uCOSIII uCGUI STM32 平台移植（转）

2万 · 2013-11-30 21:44

一、环境：
软件:

STM32F10x 3.5固件库。
MDK4.23 编译器。
uCos-III v3.03。
uCGUI v3.98。

硬件：

神舟三号开发板STM30F103ZE芯；
3.2寸屏320*240。
SPI接口的触摸板。

二、资料
这是我搜集到的资料，都存现在网盘上了。现在115不好用了，只好换百度。
ucGUI中文手册.pdf
http://pan.baidu.com/share/link?shareid=25403&uk=118334538
UCGUI3.98源码.rar
http://pan.baidu.com/share/link?shareid=25407&uk=118334538
官方UCGUI4.04, 及说明书
http://pan.baidu.com/share/link?shareid=25413&uk=118334538
http://pan.baidu.com/share/link?shareid=25415&uk=118334538

下面上两个版本空的工程：
　　　 FWLib3.5+uCOSIII3.03
      http://pan.baidu.com/share/link?shareid=25418&uk=118334538
      FWLib2.0+uCOSIII3.03
      http://pan.baidu.com/share/link?shareid=25419&uk=118334538
      提示:

下文的移植都是在FWLib3.5+uCOSIII3.03这个工程上进行的。
这两个工程STM32F固件没有完整添加，在用到哪个功能就添加哪个(减少编译量)。

在移植前最好看过一遍uCGUI中文手册，这样可以有个初步了解，和操作使用。建立工程时用他推崇的结构：

三、开始准备移植文件：
新建文件夹uCGUI

复制UCGUI3.98源码\uC-GUI-V3-98\Micrium\Software\uC-GUI\Start整个GUI和 Config文件夹到uCGUI。
复制UCGUI3.98源码\uC-GUI-V3-98\Micrium\Software\uC-GUI\Sample\GUI_X 下GUI_X_Touch.c，GUI_X_uCOS.c两个文件到uCGUI中，因为有触摸功能和uCOS系统。
复制UCGUI3.98源码\uC-GUI-V3-98\Micrium\Software\uC-GUI\Sample下整个GUIDemo文件夹到uCGUI。
在uCGUI文件夹下新建LCDDriver文件夹，把自己lcd的驱动程序写入其中。我新建的ili9320.c 和ili9320.h两个文件。需要写哪什么驱动函数，后面做详细的介绍。

图3
到此文件的准备就完成了，开始向程序中添加。

四、添加到工程
我还是直接上图，添加哪些文件。

图7

2万 · 2013-11-30 21:48

直接添加所有Dome中的文件。

图8

2万 · 2013-11-30 21:49

添加所有GUI子文件。太多了，还是用CTRL+A吧，不然手都要点麻！

图9
重要的一步，让添加的文件可直接索引到。
好了，所有文件都添加到工程中了。下面是最后重要的一步，对文件进行修改。

2万 · 2013-11-30 21:49

五、移植修改文件
LCD的驱动，这一步也关系到LCD显示的成功于否，主要要写三个函数：
void LCDxxx_Init(void);　　//LCD硬件初始化
u16 LCDxxx _GetPoint(u16 x,u16 y);　　//获取(x,y)坐标的像素点
void LCDxxx _SetPoint(u16 x,u16 y,u16 point);　　//把像素点写入(x,y)坐标点
这三个函数以定要再在自己的开发板上测试好了，再复制过来。LCDxxx函数名可自定义。只要这三个函数没有问题，移植就成功一大半了
我的是：
void ili9320_Initializtion(void);
u16 ili9320_GetPoint(u16 x,u16 y);
void ili9320_SetPoint(u16 x,u16 y,u16 point);

写好后，在uCGUI\GUI\LCDDriver下找到LCDTemplate.c文件。
找到LCD_L0_SetPixelIndex 添加ili9320_SetPoint函数；
找到 LCD_L0_GetPixelIndex添加ili9320_GetPoint函数。

在uCGUI\Config找到三个配置文件。
LCDConf.h
在pdf的第20章有详细介绍
图10

2万 · 2013-11-30 21:50

先设定这几个必需的。
初始化宏定义
驱动如果是自己写的需要以下宏定义
#define LCD_CONTROLLER -1
#define LCD_INIT_CONTROLLER() ili9320_Initializtion();

GUIConf.h
可以用默认配置

GUITouchConf.h
先用默认值，等运行Dome后，有个校准，获得校准值，再进行修改。

GUI_X_Touch.c文件修改

主要添加读X轴和Y轴的AD值。如果和我用同样的开发板，可以用如下代码。
