Embedded devices need to set parameters during operation, which is often accomplished by a PC. A communication protocol must be designed for both parties, with three representative protocols as follows: As can be seen from the table above, embedded devices generally have limited memory and computational performance, so fixed binary is the preferred communication protocol. … Read more

The HaoCurve tool has been developed for 6 years, and its user base is growing. Every year, many friends provide various suggestions for HaoCurve, leading to an annual increase in the codebase, which has now become so large that it causes lag even when wrapping lines. This isn’t a major problem; the most troublesome part … Read more
Everyone, it’s time to learn again! Today! What spiritual food are we bringing? It’s classes! A class is a collection of objects that have the same attributes and operations, providing a unified abstract description for all objects belonging to that class. It includes two main parts: attributes (data variables) and operations (member functions). In short, … Read more

In the previous article, “Introduction to CMake Build Tool for ESP32,” we introduced the most basic usage of CMake with a “Hello World” program. Today, we will provide a detailed explanation of the CMakeLists.txt file. CMakeLists.txt The CMakeLists.txt file is the core configuration file for the CMake build tool. It contains a series of instructions … Read more
One-Click Three Connections，Continuous Valuable Content! Introduction Guite Embedded focuses on sharing knowledge about embedded software and hardware. 1 First Build – First, execute CMake in the project root directory to generate the Makefile or other build tool files required for the build system. This is typically done by running a command like `cmake /path/to/source`. – … Read more
In C++ project development, the build process can often be cumbersome, especially in cross-platform development. Today, I would like to introduce a powerful build tool—CMake. 1. What is CMake CMake is a cross-platform automated build tool widely used in C++ projects. It is primarily used to manage the software compilation process by controlling the compilation … Read more
