摘要
nRF24LE1是2.4 GHz ISM微波频段的低成本、高性能嵌入式微处理器智能射频收发器家族中的成员.设计了基于射频收发芯片nRF24LE1的无线数据传输系统,给出了射频收发系统主要部分的硬件电路图和软件收发程序流程图,重点探究了nRF24LE1在Enhanced ShockBurstTM收发模式下的无线数据收发过程和实现.室外测试实现了50 m以上的远距离无线数据传输,具有功耗低、传输距离远及性能稳定等优点,可广泛应用于多种无线数据传输的场合.
nRF24LE1 is one of the embedded microprocessor-based smart RF transceiver family members with low-cost and high-performance in 2. 4GHz ISM band microwave section. The wireless data transmission system based on RF transceiver chip nRF24LE1 is designed in this paper. The hardware circuit diagram and sending and receiving program flow in this system are given. The process of wireless data sending and receiving for nRF24LE1 under ShockBurstTM mode are researched emphatically. In practical test, wireless data transmission beyond 50m long- distance is successfully carried out. This system with low power consumption, long transmission distance and stable performance can be widely used in various fields of wireless data transmission
