图是ARM的显示。暂时还未能去除TTF大字锯齿，应该要换成图片字体才行。

真正的TTF字体，多大的字都不再有那种毛刺

命令行程序再修改成这样

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<time.h>
#include<math.h>

#include<windows.h> //Sleep()

void main(){
double sec;
int days, hh, mm, ss;
struct tm * tmEnd;
time_t tNow,  tEnd;

//tmEnd initializing
// tmEnd=localtime(&tNow);
tmEnd = malloc(sizeof(struct tm)+1);
memset(tmEnd, 0, sizeof(struct tm) );

tmEnd->tm_year=122;tmEnd->tm_mon=5;tmEnd->tm_mday=26; tmEnd->tm_yday=0;
tmEnd->tm_hour=0;  tmEnd->tm_min=0;tmEnd->tm_sec=0;
tEnd=mktime(tmEnd);
system("title CountDown");
while(1){
      time(&tNow);
      sec=tEnd-tNow;
      days=sec/86400;
      sec=sec-days*86400; hh = sec/3600;
      sec=sec-hh*3600; mm = sec/60;
      sec=sec-mm*60;    ss = sec;
      printf("\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b%d-%02d-%02d -> %ldD%02d:%02d:%02d",
            tmEnd->tm_year+1900,tmEnd->tm_mon+1,tmEnd->tm_mday, days, hh, mm, ss);
      Sleep(998);
      if(days==0 && hh==0 && mm==0 && ss==0)break;
}
printf("\r\n");
