In embedded development, a basic logging system can record the program's runtime status, but a powerful logging system can proactively help us discover and diagnose issues. Once the basic functionality is implemented, we can use some advanced techniques to transform the logging system from a passive "recorder" into an active "diagnostic assistant". Hex Dump — … Read more
Scan to FollowLearn Embedded Together, learn and grow together In embedded system development, a logging system is a crucial debugging and diagnostic tool. A well-designed logging system can help developers quickly locate issues, analyze system behavior, and monitor operational status. This article will detail how to develop a fully functional embedded software logging system. Requirements … Read more
Further enhance the digital management system for device management in terms of integrity, usability, and maintainability, focusing on plugin management, database, device communication, configuration, logging, and main window status for functional enhancements.

The program compiled successfully, but crashes at runtime? Exceptions are thrown but the source cannot be found? Learn these runtime error localization techniques to transform your C++ program from “mysterious crashes” to “precise debugging”! 📖 Introduction 🎯 Why Master Runtime Error Localization? Compiling successfully does not equal a correct program! Runtime errors are one of … Read more
Overview A high-throughput, low-latency logging system relies on two key aspects: deferring synchronous write delays to the background (asynchronous) and minimizing memory copies (zero-copy). This article provides engineering-level implementation ideas, reusable code snippets, and performance comparisons, suitable for direct adaptation in production systems. In Short • Decouple log collection (format) from disk writing: the main … Read more
