無字庫LCD12864液晶同時顯示大小漢字,有圖有單片機程序含全部資料

ID:110903 · 發表于 2018-9-6 21:35

近日從電路板上拆下一批無字庫的LCD12864液晶屏，為了測試屏的好壞，特地寫了測試程序，結果幾十塊屏全部都是好的！
先來看看實物圖片
正面

背面

引腳功能

時序圖與LCD1602一樣

大漢字取模方法

最終效果圖

只要加入時間和18B20溫度傳感器，就成時鐘和溫度計

部分主要程序
12864初始化：
lcd12864.c

sbit e=P3^4;
sbit rw=P3^6;
sbit rs=P3^5;
sbit cs1=P3^7;
sbit cs2=P3^3;
sbit duan=P2^7; //定義74H373的控制引腳，
sbit wei=P2^6;
void lcd12864_write_com(uchar com) //寫指令
{
rs=0;rw=0;e=0;
P0=com;
e=1;
delay(5);
e=0;
}
void lcd12864_write_date(uchar date)//寫數據
{
rs=1;rw=0;e=0;
P0=date;
e=1;
delay(5);
e=0;
}
void lcd12864_init() //初始化
{
lcd12864_write_com(0xc0); //行的初始化地址
lcd12864_write_com(0xb8);//頁的初始化地址
lcd12864_write_com(0x40);//列的初始化地址
lcd12864_write_com(0x3f);//打開屏幕，關閉是3e
}
void clear_lcd12864() //清屏
{
uchar i,j;
cs1=1;cs2=1; //打開左右兩屏，實物注意：LCD12864實物是CS1=1;CS2=1為打開，
for(i=0;i<8;i++) //共8頁
{
lcd12864_write_com(0xb8+i);//頁的初始化地址
lcd12864_write_com(0x40);//列的初始化地址
for(j=0;j<64;j++) //共64列
{
lcd12864_write_date(0x00);
}
}
}
