用汇编语言编程 51单片机片内RAM的汇编汇编传奇充值 源码50H和60H两单元存储数若相同70H单元中存1否则存零 紧急!各位帮帮忙啊
我原来的源码mpvue 源码分析写法:用subb
MOV a,h
CLR c
SUBB a,h
JZ YES //a为0跳到YES
MOV h,#h //不相同
JMP OVER
YES:
MOV h,#h //相同
OVER:
///////////////////////================
上面这位兄台用CJNE是不是忘了加个jmp over
MOV A,H
CJNE A,H,MARK
JMP OVER //对上所改
MOV H,#H
MARK:
MOV H,#H
OVER: //对上所改
否则不管如何都会执行 在h里存0了
