神州IV开发板的MCU型号为STM32F107VC，而官方提供的例子中STM3210C-EVAL是用的这款MCU，这点很重要，开始选用的是STM3210E-EVAL走了弯路，因为STM3210E-EVAL用的是STM32F103Z MCU，移植步骤如下：
1，复制STemWin源码包到测试工作目录，如STemWinTes等等。我的是MVC。
2，定位到E:\MVCProjects\MVCTest\STemWin_Library_V1.1.2\Project\STM3210C-EVAL\RTOS\EWARM目录，打开STemWinDemo.ww，前提是你的系统中安装了EWARM V6.3 以上开发环境。
3，Project -> Options -> General Options ->Target ，选中Device，点击右边列表按钮选中STM32F107xC，如下图。
4，选中C/C++ Complier 栏，定位到 Preprocessor页，如下图。
将如下红色部分内容复制到里面
$PROJ_DIR$\..\..\..\..\Libraries\CMSIS\Device\ST\STM32F10x\Include
$PROJ_DIR$\..\..\..\..\Libraries\CMSIS\Include
$PROJ_DIR$\..\..\..\..\Libraries\CMSIS\RTOS
$PROJ_DIR$\..\..\..\..\Libraries\STemWinLibrary522\Config
$PROJ_DIR$\..\..\..\..\Libraries\STemWinLibrary522\inc

$PROJ_DIR$\..\..\..\..\Utilities\STM32_EVAL\Common
$PROJ_DIR$\..\..\..\..\Utilities\STM32_EVAL\STM3210C_EVAL
然后同样将将下面内容复制到Defined Symbols栏
USE_STDPERIPH_DRIVER
STM32F10X_CL
顺便说下PROJ_DIR变量，它是指xxx.ww工程配置文件所在目录，这里的PROJ_DIR=E:\MVCProjects\MVCTest\STemWin_Library_V1.1.2\Project\STM3210C-EVAL\RTOS\EWARM。
切换到Assembler栏，定位到 Preprocessor页，把如下红色部分内容复制到里面
$PROJ_DIR$\..\Config
$PROJ_DIR$\..\..\..\..\Utilities\Third_Party\FreeRTOS\Source\portable\IAR\ARM_CM3
点击OK确定如上设置。
5，编译工程，如果不出意外，编译可以顺利通过。
6，打开stm3210c_eval.h文件定位到111行附近，加入下面红色部分代码
