硬件使用的是完全除了LCD_BL引脚，其他均兼容STM32F407-ATK-EXPLORER板子，LCD采用的是3.2寸320*240分辨率的电阻屏
问题：LCD驱动测试完全正常，使用littlevgl2rtt软件包无法刷新屏幕和显示
最后调试和查找资料发现，由于我是没有使用rt_device_graphic_info的framebuffer，所以会使用到刷新函数是使用lcd_flush，与lcd_fb_flush对比最后缺少lv_disp_flush_ready函数进行通知刷新，导致屏幕无法刷新，加上之后就可以显示正常了
还有一点建议，该软件包是使用第一种缓冲区的方式进行显示的，刷新较慢，建议可以通过选择来支持三种的缓存方式
