[嵌入式]关于单片机控制用字库显示LCD12864汉字

/*选择屏幕screen: 0-全屏,1-左屏,2-右屏*/
void SelectScreen(uchar screen)   
{  
   switch(screen)
   { case 0: LCD12864CS1=0;//全屏

 /*清屏screen: 0-全屏,1-左屏,2-右*/
void ClearScreen(uchar screen)

     uchar i,j;
     SelectScreen(screen);

            {LCDWriteData(0x00); //写点内容，列地址自动加1
              }
     }
}

记录一些学习中遇到的问题。其实LCD12864不用字库用字符组也可显示字符。
