- 一、获取源码
- 二、在visual Studio 上实现仿真
- 三、移植littleVGL 到STM32上
- 总结
- 附录
- lv_conf.h 源码
一、获取源码
注意，以下选用的littleVGL 版本为：v7.7.0
提前安装好 Visual Studio 2019
安装好 keil MDK
在github 上获取源码：https://github.com/lvgl/lvgl.git
获取demo源码：https://github.com/lvgl/lv_demos.git
获取littleVGL 驱动源码：https://github.com/lvgl/lv_drivers.git
获取Visual Studio 仿真工程源码：https://github.com/lvgl/lv_sim_visual_studio.git
如图：
二、在visual Studio 上实现仿真
- 将 lv_demos-7.7.0 文件夹下的所有文件拷贝到 lv_sim_visual_studio-7.7.0\visual_studio_2017_sdl\lv_examples中
- 将lv_drivers-7.7.0文件夹下的所有文件拷贝到lv_sim_visual_studio-7.7.0\visual_studio_2017_sdl\lv_drivers中
- 将lvgl-7.7.0文件夹下的所有文件拷贝到lv_sim_visual_studio-7.7.0\visual_studio_2017_sdl\lvgl中
- 双击打开 lv_sim_visual_studio-7.7.0文件夹下的lv_sim_visual_studio_sdl.sln
如图：
5. 运行示例代码
如图：
效果如图：
三、移植littleVGL 到STM32上
注意：本人使用的是STM32F103VCT6平台
- 在整个工程文件目录下新建GUI、GUI_APP文件夹
如图：
- 在GUI 文件夹下新建三个文件夹：lv_drivers、lv_examples、lvg（个人习惯）
如图：
- 将lvgl-7.7.0\lvgl-7.7.0\examples\porting中的所有文件拷贝到上一步的lv_drivers中，并将后面的 _template 删除（个人习惯）
如图：
- 将 E:\01.MCU\05.GUI\sim\lvgl-7.7.0\lvgl-7.7.0\src中所有文件拷贝到第二步中的 lvg文件夹中。
如图：
- 将 lv_demos-7.7.0 文件夹中的文件全部拷贝第二步中的lv_examples文件夹中。
如图：
- 在keil 工程目录中新建三个文件分支（如图1），并把 GUI\lvg\src下的文件的C文件全部添加到GUI分组下（如图2）。
图1：
图2:
- 把 lv_examples下的 lv_ex_conf_template.h拷贝到 GUI目录下（图1），
把lvg文件目录下的lv_conf_template.h拷贝到GUI目录下（图2）。并改为如图3所示。
图1：
图2：
图 3：
8. 在GUI_Drives 分组下添加 lv_drives文件夹中的 lv_port_disp.c（图1），并打开lv_port_disp.c文件，使能文件（图2），往下滑，在 ==lv_port_disp_init(void)==函数下选择一个缓存方案（如图3），我选择方案1，继续往下滑，找到 ==static void disp_flush(lv_disp_drv_t * disp_drv, const lv_area_t * area, lv_color_t * color_p)==函数添加液晶的打点函数（如图4）
图1：
图2：
图3：
图4：
接下来就是添加路劲了
如图：经过以上几步就算移植完成了（比较啰嗦），接下来是配置littleVGL,打开工程中GUI目录下的lv_conf.h文件（只要能打开啥软件都可以），选择使能或不使能相关功能（如图2），我的配置源码在后面的附录。
图1：
图2：
添加littleVGL节拍，这里通过定时器实现，时间1ms
如图：
接下来打开 GUI\lv_examples\src\lv_ex_widgets\lv_ex_keyboard文件下的 lv_ex_keyboard_1.c文件（如图1），拷贝里面的代码（如图2），将拷贝的代码粘贴到main 函数下（如图3），并初始化液晶定时器等。
注意： 我这里为了方便演示，不是很规范，规范一点就把.c文件拷贝到GUI_APP文件夹下，并在keil工程中添加到GUI_APP分组下。
图1：
图2：
图3：
- 编译下载到STM32板子，效果如图，OK
总结
通过移植发现各个版本之间还是有一定的差距，不过差距都不是很大。
之前我把littleVGL移植到STM32 HAL库的工程，一个很简单的Demo都爆空间不足，后来我改用标准库后就完美结局空间不足的尴尬局面，不难发现，如果使能了全部控件后，对MCU FLash 是个不小的考验。
