摘要
基于IEEE802．15．4无线微控制器,为在2．4G频带上应用IEEE802．15．4标准及ZIGBEE网络的开发应用提供了完整的解决方案;该芯片完全按照IEEE802．15．4标准开发,自带的附加处理器远远扩大了芯片的应用范围,使之不仅可用于短距离无线网的构建,更适用于远距离控制,家庭及建筑自动化系统;文中介绍了基于IEEES02．15．4标准的无线微控制器JN5121的SPI总线设计,给出了JN5121 SPI总线的特点、配置方式及相关函数;最后通过程序及波形图演示了主机发送数据的过程。
The JNS121 IEEE802. 15. 4 wireless mieroeontroller provides a fully integrated solution for applications using the IEEE802. 15. 4 standard in the 2. 4 -- 2. 5GHz ISM frequency band, including ZigBee. It includes all the functionality required to meet the IEEE802. 15. 4 specification and has additional processor capability to run a wide range of applications including but not limited to Remote Control, Home and Building Automation. This article introduced the design method of JNS121 serial Peripheral Interface, presented its features , the way of configuration and the functions. Finally, we illustrated the processing of transaction by the programming and waveforms.
