1616LED点阵滚动显示屏

16×16LED点阵滚动显示屏

一、硬件原理图

二、汇编程序：

;多字移动

;一个字占32个字节，1K可以存放1K=1024字节/32=32个字，C51=4K=128个字，C52=8K=256个字。

;但程序占用160个字节（相当于5个字的空间），最终可以显示的字为C51=123个字，C52=251个字。

;超过后单片机将存储不下。

ORG000H

JMPMIAN

ORG030H

MIAN:

MOVP3,#00;关闭端口

MOVP1,#0FFH

MOVP0,#00

MOVP2,#00

CALLDELAY;延时1ms

MOVR5,#2;移动列的数量（列数乘2）

MOVA,#151;显示几个字

MOVB,#32;一个字=32个码

MULAB

MOV22H,A;存放1～8个字的数量

MOV23H,B;存放8的倍数个字的数量

;如50个字：

50×32=1600=0640H,则DPH处为06H=6，DPL处为40H=64

;简单算法：

50÷8=6余2，6为DPH处数，余的2×32=64为DPL数

MOVDPTR,#TABLE1;赋查表初址

MOVR0,DPL;保存DPTR初值,R0、R1记录取码进度

MOVR1,DPH

MOV20H,DPL;20H、21H保持DPTR初值不变

MOV21H,DPH

LOOP:

MOVR7,#5;每屏停留时间

L1:

MOVR6,#16;每屏16个码

MOVR4,#00;扫描指针清零

MOVDPL,R0;取码指针存入DPL

MOVDPH,R1

L16:

MOVA,R4;扫描指针存入A

MOVP1,A;扫描输出

INCR4;扫描指针加1

CLRA;A清零

MOVCA,@A+DPTR;查表送A

MOVP0,A;送P0口显示

INCDPTR;取码指针加1

CLRA;A清零

MOVCA,@A+DPTR;查表送A

MOVP2,A;送P2口显示

INCDPTR;取码指针加1

CALLDELAY;扫描延时1ms

MOVP0,#00;清除屏幕

MOVP2,#00

DJNZR6,L16;1屏是否完成?

DJNZR7,L1;每屏停留时间是否到了?

;MOVR0,DPL;如字不需移动，用该指令

;MOVR1,DPH

MOVA,R0;如字需移动，用该指令

ADDA,R5;如大于256，C=1

MOVR0,A

JNCDP

INCR1

DP:

MOVA,20H;DPL初值

ADDA,22H;如大于256，C=1。

因DPL初值在90H以上，显示4个字后DPH将加1，导致判断失误

MOVA,DPH

SUBBA,21H;已显示字的数量（乘8）

CJNEA,23H,LOOP;DPH中的字是否完成？

CLRC

MOVA,DPL

SUBBA,20H;已显示字的数量

CJNEA,22H,LOOP;DPL中的字是否完成？
