新手学习CCS V5.4，在ccs里面调试信号调制解调程序
下面的这个程序是从网上找的：
调幅： 程序1： /*头文件定义*/ #include <type.h> #include <board.h> #include <codec.h> #include <mcbsp54.h> #include <tms320.h> #include <dsplib.h> #include <math.h> /*延迟子程序定义*/ void delay(s16 period);
#pragma DATA_SECTION(delaybuff,"delay");
short delaybuff[16]={0};
short *delayptr = &(delaybuff[0]);
short inp_buffer[1]; short out_buffer[1];
short *inp_ptr=inp_buffer; short *out_ptr=out_buffer;
HANDLE hHandset; s16 data; s16 temp_buffer[256]; /*利用查表法产生载波信号定义*/

在CCS V5.4环境下编译，就跳出来很多错误，比如 这些头文件是CCS里面自带的吗？ 怎么解决，求大侠指点！！！ |
