5. The functional module also comprises an embedded real-time operating system, a file system, a graphical interface and a corresponding development tool, and is used for providing an operable interface for upper-layer application so as to meet the requirement of rapid development.

The product service logic and UI design development on the PC is as follows:

1. the C language part is operated to provide an environment for the operation of Lua language application, and simultaneously, a hardware control part and service logic are separated through a Lua engine, so that a user service logic script developed by Lua is unrelated to hardware, and the simulation debugging development can be carried out on a PC.

2. A basic development tool VisualTFT of a Lua screen of the cooker is installed on the PC, and UI component callback and hardware operation callback functions related to product service logic are completed by using a Lua script language.

3. Compared with the existing frying machine with large interface development difficulty and complex logic, the Lua script is introduced into the interface development, the Lua script logic development and debugging and the UI component design are carried out on the PC by installing the Lua development tool on the PC, and finally the Lua script logic development and debugging and the UI component design are downloaded to a frying machine screen, so that the program development difficulty is greatly simplified and the program development efficiency is improved. And the service logic interface can be standardized and modularly designed, so that the user requirement for facilitating the rapid development of products is met, and the development difficulty is reduced.
