51单片机LCD12864绘图

LCD12864绘图方法如下：一、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D7-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：voidLCD12864_RAM_Cls(){u8x,y;//xy坐标LCD_write_comm(0x34);//使用扩充指令集LCD_delay();for(y=0;y32;y++){LCD_write_comm(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.hunsignedcharcodePicture[]=//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,0x00,0x00,0xD8,0x00,0x00,0x00,0x00,0x01,0x80,0x0F,0x7B,0x63,0xE0,0x00,0x00,0x22,0x00,0x01,0x24,0x00,0x00,0x00,0x00,0x01,0x80,0x0F,0xFB,0x63,0x07,0x34,0x00,0x14,0x00,0x01,0x04,0x00,0x00,0x00,0x00,0x01,0x80,0x0D,0xDB,0x63,0x01,0xBC,0x00,0x08,0x00,0x00,0x88,0x00,0x00,0x00,0x00,0x01,0x80,0x0C,0x1B,0x63,0x07,0xB0,0x00,0x00,0x00,0x00,0x50,0x00,0x00,0x00,0x00,0x01,0x80,0x0C,0x1B,0x63,0xED,0xB0,0xDB,0x00,0x01,0x00,0x20,0x00,0x00,0x00,0x00,0x01,0x80,0x0C,0x19,0xE1,0xE7,0xB0,0xDB,0x00,0x02,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x0C,0x19,0xE1,0xE7,0xB0,0xDB,0x00,0x02,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x60,0x00,0x00,0x00,0x00,0x04,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x03,0xC0,0x00,0x00,0x00,0x00,0x08,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x08,0x05,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x10,0x0A,0x80,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x0A,0x00,0x00,0xFF,0xF8,0xE0,0x05,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x06,0xC0,0x15,0x00,0x1F,0xFF,0xFF,0xC0,0x02,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x09,0x20,0x11,0x00,0xFB,0xFF,0xE1,0xF8,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x08,0x20,0x0A,0x03,0x9F,0x00,0x9E,0x3E,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x04,0x40,0x04,0x0E,0x70,0x00,0x81,0xC7,0x80,0x01,0x40,0x00,0x00,0x00,0x01,0x80,0x02,0x80,0x00,0x1D,0x80,0x00,0xE0,0x61,0xE0,0x02,0xA0,0x00,0x00,0x00,0x01,0xC0,0x01,0x00,0x00,0x77,0x9F,0xFC,0xF0,0x18,0xF8,0x02,0x20,0x00,0x00,0x00,0x01,0xC0,0x00,0x00,0x01,0xDF,0x00,0x00,0xF3,0x0C,0x3C,0x01,0x40,0x00,0x00,0x00,0x01,0xC0,0x00,0x00,0x03,0x9E,0x00,0x00,0xF8,0x06,0x1E,0x00,0x80,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x07,0x0E,0x30,0x01,0xFC,0x7F,0x07,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x07,0x0E,0x30,0x01,0xFC,0x7F,0x07,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x7E,0xFF,0xFF,0xFF,0xFF,0xFF,0x83,0xC0,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x0F,0xFD,0xFF,0xFF,0xFF,0xFF,0xFC,0x01,0xF0,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x3F,0x81,0xFF,0x00,0x00,0x00,0x00,0x1F,0xF0,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0xFE,0xF0,0x00,0x00,0x01,0x00,0x00,0xC0,0x1C,0x00,0x00,0x00,0x00,0x01,0x80,0x03,0xC0,0x07,0x80,0x00,0x03,0xE0,0x07,0x00,0x1C,0x00,0x00,0x00,0x00,0x01,0x80,0x03,0x80,0x03,0x60,0x00,0x03,0xE0,0x0C,0x00,0x0E,0x00,0x00,0x00,0x00,0x01,0x80,0x07,0x00,0x00,0xC0,0x00,0x00,0x20,0x18,0x00,0x07,0x00,0x00,0x00,0x00,0x01,0x80,0x09,0x01,0x80,0x60,0x00,0x00,0x20,0x73,0x9F,0x03,0x80,0x00,0x00,0x00,0x01,0x80,0x1E,0x0F,0xF2,0x20,0x00,0x00,0x20,0x67,0xFF,0xC1,0xC0,0x00,0x00,0x00,0x01,0x80,0x1E,0x1F,0xF9,0x30,0x00,0x00,0x20,0xEF,0xFF,0xE0,0xE0,0x00,0x00,0x00,0x01,0x80,0x38,0x3F,0xFC,0x90,0x00,0x00,0x20,0xCB,0xFF,0xF9,0xF0,0x00,0x00,0x00,0x01,0x80,0x7F,0x7F,0xFE,0x10,0x00,0x00,0x20,0xDB,0xFF,0xFF,0xF0,0x00,0x00,0x00,0x01,0x80,0x6E,0xF9,0xBF,0x10,0x00,0x00,0x20,0xF7,0xED,0xFF,0xF0,0x00,0x00,0x00,0x01,0x80,0x7C,0xFC,0x3F,0x10,0x00,0x00,0x20,0x67,0xE1,0xFD,0xE0,0x00,0x00,0x00,0x01,0x80,0x7C,0xFC,0x3F,0x10,0x00,0x00,0x20,0x67,0xE1,0xFD,0xE0,0x00,0x00,0x00,0x01,0x80,0x38,0xFC,0x3F,0x18,0x00,0x00,0x20,0x87,0xE0,0xFD,0xC0,0x00,0x00,0x00,0x01,0x80,0x38,0xF1,0x8F,0x18,0x00,0x1F,0xE7,0x87,0x9C,0x7D,0xC0,0x00,0x00,0x00,0x01,0x80,0x1C,0xFE,0x1F,0x81,0xFF,0xFF,0xC0,0x0F,0xE0,0xFF,0x80,0x00,0x00,0x00,0x01,0x80,0x0C,0xFC,0x3F,0x80,0x00,0x00,0x00,0x0F,0xE1,0xF8,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0xF9,0xBF,0xFF,0xFF,0xFF,0xFF,0xFF,0xEC,0xFE,0x00,0x00,0x00,0x00,0x01,0x80,0x03,0xF9,0xBF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xC0,0x00,0x00,0x00,0x01,0x80,0x0F,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xC0,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x03,0x80,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
