• 48x48中文字体取模说明

尺寸设置如下图所示：

取模成功后需要定义以下结构体数组存放取模数据（结构体定义见中英文显示取模设置）：

const typFNT_GB48 tfont48[]=
{
    "中",0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x03,0x00,

函数定义如下：

void GUI_DrawFont48(u16 x, u16 y, u16 fc, u16 bc, u8 *s,u8 mode)

    for (k=0;k<HZnum;k++) 
    {

        { 	
            LCD_SetWindows(x,y,x+48-1,y+48-1);
	    for(i=0;i<48*6;i++)
	    {
	        for(j=0;j<8;j++)
		{
		    if(!mode) //非叠加模式：字体带有背景色，显示时会将原来显示的内容覆盖掉
		    {

                        {

			}
		    }
		}
	    }
        }				  	
        continue;  //查找到对应点阵字库立即退出，防止多个汉字重复取模带来影响
    }	
    LCD_SetWindows(0,0,lcddev.width-1,lcddev.height-1);//恢复窗口为全屏  
}
