Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] figure 1 It is a flowchart of a dynamic keyboard matrix function switching method in one embodiment. The dynamic keyboard matrix function switching method includes the following steps:

[0036] Step 102, acquire the keyboard matrix type.

[0037] Specifically, the keyboard matrix type can be defined in various types according to functional requirements. For example, the keyboard matrix can be defined as an 8×16 or 8×18 matrix, or a keyboard matrix with fewer keys can be defined, which is not limited here. After the keyboard matrix type is defined, the meaning of each key can be defined ac...

Abstract

The present invention relates to a dynamic keyboard matrix function switching method and system. The method comprises the following steps: acquiring a keyboard matrix type; and obtaining a corresponding keyboard scan code from a keyboard matrix type and keyboard scan code correspondence table pre-stored in embedded controller codes according to the keyboard matrix type. According to the dynamic keyboard matrix function switching method and system, by identifying the keyboard matrix type, the corresponding keyboard scan code is obtained from the pre-stored keyboard matrix type and keyboard scan code correspondence table for use, so that a set of embedded controller codes are adaptive to a plurality of types of keyboards, the number of the embedded controller codes is reduced, and maintenance difficulty of the embedded controller codes is reduced; and another set of embedded controller codes do not need to be refreshed for changing a keyboard when demands are different, so that work load of repeatedly refreshing the embedded controller codes is reduced, and the probability of errors caused by repeatedly refreshing the embedded controller codes is reduced.

Description

technical field [0001] The invention relates to computer auxiliary equipment, in particular to a dynamic keyboard matrix function switching method and system. Background technique [0002] As computers are widely used in industrial control occasions and various intelligent control fields, EC (Embedded Controller, embedded controller), as an important part of the computer, is playing an increasingly important role. At present, in many industrial control fields, EC chips no longer only have traditional functions such as computer auxiliary booting. As an independent control chip, the functions of EC chips make up for the shortage of computers, such as industrial signal indication, temperature alarm, and Use of special keyboards. As a special keyboard, different industrial control fields have different requirements for the keyboard matrix, so EC is required to define different Scantables (keyboard scan codes). [0003] For a traditional keyboard, a set of EC codes includes a p...
