Method and system for realizing CLI command interface on single-chip microcomputer

Abstract

The invention provides a method for realizing a CLI command interface on a single chip microcomputer. The method comprises the following steps: firstly, defining a global variable CLI _ SCAN and calling a performance function information recording structural body USRCMD _ PARA _ STRUCT; receiving login information of the user; identifying an interrupted reading character input from the keyboard and outputting processing information; reading a whole command output result character according to the output processing information; judging the type of the action executed in the next step accordingto the result symbol and returning; responding to the action, executing a performance function matched with the action, and outputting a result; the command is added to a historical command. Based onthe method, the invention further provides a system for realizing the CLI command interface on the single-chip microcomputer, and the auxiliary functions which can be realized by the method comprise user permission setting and TAB key or-key supporting. Completing the commands, checking historical commands and the like. A man-machine interaction interface of a command line interface is realized, so that the configuration, management and test of the embedded single-chip microcomputer are more efficient, and scripts are automated.

Description

technical field [0001] The invention belongs to the technical field of command line interface management of embedded equipment, and in particular relates to a method and a system for realizing a CLI command interface on a single-chip microcomputer. Background technique [0002] Command Line Interface CLI is a way of interacting with a device in text mode. This program allows the user to type in text commands that instruct the computer to perform specific tasks. The CLI consists of several components: User Input / Output, Command Line Editing, History Commands, Completion commands, input parsing, parameter validation and command scheduling / execution, error handling and reporting. CLI has lower system requirements and is more suitable for embedded systems; it also has higher execution efficiency, and only needs to type some characters to complete the configuration and management of the device. [0003] In the prior art, there is no human-computer interaction interface of a comm...
