Problems solved by technology

[0002] Due to the limitation of software and hardware resources of the embedded system, the operating system usually cannot directly provide a suitable personalized and humanized operation interface
The traditional human-computer interaction method based on the combination of keyboard and LCD display mostly implements menu operations through function nesting. This method requires developers to have a deep understanding of keyboards, LCD displays, data interfaces, etc., so maintenance costs Large size and complex maintenance methods are not conducive to rapid product iteration

Embodiment Construction

[0031] Below in conjunction with accompanying drawing, illustrate the specific embodiment of this invention. The data structures described in the embodiments are implemented in C language, but C language is not the only way to implement the data structures.

[0032] Step 1: Build the submenu structure, as follows:

[0033]

[0034]

[0035] In the above submenu structure, name is the display name of the menu, type is the type of the menu (function or cascade), ptr is the multiplexing pointer pointing to the cascade menu or function function, byfunc is the menu preprocessing function (used to enter the menu Previous operations, such as inputting a password, etc.), vfunc is a menu post-processing function (used to store the data of the user's operation, etc.).

[0036] Step 2: Build a single-level menu array, as follows:

[0037]

[0038] The single-level menu array type is sMenuArray structure. The content of the array is an array of menu items to be displayed. The...

Abstract

The invention relates to a convenient method for realizing multi-level menu construction and display based on a hybrid data structure of a linked list, a tree and an array in an embedded system. By use of the method disclosed by the invention, a sub-menu structural body, a single-level menu array for constructing a sub-menu, a tree structure for constructing the multi-level menu, a structural body for recording a selected menu, a linked list for recording an array mode of a menu selection path, and a group of expression functions for maintaining above mentioned data structures are constructed; the group of expression functions provide the running software environment of the mentioned multi-level menu of the invention. The construction and display of the multilevel menu can be rapidly and conveniently realized by use of the method disclosed by the invention, the addition, deletion, and shifting and other operations can be conveniently and rapidly performed on the individual menu and the single-level menu. The software and hardware development environments in different types are isolated from each other through an abstract data structure, so that the convenience, the fastness, the individuation and humanization of the menu maintenance are realized.

Description

technical field [0001] The invention relates to a construction and display method of a multi-level menu in an embedded system, in particular to a method for realizing multi-level menu construction and display based on a mixed data structure of a linked list, a tree and an array. Background technique [0002] Due to the limitation of hardware and software resources of the embedded system, the operating system usually cannot directly provide a suitable personalized and humanized operation interface. The traditional human-computer interaction method based on the combination of keyboard and LCD display mostly implements menu operations through function nesting. This method requires developers to have a deep understanding of keyboards, LCD displays, data interfaces, etc., so maintenance costs Large size and complex maintenance methods are not conducive to rapid product iteration. Contents of the invention [0003] In view of the above problems, the present invention provides a...
