Description: TinyOS是UC Berkeley（加州大学伯克利分校）开发的开放源代码操作系统，专为嵌入式无线传感网络设计，操作系统基于构件（component-based）的架构使得快速的更新成为可能，而这又减小了受传感网络存储器限制的代码长度。TinyOS的构件包括网络协议、分布式服务器、传感器驱动及数据识别工具。其良好的电源管理源于事件驱动执行模型，该模型也允许时序安排具有灵活性。TinyOS已被应用于多个平台和感应板中。-TinyOS is UC Berkeley (UC Berkeley) open-source operating system developed specifically for embedded wireless sensor network design, component-based operating system (component-based) architecture makes it possible to quickly update, which in turn reduced small memory limit by the sensor network code length. TinyOS components, including network protocols, distributed servers, sensor-driven and data-aware tools. Its good power management from the event-driven execution model, the model also allows for scheduling flexibility. TinyOS has been used in multiple platforms and sensor board.

Description: TinyOS系统以其组件结构模型、事件驱动、并发型等优点成为目前最受关注的无线传感器网络操作系统。而STM32和CC2520以其高性能、低成本、低功耗被广泛应用于无线传感器网络嵌入式系统。 但TinyOS 不支持STM32和CC2520芯片。因此在分析TinyOS 基本原理、NesC 编程语言实现机制及其编译过程的基础上，介绍了基于STM32和CC2520的T inyOS移植方法，完成了STM32的IO组件、Timer 组件、USART组件、SPI 组件和CC2520芯片的移植。在实现CC2520的基本通信功能基础上，实现简单mac协议。最后测试了各组件的移植效果，实验测试结果表明，节点可以稳定可靠通信。-TinyOS system, its component structure model, event-driven, and hair, etc. become the most talked about wireless sensor network operating system. STM32 and CC2520 is widely used for its high-performance, low-cost, low-power wireless sensor network embedded systems. TinyOS support the STM32 and CC2520 chip. Therefore, on the basis of the mechanism for its compilation process analysis TinyOS basic principle, NesC programming language, introduced a complete STM32 IO components Timer component, USART components, SPI group based the STM32 and CC2520 T inyOS transplant method pieces and CC2520 chip transplant. On the basis of the basic communication functions to achieve the CC2520 realize simple mac Agreement. The effect of transplantation of the various components of the final test, the experimental test results indicate that the node can reliable communication.
