移植 lvgl
LVGL V8.3.11对于资源的要求
- 最低配置
- FLASH ~32 KB 仅基础核心 + 1-2 个控件，无字体，无图像解码
- RAM ~8 KB 仅用于基本缓冲区，无帧缓冲
- 典型配置
- FLASH ~100-150 KB 核心库 + 常用控件（按钮、标签、滑块、列表等）+ 1-2种字体 + 基础图像解码
- RAM ~10-32 KB 显示缓冲区（通常 1/10 屏幕大小）+ 控件对象内存
- 完整功能
- FLASH ~500 KB - 1 MB+ 全部控件 + 多种字体 + 图像解码器（PNG/JPEG/BMP/GIF）+ 动画引擎 + 抗锯齿
- RAM ~50 KB - 200 KB+ 完整帧缓冲 + 控件对象 + 动画数据
本次移植采用FreeRTOS移植章节为基础，即stm32f103c8t6展示添加LVGLUI库的移植。 STM32F103C8T6 FLASH=64KB RAM=20KB, 资源非常紧张。 选取的LVGL版本为体积更小的V8.3.11版本，裁剪到动画等功能，并且通过Release优化体积，才勉强能够运行。 所以在实际项目中，应该选取更大的FLASH及RAM。或更换U8g2更小的图形库。

移植
添加屏幕驱动及测试
- 这里的屏幕采用的是
SSD1315,参照以下内容添加文件及内容 - 同时在
main.c中添加了，对于屏幕的测试 - 编译下载、成功后屏幕应该能够正常刷新

* LVGL requires a buffer where it internally draws the widgets.

* The buffer has to be greater than 1 display row
*
* There are 3 buffering configurations:
* 1. Create ONE buffer:
* LVGL will draw the display's content here and writes it to your display
*
* 2. Create TWO buffer:
* LVGL will draw the display's content to a buffer and writes it your display.
* You should use DMA to write the buffer's content to the display.
* It will enable LVGL to draw the next part of the screen to the other buffer while
* the data is being sent form the first buffer. It makes rendering and flushing parallel.
*
* 3. Double buffering
* Set 2 screens sized buffers and set disp_drv.full_refresh = 1.
* This way LVGL will always provide the whole rendered screen in `flush_cb`
