场景很简单。我需要实现一个内存拷贝函数，类似memcpy，使用的是DMA方式拷贝，在这个函数中配置好DMA地址后就一直等待DMA中断，然后退出这个函数。在其它RTOS中可以非常简单的等待一个信号量即可，但在contiki中，完全没找到有类似信号量之类的可以直接传入到函数中的东西，貌似事件都必须传给线程，也就是说我这个memcpy必须形参要有线程这个参数？求教各路大神，我只想做一个通用的内存拷贝函数，形参不想加线程相关的东西，能做到吗？

Radio-Duty-Cycling这么好的一个东西，居然没有被IEEE收录到IEEE802.15.4中，

我刚接触contiki，我想在contiki操作系统下实现在rime协议栈下cc2530的接收功能，请问我该如何实现，有没有相关的资料例程？

现在什么东西都能联网，灯泡、恒温器、咖啡机，甚至是动物。 獾是一种长时间居于地下的动物，让动物学家和生物学家很难确定他们的行踪，GPS等技术在地下也往往不能正常工作。不过在五年前，牛津大学的研究人员Andrew Markham和Niki Trigoni发明了一种可用于地下的无线追踪系统，而这一系统是基于一个开源操作系统Contiki。 “Contiki的作用很大，它允许快速成型，也很容易在不同硬件平台上切换。”Markham表示。 Contiki不如大家熟知的Windows，OS X和Linux

Contiki RDC不是属于IEEE802.15.4的规范么？

大佬们，请问将contiki传感器AP节点插到USB上，怎么与电脑通信啊

现在可以进入休眠，但是不能唤醒。 通过查资料知道etimer可以唤醒，但是配置后就无法进入休眠了。 能给

Win32 native TI CC2530 TI CC2430 TI MSP430 STM32 Atmel AVR Freescale MC1322x LPC2103 等

RDC的本质就是持续长时间发射2.4G的信号，几乎就是连续波，这种连续波是否会干扰WIFI？

The Sensortag has an an array of built-in sensors, for which the Contiki 3.0 release adds device drivers that are ready to be used out of the box: infrared ambient temperature sensor, ambient light sensor, humidity sensor, barometric pressure sensor, a magnet sensor, and a 9-axis accelerometer and gyroscope.

Instant Contiki is an entire Contiki development environment in a single download. It is an Ubuntu Linux virtual machine that runs in VMWare player and has Contiki and all the development tools, compilers, and simulators used in Contiki development installed. Instant Contiki is so convenient that even hardcore Contiki developers use it.

Contiki is designed to operate in extremely low-power systems: systems that may need to run for years on a pair of AA batteries. To assist the development of low-power systems, Contiki provides mechanisms for estimating the system power consumption and for understanding where the power was spent.

Contiki provides a full IP network stack, with standard IP protocols such as UDP, TCP, and HTTP, in addition to the new low-power standards like 6lowpan, RPL, and CoAP. The Contiki IPv6 stack, developed by and contributed to Contiki by Cisco, is fully certified under the IPv6 Ready Logo program.

Contiki is designed for tiny systems, having only a few kilobytes of memory available. Contiki is therefore highly memory efficient and provides a set of mechanisms for memory allocation: memory block allocationmemb, a managed memory allocator mmem, as well as the standard C memory allocator

Contiki provides both community support, through the Contiki developer community, and commercial support.

Contiki is open source software: Contiki can be freely used both in commercial and non-commercial systems and the full source code is available.

Contiki is developed by a world-wide team of developers with contributions from Atmel, Cisco, ETH, Redwire LLC, SAP, Thingsquare, and many others, led by Adam Dunkels ofThingsquare.

单机模式

Contiki provides powerful low-power Internet communication. Contiki supports fully standard IPv6 and IPv4, along with the recent low-power wireless standards: 6lowpan, RPL, CoAP. With Contiki's ContikiMAC and sleepy routers, even wireless routers can be battery-operated.

Contiki只需几kilobyte的代码和几百字节的内存就能提供多任务环境和内建TCP/IP支持。

Contiki是一个专门针对物联网或者无线传感器网络应用的操作系统和协议栈，在科研以及产业化方便得到广泛的应用。在该领域，还有一个知名的类似的系统- TinyOS

Contiki is designed to run on types of hardware devices that are severely constrained in memory, power, processing power, and communication bandwidth. A typical Contiki system has memory on the order of kilobytes, a power budget on the order of milliwatts, processing speed measured in megahertz, and communication bandwidth on the order of hundreds of kilobits/second. Such systems include many types of embedded systems, and old 8-bit computers.

Contiki 是一个适用于有内存的嵌入式系统的开源的、高可移植的、支持网络的多任务操作系统。包括一个多任务核心、TCP/IP 堆栈、程序集以及低能耗的无线通讯堆栈。Contiki 采用 C 语言开发的非常小型的嵌入式操作系统，运行只需要几K的内存。
