For many beginners, it’s definitely puzzling why … Read more
来源 | 吃时间的虫子TK Software engineers typically need to determine which data structures and algorithms to use based on specific application business logic. It can be said that suitable data structures and algorithms are the cornerstone of stable business software operation. If you are a software engineer, whether you are preparing for coding interviews, optimizing your … Read more
GPIO (General Purpose Input/Output) is a pin on a microcontroller or microprocessor that can be programmed as an input or output for communication with external devices. In Linux systems, developers can easily read and set the state of GPIO through user space interfaces provided by the kernel, enabling control and monitoring of external devices. This … Read more
Hello everyone, I am Pi Zi Heng, a serious technical guy. Today, I will talk about disassembly files in embedded development (.s, .lst, .dump). In the fourth, fifth, and sixth lessons, I introduced three types of output files generated by the compiler/linker (relocatable, map, executable files). These three files focus on how the compiled/linked code … Read more
Hello everyone, I am Pi Zi Heng, a serious techie. Today, I will talk to you about map files in embedded development. In the fourth lesson, I introduced the first type of output file – relocatable files. This article continues to discuss the second type of output file generated by the project – map files. … Read more
Hello everyone, I am Pi Zi Heng, a serious tech enthusiast. Today, I will discuss linker files in embedded development. In the previous lesson “Source Files (.c/.h/.s)”, I systematically introduced source files, which are typical input files in embedded projects. But are there other types of input files? Since I asked this question, the answer … Read more
Hello everyone, I am Pi Zi Heng, a serious tech person. Today, I will talk about project files in embedded development. In the previous two lessons, I introduced two typical input files in embedded development: source files (.c/.h/.s) and linker files (.icf). I want to ask again, are there any other input files? The answer … Read more
