The logic analyzer has always been shrouded in mystery. While most R&D personnel are very familiar with oscilloscopes, they may still be somewhat unfamiliar with logic analyzers. Perhaps you guessed it is an expensive, large instrument with a bulky chassis. Whether right or wrong, at least that’s what I thought when I was in college. … Read more
The motivations for learning microcontrollers can be categorized into four types: firstly, learning for personal interest; secondly, learning for a major; thirdly, learning for a job; and fourthly, learning out of necessity at work. Regardless of the motivation, different individuals may require different learning methods based on their major and the depth of their electronic … Read more
Timing is very important for digital circuits; it can be said that timing is the foundation for the normal operation of digital circuits. When it comes to timing, it generally refers to the programming methods of programmable devices. In microcontroller programming, it is necessary to write programs based on the timing of the controlled chip, … Read more
Looking at the history of version control systems, or code management systems, it can be roughly divided into four periods, with the following mainstream tools corresponding to them: 1980: RCS 1990: CVS, VSS, Perforce 2000: SVN 2005: Git Undoubtedly, Git is the mainstream tool used for source code management today, initiated by the father of … Read more
At this time, some people worry about where to go for fun, some worry about not being able to buy tickets, some worry about not being able to book rooms, some worry about not having money to go out, and some are even worse… they don’t get a holiday at all. Last night I had … Read more
MAKER：jocomakerspace / Translated by: 趣无尽 This project introduces a drawing machine that can draw large-scale graphics directly on an upright canvas, making the drawing process quite visually appealing. The core system is built using a Raspberry Pi and supports receiving patterns via WIFI. First, let’s take a look at a test video. Materials List HardwareNEMA … Read more
If you want to master the OpenWrt system, you should learn to compile OpenWrt firmware yourself, and even learn to add your own small features to the OpenWrt system. Many people have encountered situations where the OpenWrt firmware they compiled does not have a web interface, so they start trying various methods to find the … Read more
With the application of cloud computing, big data, and artificial intelligence technologies, relying solely on CPUs can no longer meet the computational needs of various industries. Scenarios such as massive data analysis, machine learning, and edge computing require a diversified computing architecture, necessitating the collaboration of different processor architectures and heterogeneous computing technologies like GPUs, … Read more
