[導讀]12864液晶的驅動和1602的類似，只不過是多了幾個擴展的功能，不如畫圖功能

12864液晶的驅動和1602的類似，只不過是多了幾個擴展的功能，不如畫圖功能：

這里講一下：不要簡單的認為12864是y軸64，x為128，那是點陣的分布，不是讀寫的分布，如正圖表示，y軸的32行，從0到31，x軸的16 從0到15,0到7為上半個屏幕，8到15在下半個屏幕，所以繪圖的時候，有兩個部分要進行書寫

在12864上載入任意一幅圖：

示例代碼：

#include

#define uint unsigned int

#define uchar unsigned char

sbit lcdrs = P2^4;//數據還是指令的選擇端口

sbit lcdwr = P2^5;//讀寫操作端口

sbit lcden = P2^6;//使能端延時端口

sbit PSB = P2^1;//串行數據還是并行數據的選擇段

//圖片的編碼，這幅圖片的編碼是一個哆啦a夢

unsigned char code pic1[] = { /* 0X10,0X01,0X00,0X80,0X00,0X40, */

0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,

write_cmd(0x30);//基本指令操作

write_cmd(0x0c);//開顯示，關掉光標

write_cmd(0x01);//清楚lcd的內容

}

void lcd_putpic(unsigned char code *img)//載入圖畫的函數

{

uint i,j;

//顯示上半個屏幕的內容

for(i = 0;i<32;i++)

{

write_cmd(0x80+i);//垂直的地址

write_cmd(0x80);//水平的地址

for(j=0;j<16;j++)

{

write_date(*img);

img++;

}

//顯示下半個屏幕的內容

for(i = 0;i<32;i++)

{

write_cmd(0x80+i);//垂直的內容

write_cmd(0x88);//水平的地址第三行的內容

for(j=0;j<16;j++)

write_date(*img);

img++;

}

void setpic()//圖像顯示模式設置函數

{

write_cmd(0x36);//選擇8bit的數據流，圖像顯示模式

delay1ms(5);

}

main()

{

init_12864();//初始化液晶

setpic();//初始化液晶圖片顯示

lcd_putpic(pic1);//載入一幅圖片

delay1ms(5);

while(1);

}

以后載入圖片只需要將圖片用取模的軟件，注意圖片的大小必須是128x64的尺寸，否則會出現(xiàn)亂碼，這是個比較容易犯的錯誤，希望大家注意
