A graphical cloud development platform, comprising:

and the script program generating module is used for generating a script program according to the graphic programming datagram, and the script program is used for driving the script interpreter executable file.

In this embodiment, the plug-in making module provides a plug-in file uploading interface and a plug-in making page, and can make a plug-in file by filling content in the plug-in making page and sending the filled data to the server; the plug-in file uploading interface is a webpage and server interaction interface, and local plug-in files can be uploaded to the server through the interface, so that the requirement of a user for offline plug-in file production is met.

In this embodiment, the plug-in file includes one or more plug-in function contents, and each of the plug-in function contents includes four core data: function code (C language SDK code), interface usage (C language API generated information), function description, and display effect.

Each core data is composed of one or more passwords and a plurality of members corresponding to each password, and each member comprises one or more of codes, fields and characters; the password is used to determine the role and processing method of the corresponding member.

When the plug-in processing module analyzes and processes the plug-in file, the plug-in processing module only needs to position according to the password and execute corresponding processing functions on the appointed block, the requirement on the specific format of the plug-in is reduced, a modularized effect is obtained, the process of positioning the inside of the program is more convenient and faster, and the modification of the plug-in file is more convenient. Meanwhile, if the plug-in file is designed according to a fixed format, if the plug-in rule is adjusted in the future, the whole plug-in processing module needs to be modified in a large range, which is very inconvenient, and if the password is used, the password and the processing mode thereof need to be increased or the corresponding password area needs to be modified according to the actual adjustment, which is more efficient.

For example, there are three kinds of passwords originally set by one program, but when a new function needs to be added and a fourth password needs to be set, the original script program can still run on the new script interpreter without conflict after the addition.

In this embodiment, the plug-in file is divided into a bottom plug-in directly related to the chip or development board characteristics and an algorithm plug-in not directly related to the chip, and the bottom plug-in has a purpose of solving the following problems: the compatibility problem exists in different chips or development boards due to the characteristics of clock, memory size and the like, or the bottom layer characteristics or functions which need to call chip internal registers and operate accurate addresses in the chips.

The manufacturing requirements of the bottom layer insert are as follows: the bottom layer plug-in requires that on the basis of four core function contents required by the plug-in function of the plug-in file, at least information which influences code compatibility for a chip, crystal oscillator configuration and the like is added in a core part form (one or more passwords + corresponding to a plurality of members).

The function code part of the algorithm plug-in only needs to use C language API provided by the official or generated by other plug-in interface usage core parts, and the purpose of the requirement is to prevent the code from being influenced by the underlying characteristics or functions when the algorithm plug-in is manufactured to cause compatibility loss.

The same bottom layer plug-in can be made into a plurality of different chip versions, the functions realized in the bottom layer plug-ins are the same, the API is the same, the function code core part is different in realization, and the bottom layer plug-ins are regarded as the versions of the same plug-in on different chips. The plug-in is manufactured according to the requirement, and the compatibility of the plug-in during multiplexing is improved.

And the plug-in making page packages the input content in a plug-in file format and sends the packaged input content to the server.

And inputting the member part of each core part in the input field, and combining the member part of the input field with the corresponding password to generate the plug-in file.

In this embodiment, the plug-in file processing module is configured to parse and process the plug-in file, generate a corresponding SDK package and JSON datagram, and record corresponding information in a database, and specifically includes:

extracting member contents of the interface usage according to the password, generating C language API information, recording and storing the C language API information in a database in a data table mode, and generating graphic interface attribute information and temporarily storing the graphic interface attribute information; the API can be recorded in a data table form, so that the speed of calling API information in post processing can be increased, and the occupation of server resources can be reduced; by calling the API of the SDK to compile the program, the SDK can be preprocessed and compiled, and meanwhile, the method needs less processing when compiling and linking, so that the program compiling time can be effectively shortened, and the occupation of server resources can be reduced.

extracting the member content of the display effect according to the password, generating graphic display effect information and temporarily storing the graphic display effect information; and deleting the plug-in file which is analyzed and completed.

And combining the graphic interface attribute information, the graphic function description information and the graphic display effect information to generate and store the JSON datagram, and recording information in a database. By generating the JSON file in advance instead of processing the plug-in file in real time, the JSON generation time in the later period can be reduced, and the occupation of server resources is reduced.

In this embodiment, the generating, by the script interpreter creating module, a script interpreter executable file and a script interpreter information table according to the selected plug-in and the corresponding SDK package based on the database includes:

and the server generates a plug-in list in the interpreter making module according to the information recorded by the SDK in the database, wherein each plug-in corresponds to one SDK program package. The general introduction of the plug-in and the introduction of the functions inside can be known by looking at the plug-in list.

Because the script program is based on the logic and data relation, the volume of the script program is small, the generation time of the script program can be effectively shortened, the information density of the script program is improved, and the formal operation of the script program from the completion of the manufacture to the downloading and the uploading to the chip is faster than that of the conventional programming compiling and burning mode. Meanwhile, because the script program space is small and the script interpreter program can be provided with Bootloader, the functions of multi-platform portable programming such as mobile phones, panels and the like, IAP and the like can be realized. The script interpreter program file and the script program, and the user can add functions by adding keywords to realize function extension. The conventional programming, compiling and burning mode needs to complete the following work: programming, cross compiling, and burning the c language operable file generated after compiling through a JTAG simulator. In the case of cloud programming, a process of downloading the executable file is added after compiling. The script interpreter executable file is burnt in advance, so that the connection logic of the script interpreter is only required to be packaged into a script program after programming is completed, and compared with cross compiling, the process is quicker, and less information needs to be processed. Then, because we generate fewer messages, the downloading takes less time. Moreover, the Bootloader can be directly used for burning without the help of the jtag, so that the method is more convenient and easy to use.
