ccs3.3如何在一个工程中创建cmd文件

1、要在Memory Section Manager属性中为“Segment For DSP/BIOS Objects” 和 “Segment For malloc()/free()”分配Dynamic Memory Heaps，必须首先在要分配的段（比如，IRAM）中勾选“create a heap in this memory“，并给出heaps size。

2、要把*.tcf文件生成的*.cmd文件手动加入工程中，否则编译报错如下：

------------------------------ test.pjt - Debug ------------------------------

warning 的原因是对应行的元素没有声明。

解决办法就是加入声明。

举例如下：

#include <std.h>

#include <string.h>

//#include <stdio.h> //打开该句就可以了

void main(void)

{

unsigned int i

unsigned int sum=0

for(i = 0i<=100i++ )

{

sum += i

}

printf("the sum = %d .\n",sum)

printf("the program run over!\n")

printf("the program run over!\n")

针对每一个系列的DSP，TI官方网站上都有相应的头文件和cmd文件，你可以去TI的官网上搜索，搜索器件型号比如TMS320F2812或者关键字C/C++ Header Files，可以下载的。下载以后，解压到你想要的位置，就可以通过添加文件的方法添加了。

TI提供的头文件和cmd文件很详细，具体，基本上就够用了，当然cmd文件有时候还是要自己配置的，但是对于新手入门来说，TI提供的cmd文件已经够用了。等到你熟悉cmd文件格式和要求，就可以自己写了，这方面的资料TI官网上也有。
