According to reports from Electronic Enthusiast Network (Written by Wu Zipeng), motors play a core role in modern industry, serving as a key device for converting electrical energy into mechanical energy. They are widely used in various machinery, household appliances, transportation, and industrial automation. The precision and flexibility of motors directly influence the intelligence and … Read more
Introduction: Recently, I have been working on data processing related to acceleration, needing to integrate acceleration into displacement. I found that there isn’t much information available online, so I will summarize what I have done recently! There are mainly two methods for integration: time-domain integration and frequency-domain integration. A common issue with integration is the … Read more
Numerical Analysis 2.1 Differentiation The diff function is used to compute the differentiation of a function, with the following four related syntaxes: diff(f) returns the first derivative of f with respect to the predefined independent variable. diff(f, ‘t’) returns the first derivative of f with respect to the independent variable t. diff(f, n) returns the … Read more

Today, we will delve into how to scientifically plan and implement a … Read more
As transistor sizes approach the nanoscale and even atomic scale, 3D stacking has become a key factor driving the development of the semiconductor industry, particularly in high-performance computing and artificial intelligence (AI) applications. However, 3D integration introduces numerous thermal management challenges associated with increased power density and constrained heat dissipation paths, especially through low thermal … Read more
Creating a Cortex M7 Filelist When we obtain the code package from the vendor, we first copy all the code to the working path. Remember to copy, not cut, to maintain a source. This is to ensure that after we finish, we have a reference for any modified code, fostering a habit of leaving traces … Read more
On one hand, it is considered unfavorable because chip manufacturers are viewed as prestigious companies in the industry, while modules are produced by downstream customers. As the integration of chips increases, the barriers to entry for modules are becoming lower. Therefore, when chip manufacturers start producing modules, many see it as a waste of “personnel … Read more
In the previous article, we introduced the first two characteristics of FPGA: hardware programmability, parallelism, and real-time capabilities, and discussed the numerous opportunities these characteristics present. In this article, we will continue to introduce the other two characteristics to complete the four main features of FPGA and its survival opportunities. Four Main Features and Survival … Read more
Recently, I came across a teardown article by a netizen about a gas alarm, which features a simple circuit structure that differs from the power integrated chip solutions we usually see. The following image shows the teardown of the gas alarm.This solution steps down AC220V through a transformer to a secondary voltage of 10V, and … Read more
Traditional factory equipment communication is complex, and the interconnection costs between different brands of PLCs are high? Apache PLC4X provides a perfect solution for the Industrial Internet of Things. It supports various PLC protocols with a unified API call, making “interconnectivity” in the industrial control world possible. Open-source, free, and secure, this tool makes the … Read more
