Implementation of Communication Protocols in Industrial Automation Using C Introduction With the development of industrial automation, the demand for communication between various devices, sensors, and control units is increasing. In this context, communication protocols have become an essential foundation for data exchange among different systems. The C language, with its efficiency and low-level characteristics, is … Read more
Optimizing Program Size in Embedded C/C++ Development: Structure Optimization In <span>C</span> and <span>C++</span> programming, the memory layout of structures (<span>struct</span>) has a significant impact on program performance and memory usage, especially in embedded development where <span>RAM</span> is limited to <span>16K</span>, <span>8K</span>, or even <span>4K</span>; every byte counts, and there is no room for waste. This … Read more
Introduction For development on Windows, many IDEs integrate compilers, such as Visual Studio, providing a “one-click compile” feature, allowing the user to compile, link, and generate target files with just one operation after coding. Linux development differs from Windows; the gcc/g++ compiler is generally used in Linux. If developing Linux programs for ARM, the arm-linux-gcc/arm-linux-g++ … Read more
Generally speaking, a makefile is a file that defines one or more execution rules and methods and is executed by the make command. This section will provide a simple and direct explanation of makefile and illustrate its application in the IC design simulation process. Makefile Definition The rules for writing a makefile are as follows: … Read more
When compiling the Linux kernel, we often execute some commands in the top-level directory of the Linux kernel. Taking RK3288 as an example, commands include: make firefly-rk3288-linux_defconfig, make menuconfig, make firefly-rk3288.img, make zImage, etc. Without delving into the specific meanings yet, I would like to raise a few questions. (1) The Linux kernel is so … Read more

Source: Baiwen Technology ❞The Linux kernel source code files are numerous, and it’s hard to understand the relationship between Makefile, Kconfig, and .config. Without understanding the kernel compilation system, it can be difficult to compile and modify the kernel, integrate your own drivers, or configure the kernel. These issues are all related to Makefile, Kconfig, … Read more
1. Introduction In the Linux device driver model, a bus is an abstract concept, a special type of device. In the implementation of the device model, the kernel specifies that each device in the system must be connected to a bus, which can be an internal Bus, a virtual Bus, or a Platform bus. The … Read more
