Friends with a bit of computer knowledge must know that computers only recognize 0s and 1s. Back in the day, to write a program, one had to use 0s and 1s, haha, cool right? The admiration for programmers likely originated from that time. Later, people found it very inconvenient to write programs using just 0s … Read more
Introduction This article is a summary document I wrote after studying “Principles of Assembly Language”, Chapter 3 of “CSAPP”, and the “x86 data sheet”, as well as after a lot of Googling. It is intended for self-checking and review. I would be honored if it could be of assistance. If there are any errors or … Read more
During the process of microcontroller programming, if a designer can master multiple programming languages simultaneously, then this designer is certainly a very talented individual. However, it is quite challenging to be proficient in Assembly, C, and C++ at the same time. Many beginners encounter obstacles while learning even one of these languages, leading to frustration. … Read more
1. What are the advantages and disadvantages of C language and assembly language in microcontroller development? Answer: Assembly language is a symbolic language that uses mnemonic words to represent machine instructions, making it the closest language to machine code. Its main advantages are low resource usage and high execution efficiency. However, assembly languages may differ … Read more
dATa: Fixed to the first 128 RAM addresses from 0x00 to 0x7F, can be directly read and written using ACC, fastest speed, and generates the smallest code. iDATa: Fixed to the first 256 RAM addresses from 0x00 to 0xFF, where the first 128 are identical to dATa, but accessed in a different way. iDATa is … Read more

With the development of technology, there are more and more electronic products, which make our daily lives easier. Most electronic products have microcontrollers, and microcontrollers achieve functionality by executing software logic. The most suitable programming language for microcontroller programming is assembly language, but the most commonly used and widespread is C language. Why should microcontrollers … Read more
