摘要
nrf9E5是真正的系统级无线射频收发芯片,内嵌高性能的8051MCU和无线收发芯片nRF905,nrf9E5将所有高速射频协议集成在芯片内部,与微控制器相连的部分只是简单的SPI口。本文介绍了基于nrf9E5数据采集模块的功能和设计方法,并对怎样利用TDMA防止数据碰撞实现的点到多点通信进行了详细讨论,此系统具有测点多、便于扩展、抗干扰性强等优点。
nRF9E5 is a true single chip system with fully integrated RF transceiver, 8051 compatible microcontroller and nRF905 transceiver. By embedding all high speed signal processing related to RF protocol in the transceiver, the nRF905 offers the microcontroller a simple SPI interface. This paper introduces the function and design of taking data acquisition and control module based on nRF905, How to realize point and multi-point between communication make use of the TDMA prevent from data collision is discussed in detail. It has many advantages such as abundant measuring points , easy to expand , and high interference immunity.
