| 摘 要： | 无线传感器网络节点需要非易失性的外部存储器来保存自身采集的数据、路由信息等传感器数据。这就需要节点上的微处理器能够访问外部存储器。在专门为传感器网络设计的微型操作系统TinyOS中,没有支持对串行EEPROM进行相关操作的底层驱动程序。根据实际需求,在分析了串行EEPROMAT24C512B的功能和TinyOS下硬件抽象体系结构的基础上,设计了基于I2C总线的EEPROM硬件抽象组件体系,实现了TinyOS下基于MSP430平台的串行EEPROM驱动程序,同时满足了应用开发的灵活性与传感器节点功耗低两方面的需求。

| Abstract: | The node of wireless sensor networks requires nonvolatile external storage to preserve the sensor data such as route information,collected data.TinyOS,the operating system which is special for wireless sensor networks,has no driver to support the operation to the serial EEPROM.Base on the actual demand,the function of AT24C512B and harware abstraction architecture of TinyOS are analyzed in details,The EEPROM harware abstraction component architecture base on I2C-BUS is designed,and the TinyOS driver of serial EEPROM for MSP430 platform is implemented.The result shows that the drive meets agility and energy-efficiency requirements of sensor network applications |
