24、12864 的驱动程序心里特高兴就拿出来与大家希望对像我一样初学点阵 LCD 编程的有些帮助。前些天我从网上了一个程式就是用不了把我给急苦了后来我仔细看了看点阵 LCD 说明书重新写了程式这才 OK了。看来初学者也不能从网上直接程式用还要看看程式对不对头; 1.12864-1,12864-2 接口说明表管脚号 管脚 电平 说明1 VSS 0V 逻辑电源地。2 VDD 5.0V 逻辑电源正。3 V0 LCD 驱动电压，应用时在 VEE 与 V0 之间加一 2K 可调电阻。4 D/I H/L 数据指令选择：数据 D0-D7 将送入显示 RAM；低电平：数据 D0-D7 将送入指令寄存器执行。5 R

25、/W H/L 读写选择：读数据；低电平：写数据。6 E H.H/L 读写使能，有效，下降沿锁定数据。7 DB0 H/L 数据输入输出引脚。8 DB1 H/L 数据输入输出引脚。9 DB2 H/L 数据输入输出引脚。10 DB3 H/L 数据输入输出引脚。11 DB4 H/L 数据输入输出引脚。12 DB5 H/L 数据输入输出引脚。13 DB6 H/L 数据输入输出引脚。14 DB7 H/L 数据输入输出引脚。15 CS1 H/L 片选择信号，低电平时选择前 64 列。16 CS2 H 片选择信号，低电平时选择后 64 列。17 RET L 复位信号，低电平有效。18 VEE -10V LCD

36、12864（不带中文字库）全显控制程式。知道：12864 以及相关的液晶显示器都存在片选，因此在写入要显示的数据时，常常要先处理好片选问题，此问题若是处理不好， 显示的图像就会乱七八糟，我曾经被这个问题困了很久。我曾写了一段程式，自己在电脑上调试一点问题也没有，烧入 IC 中运行却根本，有时连一点显示也没有，查了很长一段时间也没找出原因，那时我急啊多想有位师傅也教教我。初学液晶显示就是这么难！不过经过我半个多月的调试和画逻辑图，还是把它搞定了，下面这些程式中的 WRITE_OUT 子程序为我要编的程序，它是处理对要显示的文字或图像进行自动片选和换行的主程序。也许这对初学液晶显示者都有一点帮助和

37、启发，所以就发出来现丑了。：本人也是初学单片机，此程式可能存在缺陷或冗余，因此参考和学习用，但是此程式绝对可行，我已在我的 12864 液晶（不带中文字库）仿特别真器运行 OK。;单片机：89S51，晶振频率为 12MHz配用不带中文字库的 12864 液晶显示器DIEQU P2.0RWEQU P2.1EEQU P2 2WCSAEQU P2.3WCSBEQU P2.4RSTEQU P2.5LVCCEQU P2.6X EQU 30HY EQU 31H;*以上是接口定义START:0000HMOV SP,#60HLJMP MA N;*主程序地址0040HMAIN:NOPCLR ENOP;复位CLR
