Single-chip microcomputer program construction method based on layered architecture thought

Abstract

The invention discloses a single-chip microcomputer program construction method based on a layered architecture idea, and relates to the technical field of computers. When a single-chip microcomputer program is constructed, layered construction is adopted and comprises an equipment layer, a service logic layer, a transmission protocol layer, a communication interface layer, a hardware abstraction layer and a physical layer from top to bottom; the internal data of the program is transmitted from the business logic layer to the physical layer downwards layer by layer or transmitted from the physical layer to the business logic layer upwards layer by layer, and each layer only exchanges data with the adjacent layer through the API of the module object. According to the single-chip microcomputer program construction method based on the hierarchical architecture idea, the code hierarchical structure is clear and easy to read; layering and modularization realize weak coupling of codes, so that program codes are easy to expand and modify.

Description

technical field [0001] The invention belongs to the technical field of computers, and relates to a single-chip microcomputer program construction method based on the idea of ​​layered architecture. Background technique [0002] Generally speaking, compared with computer programs, single-chip microcomputer programs are less complex, but this does not mean that single-chip microcomputer programs do not require architectural design. At present, when many software engineers write single-chip microcomputer programs, they often "mix" the business logic code with the underlying code such as data analysis, and the program code is strongly coupled. The code written in this way has the following disadvantages: (1) The code is not easy to read; (2) ) The code is not easy to expand; (3) The code is not easy to modify; (4) It is not easy to work in a team; therefore, it is necessary to develop a single-chip program construction method to standardize the development of single-chip program...

At present, when many software engineers write single-chip microcomputer programs, they often "mix" the business logic code with the underlying code such as data analysis, and the program code is strongly coupled. The code written in this way has the following disadvantages: (1) The code is not easy to read; (2) ) The code is not easy to expand; (3) The code is not easy to modify; (4) It is not easy to cooperate in a team; therefore, it is necessary to develop a method for building MCU programs to standardize the development of MCU programs
