Today, I will share with you the hardware UART peripheral debugging output mechanism under IAR. In the embedded world, outputting print information is a very common auxiliary debugging method. With the help of print information, we can easily locate and analyze program issues. There are many ways to implement print information output in embedded application … Read more
Many people do not know how to write programs by looking at timing diagrams. Below, we will analyze a non-standard I2C device and teach everyone how to write an efficient IO simulation of I2C timing. Observing the timing diagram, it includes the I2C start signal, I2C stop signal, I2C acknowledgment, non-acknowledgment, response acknowledgment, as well … Read more

Today, let’s talk about ARM bare-metal development. Many beginners feel overwhelmed when they see ARM, thinking it’s particularly difficult. In fact, it’s not; once you grasp the essentials, writing a simple LED … Read more
For training, consulting, or project development, please contact 【Thought】 Readers of this public account must be familiar with the CAN communication protocol. Have you ever wondered how these signals are implemented in the communication protocol within the Electronic Control Unit (ECU) when collecting CAN bus signals and analyzing data? This content introduces how to implement … Read more
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
The Linux kernel source code contains numerous files, and understanding the relationships between Makefile, Kconfig, and .config is crucial for navigating the kernel compilation system. Issues arise when trying to compile and modify the kernel, integrate your own drivers, or configure the kernel. All of these problems relate to Makefile, Kconfig, and .config. Below, I … 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
