基于UCOS-III+emWin+FatFs+Lwip（uip）+USB的综合例程主界面设计
&( 09:00:02)
完整设计，视频演示以及代码下载，看这个帖子：（1）一共设计了20个图标,，图标大小64*64，图标采用带Alpha通道的BMP图片，本打算用PNG，但是现在的
&&&&&5.16版本不支持，使用了相应的函数提示函数不存在，可以确定是库的问题，貌似5.18修正了，我提
&&&&&供的emWin移植方法无法在这个5.18上面使用，需要等到MDK上自带的emWin升级到5.18就可以使用了。
（2）图标的显示采用了ICONVIEW控件，简单好用
（3）图标下面建立了一个水平窗口，用于显示时间和CPU的使用率
（4）背景图标采用在回调函数里面重绘的方式实现，这样实现的话，好处多多。
（5）右下角的RTC显示还没有做，后面逐渐添加上去。
最终界面如下，右下角添加WM8978的音量调节，网络设置，RTC.

:有个API EDIT_GetText的函数的。 ( 16:19) 谢谢，实验，可以的，谢谢大神
光标闪烁可能与RA8875的驱动函数有关。 如果没有特别要求，建议不用闪烁这个功能。我以前用的时候，光标闪烁频率不均匀，时快时慢，可能运行的任务太多了。
关于光标闪烁要改下这个驱动：

Time 0.047657 second(s),query:2 Gzip enabled原始的例程没有竖屏，
自己做了个四向变换（编译时确定）
有需要的可以拿去，不用打招呼。
基于旺宝红牛版开发板做的。
&修改 LCDConf.h &文件里的 ORIENTATION 宏 则可改变方向。
(注意，横竖屏切换后，对于固定大小显示的emWin界面并不能直接适应屏幕）。

如何移植 emWin 网上有大量的列子和教材，我就不在这里说明。
emWin 是不开方源代码的，所以 ucgui 使用三个宏来切换的横竖屏的方法不使用。而且即使可用运行效率也不高。
我说下我的横竖屏切换是如何做到的。
首先我们观察 emWin &和 & 显示屏驱动之间如何连接的。 emWin 到底调用了那些驱动函数来显示界面。
_SetPixelIndex 里调用了 &LCD_PutPixel(x,y,PixelIndex);
_GetPixelIndex 里调用了 &LCD_GetPixel(x,y);
_DrawHLine & & 里调用了 &LCD_DrawLineH(x0, y, x1, LCD_COLORINDEX);&
_DrawVLine & & 里调用了 &LCD_DrawLineV(x, y0, y1, LCD_COLORINDEX);//该函数我自己重写的，原例程里没有
_FillRect & & & & &里调用了 & &LCD_SetTarBlock(x0, y0, x1, y1);
//该函数我自己重写的，用来替代RA8875_SetTarBlock .让程序更模块化
//这个很多新接触emWin 的人很容易漏掉下面这个地方。如果移植后，基础GUI接口显示正常，而图片，wigt 控件显示不正常，都是下面这个被调用的函数不正确。
_DrawBitLine16BPP 里调用了&LCD_DrawHColorLine(x, y, xsize, (uint16_t *)p); &//这个函数实现最麻烦，RA8875 没有找到垂直自增长的填充方式，最后用的画图的方式实现了。
_DrawBitLine32BPP 里也调用了LCD_DrawHColorLine(x, y, xsize, (uint16_t *)p) //这个调用是错误的，会导致颜色显示不对。但是我用的16位（565）色深，所以不会调用到这个。使用真彩色的需要注意，凡是带了color 的地方都要改成32位才能正确显示颜色。
打开GUIDRV_Template.c 这个文件咱们看看调用关系。

好了，所有关联函数都在这了，就是前面提到的六个函数
这六个函数的位置都放置在&bsp_tft_lcd.c 文件里，我们接着看bsp_tft_lcd.c 文件
我用了一个宏_LCD_SWAP_XY .来决定编译时是编译成横屏还是竖屏。_LCD_SWAP_XY =0 时为横屏。
各位可以直接在下面的代码里看看横屏和竖屏执行的代码的不同。
而 横屏和竖屏能正确显示后，剩余的两个方向，只是 XY 轴翻转的问题，我使用RA8875 自带的设置其扫描方向来实现翻转（省了好多事，只需设置好RAh寄存器就可以了）

接下来就是触摸屏坐标的映射，不同的显示方向。需要映射不同的触摸点 X,Y 的值。否则 触摸就是乱来的。
在触摸屏驱动文件gt9xx.c 中，我将
point_x = ((point_data[5]&&8) | point_data[4]);
point_y = ((point_data[3]&&8) | point_data[2]);
#if(!_LCD_SWAP_XY && !LCD_FLIP)
point_x = _LCD_WIDTH - 1 - ((point_data[5]&&8) | point_data[4]);
& & & & point_y = _LCD_HEIGHT - 1 - ((point_data[3]&&8) | point_data[2]);
#elif(_LCD_SWAP_XY && !LCD_FLIP)

point_y = ((point_data[5]&&8) | point_data[4]);
#elif(!_LCD_SWAP_XY && LCD_FLIP)
point_x = ((point_data[5]&&8) | point_data[4]);
point_y = ((point_data[3]&&8) | point_data[2]);

point_x = ((point_data[3]&&8) | point_data[2]);
point_y = &_LCD_HEIGHT - 1 - ((point_data[5]&&8) | point_data[4]);
好了，到这里驱动上的修改基本完成。
接下来就是 LCDConf.c 和 LCDConf.H 两个文件。
我在 &LCDConf.H&文件中 进行宏定义如下：
#define &ORIENTATION & 0 & // 屏幕显示方向 & 取值范围 0 90 180 270
#if &ORIENTATION==0

#define _LCD_WIDTH &LCD_HEIGHT
ORIENTATION & 宏 即使控制屏幕显示方向的总开关。
在LCDConf.C 中，屏幕(emWin 所感知到的屏幕)的高度和宽度，以及 触摸 的 限值需要根据 宏定义进行调整，
我修改成下面这样。
#define XSIZE_PHYS &_LCD_WIDTH
#define YSIZE_PHYS &_LCD_HEIGHT
#define VXSIZE_PHYS _LCD_WIDTH
#define VYSIZE_PHYS _LCD_HEIGHT
#define GUI_TOUCH_AD_TOP & & 0 &
#define GUI_TOUCH_AD_BOTTOM &_LCD_HEIGHT
#define GUI_TOUCH_AD_LEFT & &0 &&
#define GUI_TOUCH_AD_RIGHT & _LCD_WIDTH
到这里，所有的工作都完成了。
