① 如何使用ccs7.1打开现有工程
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：

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 = 0; i<=100; i++ )
{
sum += i;
}
printf("the sum = %d .\n",sum);
printf("the program run over!\n");
printf("the program run over!\n");
② 哪位大虾知道CCS软件怎么使用啊，
一般没什么大用，除非你经常使用中文域名访问网络
17 是DNS，不可以删除，网络地址解析都靠它了，你删除也没用，它会自己回来
20 这个看不太明白，从名字上来看有点像Norton的东西，但是目录很显然不对，应该是属于危险的对象啊。可以删除试试，如果真是Norton的程序的话，可以在软件里面恢复过来
③ CCS PIC编译器的使用和安装方法
c程序设计又支持c++，当你的源程序的文件后缀采用.c时，ccs用c编译器编译
④ 关于ccs的使用
wa 忒专业了 爱莫能助了
⑤ 怎么使用ccs代码
哥们，你所谓的CCS是什么？我承认我不知道，但是我知道CSS
⑥ Ccs5.5如何链接外部文件
一共有四个步骤。
Ccs使用方法如下：
一，内联样式也叫行内样式，指的是直接在style属性中添加css。
二嵌入样式，指的是在HTML中的style标签中书写css代码。
三、是链接方式，指的是在HTML引入外部的css文件。
四是导入样式，指的是使用css规则，引入外部的css文件。
