Problems solved by technology

[0004] The expansion method of the above-mentioned common extension code is used for some hot keys or some standard keys, but cannot expand to all keyboards (such as: the text typing area on the keyboard), and the current keyboard extension codes are all fixed , cannot be set or canceled arbitrarily, for temporary application
[0005] Therefore, the above-mentioned known extension code expansion method obviously has inconvenience and lack in actual use, and it can be improved.

Embodiment Construction

[0044] see figure 1 The present invention is applied to the external appearance diagram of computer keyboard, for the convenience of the following description, the original key code (before the unprogrammed keyboard extension code) of computer keyboard 1 is called the first key code, and the key after the programmed keyboard extension code The code is called the second key code, and the first key code is the standard code of the text typing key area on the computer keyboard 1, or the extension code of the IBM special key area, wherein the computer keyboard 1 is additionally provided with a code sending mode key 11 and a viewing button 12, the code sending mode button 11 is used to switch the standard code mode and the code sending mode of the extended code mode of the relevant designated buttons, that is, by switching the code sending mode button 11, it can be determined whether the button will be changed by the standard code mode Send the first key code, or send the second ke...

Abstract

A method and its controller for the extension code of programmable keyboard is disclosed. The user can define the extension code processing instruction according to the extension code of the key to be set up or deleted. The computer system sends an instruction and a key position list to the keyboard. The keyboard can update the extension coee of the side key and uses a coe transmission mode key to switch between the standard code mode and the extension code mode.

Description

technical field [0001] The present invention relates to a keyboard function expansion method and control device, in particular to a programmable keyboard extension code method and its control device, so that all keys on the keyboard can be set or cancel the function of the extension code by the computer system, And make this key extension code can have both permanent and temporary application. Background technique [0002] The standard keyboard used by general computers is a set of coding standards formulated according to the American Standard Code for Information Interchange (ASCII) and the computer character encoding standard (ISO646), that is, 7 bits can provide 128 coding positions, which are divided into 94 respectively. There are 3 graphic character codes and 34 control character codes. After deducting the maximum number of buttons used in various languages ​​and system commands, there are not many remaining code positions that can be used. In this way, the expansion o...
