  }
  if (j == 4)

  else if (i == 4)
Pad_1 = 1;
}
int Get_Pad1()
{
  return Pad_1;
}
__interrupt void BT_ISR(void)
{
  int i;
  for (i=0;i<800;i++);
TouchPad_Scan_Pad1();
  __low_power_mode_off_on_exit();

}
这个是Touch.c的程序。
下面是主程序的主循环部分：
  while(1)
{
      delay_0(50);
      if (Get_Pad1())
      {
         m++ ;
         if (m == 0)
         Disp1Char(12,0,'0');
         if (m == 1)
         Disp1Char(12,0,'1');
         if (m == 2)
         Disp1Char(12,0,'2');
         if (m == 3)
         Disp1Char(12,0,'3');
         if (m == 4)
         Disp1Char(12,0,'4');
         if (m == 5)
         Disp1Char(12,0,'5');
         if (m == 6)
         Disp1Char(12,0,'6');
         Delay5ms();
      }
      else
         Disp1Char(12,0,'8');
}
