Method, system, device and storage medium for layered design of software based on single chip microcomputer

Abstract

The invention discloses a method, a system, a device and a storage medium for layered software design based on a single chip microcomputer, wherein the method for layered software design based on thesingle chip microcomputer comprises the following steps: the single chip microcomputer software of each target device is divided into an application layer, a function layer, a driving isolation layerand a driving layer; an interface of the drive isolation layer of each target device is unified as a first standard interface; an interface of the function layer of each target device is unified as asecond standard interface; the second standard interface and the first standard interface of each target device are called to realize application service. The invention divides the MCU software of thetarget device into an application layer, a function layer, a driving isolation layer and a driving layer by a layered design method. At the same time, the interface of the driving isolation layer isunified into the first standard interface, and the interface of the function layer is unified into the second standard interface. Therefore, the transplantation across hardware platforms can be realized, and the portability, confidentiality, maintainability and practicability of the software code of the single chip microcomputer can be improved.

Description

technical field [0001] The invention relates to the field of single-chip microcomputers, in particular to a method, system, device and storage medium based on single-chip microcomputer software layered design. Background technique [0002] With the continuous development of computer technology, the application of single-chip microcomputer is becoming more and more extensive, and it is more and more inseparable from our life. Various electronic products, digital products, smart IC cards, industrial automation control, data processing, etc. are widely used in single-chip microcomputer . The traditional single-chip software development is based on the driver and application mode. The application layer directly calls the underlying interface function of the driver layer to realize the application function, which causes the code coupling between the application layer and the driver layer to be relatively large, and it is not easy to separate. Suppose system A is composed of appl...

Problems solved by technology

Similarly, when it is necessary to transplant the driver layer in different systems, it is also necessary to rewrite the code, which makes the portability and maintainability of software applications and drivers poor, resulting in waste of time and cost

If the driver layer and the application layer are compiled together, the respective codes will be disclosed to each other. It cannot be completely isolated and kept secret, and it is easy to leak the company's core technology.
