发现一个新的GUI，很小巧，心就痒痒了，想试试，目前官方版本是v0.3，官方网站也只提供了f429的demo，但是因本人见识较少，不知道那工程是什么后缀STM32F429.coproj，无奈，就就自己移植一下玩玩了，权当娱乐了。 下班回到家，把f429的discover板子找了出来，已经放了3年了，竟然还能亮起来，很兴奋啊。又从网上找了个discover的例程能点亮ltdc的。万事具备了。 先把GUI介绍一下， What is μGUI μGUI is a free and open source graphic library for embedded systems. It is platform-independent and can be easily ported to almost any microcontroller system. As long as the display is capable of showing graphics, μGUI is not restricted to a certain display technology. Therefore, display technologies such as LCD, TFT, E-Paper, LED or OLED are supported. The whole module consists of two files: ugui.c and ugui.h. μGUI Features
μGUI Requirements μGUI is platform-independent, so there is no need to use a certain embedded system. In order to use μGUI, only two requirements are necessary:
一大早睡不着了，就起来开始移植，花了近2小时，终于移植成功了，当然还没有完成触摸的移植。下面开始汇报一下。 找了个非常干净的例程，里面除了驱动，就是ADC例程，直接删除即可开始移植了。 先上个图看看。  把官方例程的  这几个文件拷贝过来，放到一个文件夹里。把官方例程里的system.h头文件换成例程的Com.h，当然头文件里要增加上图4个c文件的头文件即可。解决几个小的错误，把delay.c里的初始化直接删除，然后在main.c文件中清除些之前工程的函数及变量等，把官方例程main.c文件中的函数，及相关代码拷贝过来即可。需要拷贝的有 /* GUI structure */ UG_GUI gui;
