功能

  1. 恩智浦 Gui Guider + Platformio + ESP32S3 移植测试
  2. 以及 LVGL 优化

UI 移植

1.设计 UI 并导出代码

2.MYUI 文件下添加 library.json

    }
  }

3.将 LV_VER_RES_MAX 替换为 LV_VER_RES，LV_HOR_RES_MAX 替换为 LV_HOR_RES

优化

参考博主重回桃花源的《LVGL显示优化—基本优化》

1.修改帧率

LVGL是有一个帧率刷新周期的宏定义，在lv_conf.h里。LVGL会通过LVGL内部的tick，定时去刷屏幕，也就是说该宏定义限定了LVGL刷屏帧率的上限，默认满帧33帧。

1
#define LV_DISP_DEF_REFR_PERIOD 30 /[ms]/

改成10ms刷新一次，满帧100帧。顺手再把输入设备读取周期也改成10ms。

/*Default display refresh period. LVG will redraw changed areas with this period time*/
#define LV_DISP_DEF_REFR_PERIOD 10      /*[ms]*/
/*Input device read period in milliseconds*/
#define LV_INDEV_DEF_READ_PERIOD 10     /*[ms]*/

最终效果
