Research and Development of Hand Held Controller Based on Wireless Radio Frequency Communication

Abstract: Based on embedded RF wireless transceiver chip,a wireless handheld controller is designed to solve the problems of routing problem, high power-consumption and great error of data transmission occurred in traditional wire handheld controllers. The new controller succeeds in decreasing the power consumption, improving the flexibility and reducing errors of data transmission. The single-chip microcomputer stm32f051c8t6 is adopted as the central processing unit, and its expansion ports are used for the design of the wireless transceiver with the module nRF905. The test results indicate that the error rate increases with the distance but it doesn’t exceed 0.02, which meet the system requirements.
