LVGL(也可以直接裸跑)实现的数字变换动画

想用ESP32做一个时钟,但是如果数字变化只是普通的突然从0变成1就觉得很没新意,感觉用51 MCU也能实现。之前看到CSDN上有一个点阵钟实现了一个简易的数字变换效果【链接: https://img-blog.csdnimg.cn/20181101232344268.gif 】,本小白又觉得都已经用上点阵了,没必要还把数字显示成数码管的样子,有点掉价。所以就简单用QT写了一个简单的数字动画设计辅助的软件,在上面用20个前后相连的点表示数字,生成0到9的数字图像的坐标数组,用LVGL的lv_anim实现数字间的变换。其实代码怎么写的不重要,用不用LVGL也不重要,主要是最后生成的0-9的坐标数组,我就直接贴在下面啦。显示效果在附件视频,第一次发帖不知道怎么附视频

0-9坐标数组:

const uint16_t num_dot[11][2*DOT_NUM]={
    { 0x00bf,0x0001,0x0025,0x0001,0x0008,0x001e,0x0000,0x0046,0x0000,0x02ff,0x0017,0x031f,0x002d,0x032f,0x0160,0x032f,0x017d,0x0321,0x0191,0x0304,0x0191,0x0025,0x0179,0x000b,0x0150,0x0000,0x00d3,0x0000,0x00d3,0x0069,0x011a,0x0069,0x011a,0x02c8,0x0079,0x02c8,0x0079,0x0067,0x00bf,0x0067 },

};//0-9坐标表,每一维中的数据一次是20个点的横纵坐标排列(X1,Y1,X2,Y2.....),最后一维所有的点集中在中间,是归位





为了方便ESP32+LVGL用户即食,我写了一个库,可以创建任意多个(当然前提是内存要够)独立的数字,库在附件的压缩文件

Re: LVGL(也可以直接裸跑)实现的数字变换动画

效果挺酷,楼主能讲解下实现原理吗?能否再实现个翻页钟效果或数字上下滑动的效果?
