我搞了二天了還是沒法子讓定時器動作...真的不懂...大大們幫個忙 #include unsigned int num=0; unsigned char lp=0; code unsigned char table[]= {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f, 0x77,0x7c,0x39,0x5e,0x79,0x71}; void main() { P2=0; P1=P1&0xf8; TMOD=0x11; EA=1; ET1=1; TR1=1; TH1=(65536-49995)>>8; TL1=(65536-49995)&0xff; TR1=1; while(TF0==0) { TF0=0; TH1=(65536-49995)>>8; TL1=(65536-49995)&0xff; { num++; if (num==30) { num=0; if (lp==16) { lp=0; } P2=table[lp]; lp++; } } } }

定时器就是确定工作方式给初值开中断写中断函数就可以了啊
