我觉得是代码初始化的问题吧，按道理来说，程序执行一开始先初始化一下数码管，比如什么都不显示，或者其他

使用共阳极数码管，代码初始化中P0=0xff，同样会出现数码管G段和DP段显示，同时在软件调试模式下，从0到1变化的1000ms内，数码管动态显示全部显示数字8.，我觉得是中断显示时无法调用main函数里的数字显示语句，这里我也没找到原因，应该是调用的问题，例如当数字开始是0的时候，ledbur【0】=0%10，但是这个取余显示8.这个乱码

unsigned char ledbuf[]=
{0xff,0xff,0xff,0xff,0xff,0xff}; 改为 unsigned char ledbuf[]= {0x3f,0x3f,0x3f,0x3f,0x3f,0x3f}; |
