啥都不说了，直接上代码，注释相当详细了。

这个一个LED流水灯的STM32工程，包含STM32库v3.5.0版本，[下载地址][Link 1]  
再详细说一下注释中没有的可能有疑问的地方：

# 要链接的静态库
    #LDLIBS += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libc.a
    #LDLIBS += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libg.a
    #LDLIBS += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libm.a
    #LDLIBS += /Users/ch-yanghl/gcc-arm-none-eabi/lib/gcc/arm-none-eabi/5.4.1/libgcc.a
    #LDLIBS += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libnosys.a

\-这一块为什么要注释：因为文中使用了

# 设置ld链接脚本文件
    LDSCRIPT    := $(SCRIPT_DIR)/stm32_flash.ld

/*stm32_flash.ld文件中最后部分内容*/
    /DISCARD/ :
      {
        libc.a ( * )
        libm.a ( * )
        libg.a ( * )
        libgcc.a ( * )
      }

这个ld脚本文件，该文件中已经包含了这些库。
