Friends with a bit of computer knowledge must know that computers only recognize 0 and 1. Back in the day, to write a program, you had to use 0 and 1, haha, cool, right? So, the admiration for programmers might have originated from that time. Later, people found it too inconvenient to write programs using … Read more
1. Two Ways of ARM Assembly Development ARM assembly development refers to the use of ARM-provided assembly instructions for ARM program development. There are two ways of ARM assembly development: one is using ARM assembly, and the other is using ARM GNU assembly. The assembly instructions used in both development methods are exactly the same; … Read more
Assembly Language, for those who have never delved deeply into it, can be incredibly arcane. Since our computers are developed based on assembly language, understanding this content will greatly help us clarify how the CPU works. The X86 computer is fully backward compatible with the IBM PC – from the top level of the system … Read more
1. Embedding Assembly Language in C In microcontroller development, we usually write the main program in C language, which allows us to fully utilize the mathematical libraries and powerful data processing capabilities provided by C language tools. However, the controllability of C language is not as good as that of assembly language. For some time-sensitive … Read more
In assembly language, there are specific instructions to output high or low levels on a certain port. Taking port P1.0 as an example: The instruction to set this port to high is: SETB P1.0 The instruction to set this port to low is: CLR P1.0 Now, we will connect a small light to the microcontroller’s … Read more
In the manufacturing of printed circuit boards (PCBs), the PCB assembly technology has emerged to improve production efficiency, reduce costs, and optimize material utilization. Below, we will briefly introduce three common methods of PCB assembly, hoping to be helpful to everyone. Generally speaking, PCB assembly refers to the practice of circuit board manufacturers connecting smaller … Read more
This article is reprinted from the Extreme Community Extreme Column: Agile MM32 MCU Author:Nuoeriris The Arm processor is designed based on the principles of Reduced Instruction Set Computing (RISC). The instruction set and associated decoding mechanisms are relatively simple, featuring a 32-bit Arm instruction set and a 16-bit Thumb instruction set. The Arm instruction set … Read more
For those familiar with computers, the BIOS (that blue interface) may not be too strange, as it is the startup code for the computer. Without BIOS, a computer is destined to be a brick! The BIOS mainly does some preparatory work before booting, such as setting the system time and boot order… but I digress. … Read more
I. Embedded 1 Form Analysis Embedded refers to a joining method where a block on one component slides into a groove of another component. The blocks are typically in a “7” shape, with the initial groove being the first groove and the groove where it slides in being the second groove. The width of the … Read more
