Title    Wireless transceiver based on single chip microcomputer                    
Abstract
With the progress and development of science and technology, various disciplines of mutual penetration and coverage has become an inevitable trend in the development of new technologies. Based on single-chip wireless transceiver systems have been increasingly used. Wireless transceiver system can be used in garage door control, toys, remote control, security monitoring, alarm systems, etc., with a wide range of applications in various fields. Below using AT89C51 microcontroller core, the use of wireless applications M145026/M145027 encoding and decoding chip wireless transceiver system design, the transmitter sends coded information to the receiving end, after the wireless receiver and decoded at the receiving end of the display screen, by real-time clock chip control and regulation, and can control the motor.
