The increasing scale of code and multi-threading technology based on RTOS has made embedded software development more focused on “concurrency control and thread safety.” When multiple execution threads (referring to any context running code, including threads and interrupt service routines) need to access the same shared resources (including software data and hardware resources), errors may … Read more

In modern software development, embedded scripting languages are widely used to extend the functionality of applications, especially in scenarios requiring dynamic interaction. For C++ developers, ChaiScript is an excellent embedded scripting library that provides a simple and easy-to-use interface while seamlessly integrating with the C++ language. What is ChaiScript? ChaiScript is an embedded scripting language … Read more
1. Singleton Pattern The Singleton Pattern ensures that a class has only one instance and provides a global access point. Core structure diagram of the Singleton Pattern: The structure typically includes: A private static instance (pointer to itself) A private constructor (to prevent external instantiation) A public static method (to get the unique instance) In … Read more
In embedded system development, the <span>printf</span> function is like an old friend, facilitating debugging and information output. However, the standard library’s <span>printf</span> is often too large, consuming precious memory resources, which is a heavy burden for resource-constrained embedded systems. Today, we are excited to introduce a lightweight and efficient <span>printf</span> library—lwprintf—that will completely change your … Read more
FreeRTOS Tasks Let’s continue Bob’s open-source FreeRTOS series articles. The core of FreeRTOS is the task. In this second part, I will explore what a task is, what options are available to configure the Task Control Block (TCB), and what functionalities might be missing in the FreeRTOS TCB. As I grew up, I gradually discovered … Read more
