful functions and low price. This article introduces the method of designing a micro electronic piano using the AT89C51 sin...[Details]
Today, with energy becoming increasingly scarce, the utilization of natural energy has become the focus of people's attention. Among various natural energies, the endless solar energy is highly fav...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[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]
With the rapid development of the national economy, lifting and hoisting operations are used more and more frequently and widely in various fields of economic construction. China has continuously expl...[Details]
Abstract: In order to realize wireless automatic alarm and monitoring of major safety places, based on the basic principle of pyroelectric infrared sensing, a detector for receiving infrared radia...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[Details]
