基于VS1003+GUI的频谱显示 void, include

#include "GUI.h"

typedef unsigned int u16;
typedef unsigned char u8;

Msg1.MsgId=WM_PAINT;
while(1)
{
  /*这里是用随机数产生的频谱，只需要将vs1003读出的频谱数据送到SPEC数组中就可以实现频谱的显示*/
  for(i=0;i<14;i++)
  {
   SPEC[i]=rand()%100;
  }
  WM_SendMessage(hWnd,&Msg1);
     WM_Exec();
}
}

具体效果过几天试试 先发出来希望大家能分享下自己的想法
