【Abstract】In order to facilitate the use of a PPT电子签名设备， a PPT wireless pager was designed. The system was divided into two modules， The system is divided into two modules： transmitting circuit and receiving circuit， Each module contains a STC8952 MCU and Bluetooth module带芯人孔，管桩 The transmitting circuit also comprises a mouse encoder and a D trigger to form the phase detector circuit， When the button of the transmitting circuit is pressed or the rolling wheel is rolled， the data will be sent by the Bluetooth host， after receiving the instruction， the receiving circuit send it to the PC through the USB communication module， finally the pc simulate the keyboard and the roll event， to achieve the controlling of the PPT.
