MIA EQU 30H
MIAO EQU 31H
FEN EQU 32H
SHI EQU 33H
ORG 0000H
SJMP START
ORG 000BH
LJMP TTT
ORG 0010H
START:MOV SP,#60H
MOV MIAO,#0
MOV MIA,#20 ；定时20次即20*50ms=1s
MOV FEN,#0
MOV SHI,#12
MOV TMOD,#01H
MOV TL0,#0B0H
MOV TH0,#3CH
SETB ET0
SETB TR0
SETB EA ；启动50ms定时器
LOOP:LCALL MIAOS 秒到60分加1且秒复位，分、时同秒算法
LCALL MIAOX 我采用动态显示，p1时数码管选线，p0是数码管字形

兄的，按键部分你就自己来吧！注意按键去抖动！
程序我已试过可行！看你给的分挺高的！
