emWin GUIBuilder做的一个界面在F429I-DISCO上不显示
本帖最后由 yuiij 于 2016-2-12 01:04 编辑用的是STM32Cube_FW_F4_V1.11.0\Projects\STM32F429I-Discovery\Applications\STemWin\STemWin_HelloWorld这个例程，把builder生成的.c文件加入了工程，然后用生成的一个函数---CreateWindow();替换了MainTask（）函数里的代码。编译通过后，下载到板子里，黑屏。调了好长时间，就是什么都不显示。。下面是Builder生成的代码：/*********************************************************************

复制以上代码即可运行,是因为你没有对界面进行刷新. MainTask() 函数不能删掉的， 你的 主函数应该调用的是 MainTask();
然后MainTask() 改为调用 CreateWindow() feiting94 发表于 2016-2-12 09:10

是的，我没动main函数里的代码，就是把Create Window放在MainTask里调用的。 :):):):):) 请问楼主：我没有用操作系统，在main.c中先声明，再调用，也出不来啊。
声明：
extern WM_HWIN CreateFramewin(void);
调用：
CreateFramewin();
搞清楚了。原来需要在主循环中添加GUI_Delay（M）。据说目的是运行GUI_Exec()。
