 按需要生成工程文件:
-1. 修改 rtconfig.py :
-CROSS_TOOL='keil'           #使用的工具链
+1. 修改当前文件夹内 rtconfig.py :
+CROSS_TOOL='keil'           #使用的工具链.
 STM32_TYPE = 'STM32F10X_HD' #STM32对应的型号.
-2. 修改 rtconfig.h 配置需要的功能.
-2. 执行 scons --target=mdk  生成MDK工程文件.
+EXEC_PATH 	= 'C:/Keil' #Keil安装路径.
+IAR_PATH 	= 'C:/Program Files/IAR Systems/Embedded Workbench 6.0 Evaluation' #IAR安装路径.
+2. 修改当前文件夹内 rtconfig.h 配置需要的功能.
+3. MDK：在当前文件夹内执行 scons --target=mdk  或 scons --target=mdk4 生成MDK 4工程文件 project.uvproj
+        或在当前文件夹内执行 scons --target=mdk5 生成MDK 5工程文件 project.uvprojx
+   IAR：在当前文件夹内执行 scons --target=iar 生成IAR工程 project.eww.
+4. 将bsp\stm32f10x\drivers内board.h中STM32_SRAM_SIZE的值修改为与芯片SRAM大小一致.
 
-note: 需要安装 python,scons.
+note: 需要安装 python 2.7,scons.

+Generate project files as needed:
+1. Modify the files in the current folder:
+CROSS_TOOL='keil'           #The tool chain in use.
+STM32_TYPE = 'STM32F10X_HD' #The type of stm32.
+EXEC_PATH 	= 'C:/Keil' #The installation path of the Keil.
+IAR_PATH 	= 'C:/Program Files/IAR Systems/Embedded Workbench 6.0 Evaluation' #The installation path of the IAR.
+2. Configure the required functionality by modifying rtconfig.h in the current folder.
+3. MDK:Execute the scons --target=mdk or scons --target=mdk4 in the current folder to generate the MDK4 project project.uvproj.
+       Or execute the scons --target=mdk5 in the current folder to generate the MDK5 project project.uvprojx.
+   IAR:Execute the scons --target=iar in the current folder to generate the IAR project project.eww.
+4. Change the value of STM32_SRAM_SIZE in board.h(bsp\stm32f10x\drivers) to match the chip SRAM size.
+
+note:Need to install python 2.7 and scons.
