Question

求个单片机控制12864ZB液晶屏的简单程序

型号12864ZB
BLWABBA 5.0V
只要能输出数字就好。。。
多谢。。。
=.=么有人鸟我。。
真的是只需要一个。。。能让俺液晶屏亮起来能出字的小程序。。。
ARDUINO网站上的示例试过了不行。。。
就比如下面这个程序，运行但是液晶屏只是全屏亮。。
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
lcd.print("hello, world!");
}
void loop() {
}
在线等
(再强调下。。是用arduino..谢谢几位的回答但是都没有解决问题..)

在使用下例程序之前要先根据你的电路定义你的IO口
#include <reg52.h>
#include <intrins.h>
#include <string.h>
#include <stdio.h>

#define uchar unsigned char // 8bit, 0 ~ 255
#define uint unsigned int // 16bit, 0 ~ 65,535
#define ulong unsigned long // 32bit, 0 ~ 4,294,967,295

Answer 3

前面几个回答给的都是89c52的代码，跟avr不兼容。你自己帖的这个arduino不是12864的代码，是1602的，我做arduino实验的时候用过。
12864的驱动库官方是没有带的。淘宝上卖12864的卖家手里有库文件和例子程序。你可以向已经买过该宝贝的买家要一个。 淘宝里搜索 arduino 12864 然后点开宝贝，看谁买过并在线。然后弹对方消息。^_^

Answer 4

一般控制方法都是通用的吧,
RS,RW ,E是关键
