12864显示问题显示一幅图后再显示下一幅时间很长在显示图像之前先要写点阵

12864显示问题显示一幅图后再显示下一幅时间很长在显示图像之前先要写点阵
要是不写点阵图像会重叠用cllrom()函数也不行写点阵的时间太长了
我用的是OCMJ4*8C 显示程序如下
#include <reg52.h>

#define uintunsigned int
#define uchar unsigned char
#define x1 0x80
#define x2 0x88
#define y 0x80
#define comm0
#define dat 1

sbit cs = P0^0;
sbit std= P0^1;
sbit sclk = P0^2;
sbit psb= P0^3; //H=并口; L=串口;
sbit rst= P0^4; //Reset Signal 低电平有效

void wr_lcd (uchar dat_comm,uchar content);
void delay (uint us);

uchar code tab1[]={
"本系列中文模块内"
"任意位置反白显示"
"置二级字库，可在"
"使用更方便更灵活"
};

uchar code tab31[]={
"金鹏科技有限公司"
"Golden Palm TECH"
};
uchar code tab32[]={

你自己在程序里面写的就是先显示点阵的啊~直接清屏之后在显示图像就好了啊~12864本来就又点慢的~要不就用快点的单片机~

yinxuewang 发表于 2008-8-15 16:37:24

但如果我不让它显示点阵的话图像就出现重影了清屏也不行

REI_AYANAMI 发表于 2008-8-15 16:40:33

放一张1024字节的图片进去~显示的是空白~就是全是0X00的~显示图片1后就显示这个空白图片~再显示图片2~偶就是这样的~貌似是绘图RAM没有清干净~偶又不太清楚这么清~索性用全白的去覆盖了~

yinxuewang 发表于 2008-8-15 16:56:42

呵呵就是因为这样换屏的时间才特长呀
写一张图片和点阵时间应该是一样的

REI_AYANAMI 发表于 2008-8-15 17:01:25

那把单片机换个晶振吧~要不换个单片机~偶用5410的~1T的单片机~比51快多了~内核也是51的~用起来一模一样~

yinxuewang 发表于 2008-8-15 17:08:49

呵呵没有那个硬件呀我是穷学生一个
老师就给了个51 呵呵

yinxuewang 发表于 2008-8-15 17:10:53

而且用的是串口如果条件允许才不用费这些事呢
用并口读-改-写不就行了吗
要还是慢换个大RAM的片子呵呵

REI_AYANAMI 发表于 2008-8-15 17:16:43

5410也不贵的啊~只要10块钱够了啊~51也要个5块左右吧~不过性能好很多啊~并口的读是不是送了读指令后再读D0到D7管脚就可以了？偶没有并的读过不知道啊~串的又不会读~

r051463438 发表于 2009-3-8 18:58:31

对呀,这个重影,我也有这样的问题.

hyz_avr 发表于 2009-3-8 19:11:53

图片? 点阵?

为什么显示完一副不能直接显示下一副呢..

r051463438 发表于 2009-3-12 18:11:12

我的重影问题解决了!!!!!

原来,在写入下一幅图之前,先关了图片显示,再清屏,再写入下一幅图就行了,没有重影了.

不过我用的是带字库的12864.

我也遇到过呢
