很多朋友都在想，怎么让keil C51与ARM能够并存使用。

有安装经验的朋友都知道，安好C51后再安ARm，C51不能正常工作；安好ARM后再安C51，ARM不能正常工作.网上也有相关解决办法，不过不怎么样，要么不详细，要么就是复制粘贴。

不多说看图片：我想大家一定发现问题了，就是在c51的编译器等目录下面没有他的目标路径而arm有，所以他肯定会提示工具不匹配之类的问题。

解决方法很简单，根据ARM的样子也写个路径就OK了，第一：先安装C51(必须先安装C51，不能先安装ARM，否则会失败。

)第二：安装keil ARM(不能安装在同一个文件夹下)我当前安装的是mdk arm4.53第三：打开keil c51和keil arm 两个文件夹，分别找到tools.ini分别打开两个“tools.ini”,将keil C51文件夹下的tools.ini文件中[C51]段复制到keil ARM中tools.ini文件的最后；将keil ARM文件夹下的tools.ini文件中[ARM]段复制到keil C51中tools.ini文件的最后：tools.ini -->keil ARM[UV2]ORGANIZATION="小川电子工作室"NAME="小川电子工作室", "小川电子工作室"EMAIL="paulhyde@"ARMSEL=1BOOK0=UV4\RELEASE_NOTES.HTM("uVision Release Notes",GEN)[ARM]PATH="D:\Keil ARM\ARM\"VERSION=4.50PATH1="C:\Program Files\arm-none-eabi-gcc-4_6\"TOOLPREFIX=arm-none-eabi-CPUDLL0=SARM.DLL(TDRV0,TDRV5,TDRV6,TDRV10) #
