Research and design of wireless transmission system based on nRF905

In this paper, LPC2200 Series processors and wireless transceiver module nRF905 are used to build the wireless network transmission system hardware platform. The hardware interface and equipment performance of LPC2200 processor and nRF905 are introduced and the design is proposed. The architecture of hardware circuit between embedded processor and wireless module is given, the processor I / O pins control procedures is designed, SPI bus data transfer function, driver of nRF905 and wireless data transmission function are programmed. This paper uses RFID technology to achieve a low rate of data transmission functions. This paper provides some reference for continue in-depth studying on wireless networks and realizing data communications in short distance.
