摘要
为了实现无线数据的采集,提出了一种基于nRF903模块的无线通信解决方案。讨论了无线收发芯片nRF903的用户接口功能及其配置,论述了利用过采样和UART两种方法实现无线数据传递的通信协议及其应注意的问题,给出了软硬件设计方法。利用无线通信模块实现无线数据采集系统中嵌入式主机和传感器节点之间的数据传输。
A wireless communication solution is presented to implement a wireless data acquisition system.The user interface functions of nRF903 and its configuration are discussed in this paper.The wireless communication protocol and related problems of oversampling and using UART are stated in detail.The method of software and hardware design is also presented.Data transmission between embedded host and sensor nodes is implemented by using the wireless communication module.
