Windows CE Features: � Bluetooth � TCP/IP stack und WinSock 2.0 � RAS server � remote desktop protocol (RDP) to terminal server � UPnP device host und control point � secure socket layer (SSL) � Direct3D, DVD, Direct Music APIs � Internet Explorer 5.5 for CE + free Web Server � supported CPU families: ARM, StrongARM, XScale MIPS (PowerPC support discontinued) Hitachi x86 Embedded PC 9
General advantages of Windows CE � Win32 API � 32 bit multiprocessing + multithreading � protected processes � 256 thread priorities (cmp. NT = 15 priorities, TwinCAT = 64 priorities) � small resource footprint, smallest CE fits in 200 kb ROM/Flash � genuine real-time capability starting with version 3.0 � InstantOn capable e.g. X86 boot in approx. 10 s � Embedded Visual Studio development tools � C++ Compiler � Visual Basic � multitude of processors supported � most of the OS source code is disclosed to user � low license costs Embedded PC 10
Restrictions of Windows CE � maximum 32 processes, but virtually unlimited threads � maximum 32 MB address space per process � not binary compatible to desktop Windows (W9x, WNT, W2K, WXP) � � � � desktop software will generally not function on a CE device � driver support for PC hardware is not so good � applications can run in full screen mode only � no MDI applications possible Embedded PC 11
Development tools for Windows CE Microsoft � Visual Studio.Net compiles all languages like C++, C#, VB to managed code (MSIL) � Embedded Visual C++ 4.0 � cross-compiler for all “CE”-CPUs � development environment runs on WNT, W2K, WXP (is almost identical to Visual Studio for desktop) � entire tool-suite can be downloaded for free from the Microsoft Website Third party � runtimes for several SCADA packages � NS-Basic, interpreter � pocket C, command line compiler Embedded PC 12
