f1c200(板子widora tiny200-r3)的lvgl7.11.0移植例程(屏是800x480的电容屏)

上传到这里做个笔记^^

重新编辑原因：原来的LVGL刷屏速度太慢了，下午调试发现把lv_tick_inc(5)新开一线程更新，速度上来了，重新上传修改后的代码

源码是：lvgl7110_f1c_demo.7z，自己下载解压

1. 改lvgl及makefile
（1）lvgl
东西都是现成了，下了当前最新的lvgl 7.11.0版本，
主要改了lv_conf.h，lv_drv_conf.h，lv_ex_conf.h三个配置文件，以及main函数修改了一下。
具体忘记改哪些了，都是make的时候，哪里报错就改哪里的，直接看我的例程源文件

（2）
参考网上把makefile文件改了一下，主要是把交叉编译链的目录改成自己的目录就可以了，比如我的是
CC = /home/myway/f1c200/buildroot-tiny200/output/host/bin/arm-buildroot-linux-gnueabi-gcc-8.4.0
然后就可以make 生成执行文件 lvgl_7110_demo

2. 运行
将编译出来的lvgl_7110_demo放在tiny200-r3的文件系统，比如我的放在root文件夹下，运行如下
# pwd
/root
# ls
lvgl_7110_demo
# chmod 777 lvgl_7110_demo
# ./lvgl_7110_demo 3
lvgl version:7.11.0
demo num:3
The framebuffer device was opened successfully.
800x480, 32bpp
The framebuffer device was mapped to memory successfully.

总共51个demo,运行第几个demo就加相应的数字，如运行第3个就是
./lvgl_7110_demo 3

demo数字对应的数字如下，参考main函数：

	switch(demo_num)
	{
		case 0:
		case 1: lv_demo_widgets(); break;
		case 2: lv_demo_music(); break;
		case 3: lv_demo_printer(); break;
