此程序有错,求高手完善。
/*这个程序的要求是要用的I IC总线,然后动态显示98-255*/ 此程序有错,数码管显示从0知道25然后再回到0,同时只显示前两个数码管。请高手完善

发帖时要把你的问题说清楚,哪里出错
菜鸟,这程序运行产生什么结果,你感觉在什么地方出错,你是不是该把问题说清楚呢
已经把问题写上去了,尽管你是高级工程师,请放尊重点,你也是从初学者过来的。
不好意思,已经说明了,如果还不清楚,可以再提醒我。谢谢了。
temp=_crol_(temp1,2);
这个是哪来的,用来干嘛的
ge=x%10;
这一步似乎也有错
void timer0() interrupt 1
{
uint t;
TH0=(65536-10000)/256;
TL0=(65536-10000)%256;
if(t==1)
t=0;
t++;
TR0=0;
}
这个中断只进入一次就不再进入了,希望你能把整个程序的执行过程简要的说明一下,否则光看程序不好查出错误
这是左移2位的意思!

这个程序是24c02的程序,有IIc总线,0-99循环,时间1S,希望对你有用
谢谢。
问题不清楚啊,麻烦说清楚一点
