板子是战舰MINI板，用老程序LCD可以正常使用，但移植UCGUI时竖屏正常，横屏始终有问题，右边有一部分无法显示，看了坛子里面有一篇文章(http://www.openedv.com/posts/list/0/43393.htm)，原子哥建议用最新版的程序，我用下了最新的“精英板资料盘(A盘)\4，程序源码\实验13 TFTLCD显示实验”里面的程序，LCD.C是V2.9 20141130版，修改了IO地址，在LCD.h里面改好了分辨率： //LCD分辨率设置
#define SSD_HOR_RESOLUTION             240             //LCD水平分辨率
#define SSD_VER_RESOLUTION             320             //LCD垂直分辨率
为什么LCD没有反应，LCD是好的，LCD的ID是0x8989,检查源码后发现LCD_Init()里面居然没有0x8989的初始化程序，从老程序里面复制代码手动加上去，加入的代码如下：
      }else if(lcddev.id==0X8989)
      {
         LCD_WriteReg(0x0000,0x0001);//打开晶振
         LCD_WriteReg(0x0003,0xA8A4);//0xA8A4
         LCD_WriteReg(0x000C,0x0000);
         LCD_WriteReg(0x000D,0x080C);
         LCD_WriteReg(0x000E,0x2B00);
         LCD_WriteReg(0x001E,0x00B0);
         LCD_WriteReg(0x0001,0x2B3F);//驱动输出控制320*240  0x6B3F
         LCD_WriteReg(0x0002,0x0600);
         LCD_WriteReg(0x0010,0x0000);
         LCD_WriteReg(0x0011,0x6078); //定义数据格式  16位色                横屏 0x6058
         LCD_WriteReg(0x0005,0x0000);
         LCD_WriteReg(0x0006,0x0000);
         LCD_WriteReg(0x0016,0xEF1C);
         LCD_WriteReg(0x0017,0x0003);
         LCD_WriteReg(0x0007,0x0233); //0x0233
         LCD_WriteReg(0x000B,0x0000);
         LCD_WriteReg(0x000F,0x0000); //扫描开始地址
         LCD_WriteReg(0x0041,0x0000);
         LCD_WriteReg(0x0042,0x0000);
         LCD_WriteReg(0x0048,0x0000);
         LCD_WriteReg(0x0049,0x013F);
         LCD_WriteReg(0x004A,0x0000);
         LCD_WriteReg(0x004B,0x0000);
         LCD_WriteReg(0x0044,0xEF00);
         LCD_WriteReg(0x0045,0x0000);
         LCD_WriteReg(0x0046,0x013F);
         LCD_WriteReg(0x0030,0x0707);
         LCD_WriteReg(0x0031,0x0204);
         LCD_WriteReg(0x0032,0x0204);
         LCD_WriteReg(0x0033,0x0502);
         LCD_WriteReg(0x0034,0x0507);
         LCD_WriteReg(0x0035,0x0204);
         LCD_WriteReg(0x0036,0x0204);
         LCD_WriteReg(0x0037,0x0502);
         LCD_WriteReg(0x003A,0x0302);
         LCD_WriteReg(0x003B,0x0302);
         LCD_WriteReg(0x0023,0x0000);
         LCD_WriteReg(0x0024,0x0000);
         LCD_WriteReg(0x0025,0x8000);
         LCD_WriteReg(0x004f,0);       //行首址0
         LCD_WriteReg(0x004e,0);       //列首址0
      }
然后屏幕有了显示，背景也在自动变色，只是文字显示是乱码，背景在自动切换的时候，发现是斜着刷屏的，这是BUG吗？原子哥，还是故意为之啊，要抛弃ID为8989的屏吗，怎么改进，改好后移植UCGUI，还会出现以前的问题吗？@正点原子
