一、裸机移植STemWin

二、uC/OS移植STemWin

---

芯片为STM32F103C8T6 

一、下载STemWin源码

进入官网https://www.st.com选择工具与软件 -> 嵌入式软件 -> STM32微控制器软件

 -> STM32Cube MCU和MPU包，根据自己的产品型号点击"Open software page"即可

解压后，源码就在STM32Cube_FW_F1_V1.8.0\Middlewares\ST\STemWin文件夹中

二、裸机移植

2.1、导入文件 

移除多余文件及文件夹，剩下Config、inc、Lib和OS文件夹，Config是配置GUI和LCD，inc是小控件的头文件，Lib是依赖包，STemWin没有开放源码，是以依赖包的形式提供，以前的版本是.lib，现在变为.a，后续导入需要配置IDE。Lib和OS里面的文件，裸机开发选不带OS的，否则就选带OS的，LCD配置文件可以根据个人的LCD驱动器选择，我的LCD驱动器为ST7735，所以选择LCDConf_FlexColor_Template.c

Lib依赖文件选择STemWin_CM3_wc16.a，右击文件，选择Options for file

File Type选择Library file即可 

裸机移植需要导入的.c文件和依赖文件如下： 

2.2、修改文件

STemWin需要修改的文件有Config的配置文件和inc的个别头文件，把要修改的文件清除只读属性，我是用Notepad++打开的文件，右击鼠标选择清除只读属性即可编辑，文件名也修改了

①、修改GUIConf.c的内存分配空间，#define GUI_NUMBYTES  0x2000 ，否则会导致空间不足

②、修改GUIDRV_Template.c（我改为GUIDRV.c），把LCD驱动函数的画点、读点、填充和画线等函数添加到GUIDRV_Template.c里面，如下：

③、修改LCDConf_FlexColor_Template.c（我的修改为LCDConf.c），必须要有LCDConf.h头文件，否则会报错

 GUICC_565替换为GUICC_M565，否则设置GUI_SetColor时颜色对不上

④、修改GUIDRV_FlexColor.h的硬件加速API定义

因为GUIDRV_Template.c（GUIDRV.c）里面定义的API函数定义的是const GUI_DEVICE_API GUIDRV_Template_API，所以要修改GUIDRV_FlexColor.h，否则执行GUI_Init();会卡死
