1、LCD12864绘图方法如下：1、 绘图方法： 1、使用扩展指令集并关闭绘图显示 2、输入y轴坐标3、输入x轴坐标4、写入数据D15-D85、写入数据D7-D06、开绘图显示7、返回普通指令对应程序如下：LCD_write_comm(0x34);/使用扩充指令集LCD_delay();LCD_write_comm(0x80+y);/y坐标起始地址LCD_delay();LCD_write_comm(0x80+x);/x坐标起始地址LCD_delay();LCD_write_date(0x55);/写入数据D15-D8LCD_delay();LCD_write_date(0x55);/写入数据D
2、7-D0LCD_delay();LCD_write_comm(0x36);/显示RAMLCD_delay();LCD_write_comm(0x30);/退出扩展指令集LCD_delay();程序执行效果则是第一行的第1-16个像素点会描出0x5555的二进制像素点，则后面的整个屏幕则是花屏，如果只想看到这0x5555,这几个像素点，则必须要给LCD的RAM重新赋值，也可以说是清屏，程序如下：void LCD12864_RAM_Cls()u8 x,y;/xy坐标LCD_write_comm(0x34);/使用扩充指令集LCD_delay();for(y=0;y32;y+)LCD_write_c
3、omm(0x80+y);/y坐标起始地址LCD_delay();LCD_write_comm(0x80);/x坐标起始地址LCD_delay();for(x=0;x16;x+)LCD_write_date(0x00);LCD_delay();LCD_write_date(0x00);LCD_delay();LCD_write_comm(0x36);/显示RAMLCD_delay();LCD_write_comm(0x30);/退出扩展指令集LCD_delay();二、坐标与显示X轴坐标设定初始值后会自动加1，取值范围0-15Y轴需要人为加1，取值范围为0-31整个屏幕分为上下屏，上屏对应坐标为
4、x(0-7)y(0-31),下屏对应坐标为x(8-15)y(0-31)三、LCD12864图片显示代码1、 Main.c#includecommon.h#includedelay.h#include12864.hunsigned char code Picture= / 图片数据表/此处添加图片取模16进制码共1024Byte,取模方式：从左到右从上到下0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x14,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x06,0x30,0x01,0xE0,0x00,0x00,0x2A,0x
