【51汇编·STC8H】数码管显示结果与在线仿真结果不同|已解决
本帖最后由 STCAI-32位8051 于 2024-4-17 16:14 编辑为什么我在线软件仿真的结果是22271059，但是在单片机上却显示了22（反过来的6）70898
代码如下：
$INCLUDE (STC8H.INC)
ORG 0

MAIN:
LCALL GPIO
MOV R0, #50H;把片内基本RAM地址50H给R0
MOV @R0, #2
INC R0

MOV @R0, #9 ;此时R0=57H

PUSH 30H
PUSH 31H
MOV 30H,#32
MOV 31H,#39
NEXT2:

POP 31H
POP 30
RET
END
我知道了！MOV R3,#07EH 这句戳了，7F才对
