Keyboard having extended keys and method for setting code of extended key

Abstract

It is a keyboard with expansion key and its set expansion key output key code method, which is to set a set key and multiple expansion keys on the keyboard. There are keyboard controller and a memory inside the keyboard, wherein, the keyboard controller is used to control the keyboard operations and the memory is to store the key codes of expansion keys. The set key is used to activate key set program of the expansion key and it uses key press to input character bunch through designed expansion key and store the character bunch in a memory as key code of the expansion key. The key code content of the expansion key is self set according to the needs and makes the expansion have multiple functions.

Description

technical field [0001] The invention relates to a keyboard with extended keys and a method for setting the output key codes of the extended keys, in particular to a keyboard which can be set by the user to output key codes. Background technique [0002] The keyboard can be said to be one of the most important input tools in the computer peripheral equipment. There are different keys on the keyboard for pressing, so the user only needs to press the keys on the keyboard to issue operation instructions, and the computer host can follow the received operation instructions. The instruction is executed. When the key on the keyboard is pressed, the key code will be output by the keyboard to the computer host, and the computer host will recognize the key and execute its corresponding function by the received key code. [0003] The standard keyboard used by general computers is mainly based on a set of coding standards established by the American Standard Code for Information Interc...

Problems solved by technology

[0006] From the point of view of the keyboard, the keys of the above-mentioned standard keyboard or additionally added expansion keys, the key codes output by pressing the keys are fixed and cannot be changed. Especially for the expansion keys, if the user wants to change the function of the expansion keys , it can only be modified by the application program on the computer system side, but this method can only be executed for the computer system that has the executable extended function key application program installed, and cannot be applied to other computers that have not installed the executable extended function key application program system

[0007] When existing keyboards are equipped with extension keys, it is impossible for users to directly change the key codes output by the extension keys, so that users can define the functions of the extension keys by themselves.
