[嵌入式]LCD显示汉字，取模软件PCtoLCD2002完美版

一、LCD显示汉字结果展示：

?二、取模软件的使用（PCtoLCD2002完美版）

????????1. 打开软件，点击菜单栏【选项】，打开字模选项

????????勾选阴码点阵、逐列式取模、顺向（高位在前，低位在后）、C51格式。

????????2.在下方栏目中输入欲显示的汉字，此时设置的字宽16，字高16。

????????点击右下方【生成字模】，即可显示在下方。可选中十六进制数部分，右击【复制】然后粘贴到编程软件里。

3.说明

????????字宽16，字高16，逐列式取模

????????高度16个位可拆分为16/8=2字节，高度16*宽度16 = 2字节*宽度16 = 32字节控制一个字符显示。

OLED显示-字库码表原理_BraveWangDev的博客-CSDN博客_oled显示字符原理一,字库和码表在OLED显示屏上显示字符,和在点阵上显示图像是一样的 都是通过区域内的像素点的量暗来呈现图案 以1608字体码表为例,代码中表现如下:const unsigned char asc2_1608[95][16]={ {0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}https://blog.csdn.net/ABAP_Brave/article/details/53539837?spm=1001.2014.3001.5506

????????2412字体：即高度24*宽度12，

????????高度24个位可拆分为24/8=3字节

????????高度24*宽度12 = 3字节*宽度12 = 36字节控制一个字符显示。

三、汉字显示代码

????????在正点原子【?TFT LCD液晶显示实验】程序上进行修改：

????????1.【lcd.c】文件中增加显示汉字的函数，并在【lcd.h】文件中进行声明。

????????void Chinese_Show_one(u8 x, u8 y, u8 num, u8 size, u8 mode);

????????注意：temp = chinese[num][t]; ?//这个数组需要在【font.h】文件中增加

void Chinese_Show_one(u8 x, u8 y, u8 num, u8 size, u8 mode)
{
    u8 temp,t,t1;
    u8 y0=y;
    u8 csize=(size/8 + ((size%8)?1:0)) * size;     //     16/8+1
    for(t=0;t<csize;t++)
    {  
        if(size==16)     
					temp = chinese[num][t];     //这个数组需要在【font.h】文件中增加
        else 
					return;      
        for(t1=0;t1<8;t1++)
        {
            if(temp&0x80) 
							LCD_Fast_DrawPoint(x,y,POINT_COLOR);
            else 
							LCD_Fast_DrawPoint(x,y,BACK_COLOR);
            temp<<=1;
            y++;
            if((y-y0)==size)
            {
                y=y0;
                x++;
                break;
            } 
         }  
     }  
}

????????2. 【font.h】文件新增数组?const unsigned char chinese[10][36]

const unsigned char chinese[10][36]={
	
{0x08,0x20,0x06,0x20,0x40,0x3E,0x30,0xC0,0x03,0x01,0x40,0x01,0x78,0x02,0x47,0x04,0x40,0xC8,0x40,0x30,0x40,0xC8,0x47,0x04,0x78,0x02,0x00,0x01,0x00,0x01,0x00,0x00},/*"汉",0*/

{0x02,0x04,0x02,0x08,0x42,0x10,0x42,0x60,0x42,0x00,0x42,0x02,0x42,0x01,0x43,0xFE,0x42,0x00,0x42,0x00,0x42,0x00,0x42,0x40,0x42,0x20,0x02,0x10,0x02,0x0C,0x00,0x00},/*"示",3*/
