Embedded Studio本身有直接导入Keil工程文件的功能，导入也很方便。但今天我们试直接创建一个用ARMCC来编译的Embedded Studio工程文件。

Embedded Studio工程文件结构

一个.emProject文件包含一个解决方案，每个解决方案可以包含多个工程和多个配置。每个工程又包含多个配置，工程中的配置是可以继承解决方案中的同名配置的。

图 1

创建一个新工程

点击 File>>New Project...，选择将工程添加到一个新的解决方案中，还是添加到当前解决方案中。我们这儿选择创建一个全新的解决方案。

图 3

选择外部编译可执行文件，设置好工程名及存储路径。点击Next后选择目标设备及调试接口以及默认创建的配置文件即可。

默认创建了一个Debug配置文件和一个隐藏的common配置。

</solution>

配置Keil编译器路径

我们刚刚创建的解决方案中，所有工程都是基于LPC1752的且都采用ARMCC进行编译。所以选择直接在解决方案中的common配置中对公共参数进行设置，这样所有工程的配置都可以继承这些配置。(导入keil工程自动生成的emProject文件是新创建了一个External Keil ARMCC的配置)

</solution>

KEIL_TOOLKIT_DIR=D:/Keil_v5/ARM就是配置本地Keil编译器路径。
注： 一定要在解决方案上右键选择Options...,在弹出的对话框中选择Common配置文件进行配置。

配置外部编译器为ARMCC

注： 必须在工程上点击右键选择Options...,并设置Debug配置中的External Compiler为ARMCC。

添加源文件

直接将源文件夹拖动至工程目录下，就可以添加目录下的所有文件。但这样拖动添加的文件夹是没有包含子目录及子目录下的文件的。可以通过以下设置自动添加子目录及子目录下的文件。

注： 一定要在文件夹上右键选择Options...

编译工程

至此已经可以通过keil的ARMCC编译工程了，但仍有一些问题。此时的编译结果如下图

图 7

只有Flash使用情况，却没有RAM使用情况。对工程的Debug配置添加如下图配置

图 8

再次新编译结果如下图
