Wireless keyboard is no direct physical connection between the keyboard disk and the computer, and the input information is transmitted to a special receiver through infrared or radio waves. Bluetooth devices, to be precise. The so-called Bluetooth technology, in fact, is a short-range radio technology, using. Bluetooth " Technology that can effectively simplify the communication between mobile communication terminal devices such as PDAs, laptops and mobile phones.
The first: the simplest way is to remove the circuit of another wireless keyboard, using the matrix keys of the original keyboard to modify, only need to do matrix analysis and hardware modification on the line;
two
The second is to use the single chip computer to read the signal of the original keyboard and then forward it to the receiver of the computer through the 2.4G wireless module or Bluetooth module, and then the single chip computer at the receiving end decodes the signal to the computer;
three
The third way to analyze the communication protocol between the keyboard and the computer, completely use the single chip microcomputer to achieve wireless codec and communication, programming is the most complex, but these work program providers basically have a ready-made side
1, can be changed to the transmitter or can not get out of the line keyboard needs to plug into the transmitter to power the transmitter, which is no different from the cable.
2, the amount of engineering to change the lithium battery with charging signal is too large.
3, not practical you use machinery must be in order to play the game to play the game with wireless delay is high
