After working with microcontrollers, I transitioned to ARM and initially used the ADS 1.2 compiler. I used it for a while because the old program of the project I took over was compiled with ADS, and most of the department was using it. When learning about microcontrollers, I used the Keil C51 compiler, and the … Read more
Do you know how the programming languages you often use are implemented? Today, let’s talk about this question. Smart humans discovered that by combining simple switches, they could express complex boolean logic. Based on this, they built the CPU, which can only understand switches in a simple way, represented numerically as 0 and 1. The … Read more

In the first class, the teacher asked students to write a blog about the first lesson as an assignment. I was quite surprised by this novel … Read more
2.2 Fundamentals of Language Processors A language processor is a type of system software that translates programs written in high-level languages or assembly languages into machine language programs so that they can run on computers. Language processors are mainly divided into three basic types: assemblers, compilers, and interpreters. 2.2.1 Basic Principles of Assemblers 1. Assembly … 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
Basic Knowledge Computer Language: The language used for communication between humans and computers is called computer language. Computer languages are divided into high-level languages and low-level languages. High-level languages: Far from hardware. Low-level languages: Close to hardware. Instruction: A command for the computer to perform a certain operation, consisting of a series of binary codes. … Read more
For embedded systems, if there is no RTOS running, the main function main() in program development needs to use some mechanism to keep running happily forever, it has no endpoint. If you want to exit from the main function, what happens specifically is determined by the C language compiler used. 1. Introduction to the Problem … Read more
