ABSTRACT:
A multifunctional universal serial bus (USB) wireless keyboard for operating a control function of a personal computer (PC) is presented. A main body of the keyboard includes a plurality of keys, a signal sending module, and a coding circuit. When the key is pressed, the coding circuit generates a corresponding character signal, and the signal sending module converts the character signal into a radio signal and sends the radio signal. A receiving module receives the radio signal, and transmits the radio signal to the PC. The receiving module further includes a clock control pin and a USB module electrically connected to the PC. An embedded controller is disposed in the PC and electrically connected to the receiving module through the clock control pin, and sends a corresponding function trigger signal to a south bridge chip set according to a pressing time of the received radio signal.
