Microsoft’s.NET MicroFramework初接觸

   花了三個小時,把Microsoft’s.NET MicroFramework的  Product Positioning and Technology Whitepaper看玩了.前面的本文,是每句話都認真的看了,當然有寫地方沒有看懂(即使寫成漢語,可能還是一樣的理解深度:對os和移動開發的知識背景不是很豐富),後面的appendix A, appendix B只看了標題.

   把前面的overview摘錄如下:
   Introduction
   For years, Microsoft has had two offerings in the embedded space: XP Embedded and Windows CE. These operating systems have formed the platform for many successful devices, such as PDAs, Smart Phones, automatic teller machines, and network switching equipment. Microsoft introduced the .NET Framework, which brings the power and reliability of managed code to scale from large servers to embedded devices. However, many devices are still too small/resource constrained to support these platforms. To serve the market for  even smaller devices, Microsoft has developed a new platform Microsoft .NET Micro Framework. (.NET MF). The .NET Micro Framework addresses this untapped area by providing a small, efficient implementation of the .NET runtime for smaller devices. This has great advantages to developers who can maintain the same managed code, use the same world class tools, and continue to participate in the world’s largest developer community. 

    面列出自己感興趣的地方(也包括從這篇文檔裡所學到的一些應該有的弱弱的常識):
   1.Microsoft’s continuum of processing capabilities for embedded applications
   Windows XPe (potentially with the .NET Framework) 
   Windows CE (potentially with the .NET Compact Framework)
   .NET Micro Framework(bootable runtime)
   2. :bootable
   The MicroFramework provides a subset of full OS features, so it does not require an OS and is referred to as a ‘bootable’ runtime
   .net mf不要求底層os的支援,這對嵌入式開發是一個很大的福音:可以在微型裝置上開發完全自主的控制器.是不是可以取代彙編和c/c++呢?!如果可以用.net做弱電開發,進行智能控制,那是多麼令人興奮的機遇呀!
   3 system requirements
  Currently the platform runs on several ARM 7 and ARM 9 processors. The suggested minimal memory configurations at present are 300K RAM and 1 Meg of Flash. The devices also need to have serial or USB support to support downloading and debugging the applications during development.
   而wince 需要12M ram,這裡只要300K,一般的小型裝置可以很容易滿足這個要求了
   4 Visual Studio Integration
   This integration supports full emulation of your device on the PC, building and deploying the assemblies to the device, and debugging the code running on the device through USB or serial connections
