Abstract

The invention discloses a key code transmitting method for a key-free keyboard device. The key code transmitting method for the key-free keyboard device comprises the following steps: the key-free keyboard device and a computer judge the connection state between the key-free keyboard device and the computer according to the length of declaration time; the key-free keyboard device judges the type of an operation system of the computer according to the declaration numerical value. The key-free keyboard device, by transmitting the respective key code of number lock or caps lock, or the transmitting time and the response time generated by the key codes of the number lock and the caps lock, obtains the performance parameter of the computer.

Description

technical field [0001] The invention belongs to an electronic digital data processing technology, in particular to an input technology for converting data to be processed into a form that can be processed by a computer. Background technique [0002] The computer has become the most indispensable partner of human beings in the 21st century. In order to facilitate the operation of the computer by users, various human-machine interface devices have sprung up, and in order to make the transmission between the computer and the keyboard faster, A Universal Serial Bus (USB) with hot-swappable and plug-and-play features has been developed to serve as a communication bridge between a computer and a keyboard, and it is referred to as a USB keyboard for short. [0003] Traditional USB keyboards have more than 104 keys. Although the keys can be integrated with functions, the more functional keys do not bring convenience to the user, and the complex functions make the user dazzled and ca...
