Software Development Process: (1) Create a project, specifying the location of source files, compilation targets, memory configuration, and compilation options. (2) Add files to the project. (3) Set project options, such as compiler optimization options, memory mapping, and output file types. (4) Compile and link. (5) Flash programming, downloading the program to flash memory. (6) … Read more
Can you scan the world without scanning a single code? More Recommendations Still struggling with migration? This article clarifies the principles and calculations of level measurement.
This is a further refinement of the Cortex-M3 programming model, covering more specific implementation details and key operations: 1. Refinement of Register Groups 1. Detailed Explanation of Special Registers CONTROL Register (32 bits, modifiable only at privileged level) Bit 0 (`nPRIV`): 0 = Privileged mode (can access all resources) 1 = Unprivileged mode (restricted access) … Read more
In embedded system development, the GCC toolchain is an indispensable core tool. It is not just a set of compilers but also supports the entire process of building, debugging, and optimizing programs. This article will systematically introduce you to the various components of the GCC toolchain, its working mechanisms, debugging and optimization techniques, along with … Read more
Overview of Simplified Segment Definition In assembly language programming, the new version of the assembler provides a method for simplified segment definition, which is more convenient compared to complete segment definitions. The simplified segment definition automatically handles segment attributes through predefined storage models, significantly reducing the burden on programmers. Core Advantages of Simplified Segment Definition: … Read more
0x00 This article is dedicated to daily learning and note sharing to help everyone learn assembly language. Why learn assembly language? Because in red-blue confrontations, our tools are often detected and killed by some AV/EDR. Therefore, we need to counter AV, which is the evasion technique. To learn evasion techniques, we must start from the … Read more
Setting Breakpoints and Monitoring Variables in C++ In C++ development, debugging is a crucial step. By setting breakpoints and monitoring variables, we can better understand the execution flow of the program and quickly locate issues. This article will detail how to use breakpoints and variable monitoring in C++, along with corresponding code demonstrations. What is … Read more
Custom Code Implementation Using C++ Conditional Compilation In C++, conditional compilation is a powerful feature that allows programmers to selectively include or exclude code based on specific conditions. This is particularly useful in scenarios such as cross-platform development, debugging, and version control. This article will detail how to use conditional compilation to achieve code customization, … Read more
1. Introduction In embedded system development, the HardFault exception of Cortex-M microcontrollers is one of the most challenging issues. When the system encounters a severe error that cannot be handled, it triggers a HardFault interrupt, causing the program to stop running. This exception is often caused by memory access errors, stack overflows, illegal instruction executions, … Read more
Firmware is an integral part of any embedded system. Devices are not just a combination of components. Without instructions, a microcontroller “does not know” how to manage peripheral devices. However, embedded firmware development is not an easy task. It involves not only coding but also extensive testing and debugging. Today, we will discuss the common … Read more
