Having referenced various embedded books available on the market, including MCS-51, AVR, ARM, etc., I have not found any that introduce design concepts. Even if such books exist, they are rare. Writing programs is not difficult, but writing them well and quickly requires some experience accumulation. The idea of structured and modular program design is … Read more
The concept of 3D printing is certainly familiar to fans of Guokr. It originally refers to the process of “sequentially depositing materials using a powder layer inkjet print head,” and has now integrated various technological methods such as extrusion and sintering. With the continuous advancement of technology, the speed of 3D printing has also increased, … Read more
1. What Is Hardware? In other words, hardware is physical, at least something you can see and touch. It is a material carrier, the material basis. Broadly speaking, humans live on a material basis, and you can refer to everything you can see as hardware. Of course, in a narrow sense, software and hardware generally … Read more
What is Hardware In a narrow sense, software and hardware generally refer to the electronic field. Software code is also written by people, and the languages we are familiar with, such as C, C++, etc., are translated into assembly language by compilers, and then assembly language is translated into binary machine language by assemblers, which … Read more
Product reliability is designed. It is produced and managed. －Qian Xuesen 1. Circuits Are Designed. Don’t Just Draw, Be a Designer. An electrolytic capacitor soldered next to a heat sink causes the related circuit parameters to drift, resulting in unstable machine parameters; the inconsistency in the color of green LEDs makes them look unattractive. Each … Read more
