127, 111, 119, 124, 57, 94, 121, 113
}; // 0,1,2,....9, a, b, c, d, e,f

//毫秒定时中断函数
static void handle_Timer0_interrupts(void)
{
IOWR_ALTERA_AVALON_TIMER_STATUS(TIMER_BASE,0);//清 TO 标志
if(flag < 1000) flag = flag+1;
else
{ flag = 0; second++;
if(second==60) second=0; }
}
//主函数
int main (void)
{ flag = 0; second = 0;
