求用汇编语言编一个很简单的程序。。。

TIMES EQU 40H ;循环次数
COL EQU 41H ;决定扫描哪一列
NUM EQU 42H ;决定列显示代码
ORG 0000H
LJMP MAIN
ORG 0030H
MAIN: MOV TIMES,#00H
MOV COL,#00H
MOV NUM,#00H
LOOP: MOV P3,#00H ;在下一次显示之前清除原有显示代码
MOV DPTR,#TAB0
MOV A,NUM
MOV B,#8
MUL AB
ADD A,COL
ADD A,#8H ;考虑到表中第一行为列显示代码
MOVC A,@A+DPTR
CPL A
MOV P1,A ;列显示代码
MOV A,COL
MOVC A,@A+DPTR ;取代码
MOV P3,A ;决定哪一列显示
CALL DELAY
INC COL
MOV A,COL
CJNE A,#8,LOOP ;判断是否扫完8列
MOV COL,#00H
INC TIMES
MOV A,TIMES
CJNE A,#200,LOOP
MOV TIMES,#00H
INC NUM
MOV COL,#00H
MOV A,NUM
CJNE A,#10H,LOOP ;判断是否扫描完0~F
MOV NUM,#00H
LJMP LOOP
DELAY: MOV R5,#01
D2: MOV R6,#01
D1: MOV R7,#248
DJNZ R7,$
DJNZ R6,D1
DJNZ R5,D2
RET
TAB0: DB 001H,002H,004H,008H,010H,020H,040H,080H ;从第1列到第8列的列扫描码

汗 一楼 你让我很纠结
话说 在8*8的矩阵画一个6不久就完了么 有那么纠结了
就是有点麻烦而已

这个要取模，还要涉及硬件的连接
