Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The invention uses the PS / 2 standard interface of the ordinary computer to encode and decode data through a self-defined communication protocol without changing the system drive, so as to realize the data communication between the computer and the special keyboard. Users can edit any custom keyboard information in the upper layer editing software to make it the data allowed by the host operating system, and download it to the Flash of the keyboard through the PS / 2 standard interface of the ordinary computer to realize the programming and editing of the keyboard key information. Online upgrade of new version programs. At the same time, the current key information of the keyboard can also be uploaded to the upper editing interface of the ordinary computer through the standard PS / 2 interface for display, thereby realizing the two-...

Abstract

The invention relates to a method for realizing programmable special keyboard, wherein the invention uses PS / 2 standard interface of common computer, without changing the driving program of system, to code and decode data via self-defined communication protocol, to realize the data communication between computer and special keyboard; and user can edit self-defined keyboard information in the upper edit software, to process it into the data allowed by host operation system, to be downloaded into the flash of keyboard via the PS / 2 standard interface, to program keyboard information and online upgrade new program; at the same time, the present key information of keyboard via PS / 2 interface can be transmitted and displayed in superior edit interface of computer to realize bidirectional interaction, and improve the reliability and stability of system communication.

Description

technical field [0001] The present invention relates to a method for realizing a programmable keyboard, in particular to a method for realizing data communication between a computer and a special keyboard through the PS / 2 standard interface of a common computer, so as to complete the programming and editing of key information on the keyboard. New version upgrades. Background technique [0002] In the commercial cash collection system, the terminal keyboard used by the salesperson is not an ordinary PC keyboard, but a special keyboard that meets the requirements of the cash collection system. This kind of keyboard should define the content of each button according to the requirements of the system software, so a programmable keyboard is needed to meet this requirement. When the host and the keyboard transmit data through the PS / 2 interface, due to the restrictions on the operating system (DOS, WINDOWS, LINUX) of the host, the data through the PS / 2 interface must be the data ...
