Abstract
Design of wireless data transmission system in short distance by using FPGA and RF chip nRF2401 is introduced in this paper: The wireless data communication system constitutes of SOPC (the core of the system) embedded in FPGA and the necessary peripheral circuits. The paper also introduces the usage of the burst mode transfer of the Wireless transmission chip under the control of FPGA and the principles of wireless transmission. And the main features and usage of the wireless digital chip nRF2401 are introduced. Design of half-duplex communication in the sudden transfer mode and the key technology of wireless data transmission are also involved in the paper. The system is controlled easily, work steadily and can realize the wireless data transmission. The entire system is designed by SOPC Builder and Quartus II, the main control adopts C to programming. The design is downloaded into FPGA device which belongs to the Cyclone I family of Altera. The design is very agile, and easy to debug. The system has the advantage of simple structure, low-budget, low power consumption, etc. This makes the system applicable to outdoor environment and any other monitoring of the dynamic system state.
