For a long time, the embedded industry has been constrained by CPU performance, ROM and RAM capacity and other factors, so the software scale cannot be built too large. The new embedded designers often overturn the original version because they cannot comprehend the previous code. The lack of software framework standard leads to redundant and useless work. By making the analogy to the hierarchical idea of Android architecture, this paper proposes a simple and practical software architecture suitable for the embedded industry. The architecture adopts hierarchical design and each module operates independently, thus realizes high cohesion and low coupling of the system. The C structure variable is used to simulate the properties of the class, and the function pointer is used to replace the function in the class. By doing this, embedded programming changes from process-oriented to object-oriented. In addition, the architecture provides a registration mechanism to solve the upload of high-speed, real-time changing data. |
