Abstract The relationships between devices are various forms of derived inheritance, tracing back to a common origin. This article discusses the concept of “device framework” or “device tree” in embedded systems, analyzing its design intent, core design philosophy, implementation principles, etc., using the device framework of the RT-Thread system as an example. Concept of Device … Read more
1. Initial Impressions of Structures in C and C++ A structure (struct) can encapsulate different types of data together, forming a new, more complex data type. For example, in C, if we want to describe a student’s information, such as name, age, and score, we can define a structure like this: struct Student { char … Read more

1 Type Erasure1.1 OverviewC++ is a strongly typed language, but when it comes to abstract design, the hard coding caused by strong typing can become a hassle. This is where we need the help of type erasure technology. Type erasure is a programming technique that allows you to operate on various concrete types through generic … Read more
