I have always liked single-chip microcomputers and wanted to develop in this field, but I have been blocked everywhere when looking for a job. I only know 51 single-chip microcomputers now, but I am s...
The most common shape of electric scooters is the L-shape, with an integrated frame structure and a minimalist design. The handlebars can be designed to be curved or straight, and the steering column ...
Question 1: How does MOV affect CPSR? Question 2: To verify a conjecture that BX uses the last bit to mark the state switch. The program code is as follows: AREA EX,CODE,READONLY ENTRY MAIN ADR RO,THU...
An embedded operating system is needed in the project. Considering free and open source, I first thought of freeRTOS. I just used it before and didn't care about the porting. Today I spent some time p...
Abstract: Three-level rectifiers have attracted more and more attention due to their unique advantages. The working principle of three-level bridge rectifiers is introduced, and its control system is ...
1. Overview
Will passive devices
produce nonlinear intermodulation distortion? The answer is yes! Although there is no systematic theoretical analysis, it has been found in engineerin...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]

1 Introduction
With the improvement of people's quality of life, lamps are no longer just basic indoor lighting tools, but also a kind of practical art for architectural decoration. When ther...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]
Overview
By transmitting ultrasonic energy into the human body and receiving and processing the returning reflected signals, phased array ultrasound systems can generate images of organs and s...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
