nRF2401的ShockBurst^(TM)模式及其单片机KeilC语言实现

ShockBurst^(TM) Mode of Radio Transceiver Chip nRF2401 and Its Implementation with Keil C Language

nRF2401是单片2.4 GHz的无线收发一体芯片,只需少量外围元件便可组成射频收发电路,通过SPI接口与单片机进行通信,有功耗低、内置CRC(循环冗余校验)、有可设置地址等优点。文中主要介绍其常用的ShockBurstTM收发模式以及与单片机的硬件连接实现,并介绍单片机模拟SPI接口、nRF2401的配置实现和无线收发数据的实现。单片机采用51系列W 77LE58,软件使用Keil C语言。该系统可用于点对点及点对多点的无线数据传输,传输速率最高可达到1 Mbit/s。

nRF2401 is a single-chip transceiver for 2.4GHz produced by Nordic. With a few external components, the radio-frequency transceiver circuit can be composed. It communicates via the SPI interface and one-chip microprocessor. It has such advantages as less power consumption, built-in CRC verification and software-set of addresses. This paper mainly introduces the common ShockBurst^TM transceiver mode as well as the realization of linking with the one - chip microprocessor hardware, The software part introduces one - chip microprocessor simulation interface and the realization of nRF 2 4 0 1 configuration and that of the radio transceivet data. The single-chip microprocessor employs W77LE58 of 51 series and the software uses Keil C language. This system can be used in the dot-to-dot and dot-to-dots radio data transmission and its highest transmission speed can reach 1 Mbps.
