我的娱乐系统世界
这是第一次写博客，保存最近做的一次项目，代码有点长。（可能会有bug，不喜勿喷，纯粹用于个人纪录）。
时间：2020年7月31日
内容：Linux，6818开发板，触摸屏，花样展示图片（轮播，百叶窗，缩放等），视频，音频，2048小游戏
解释都在代码里
//新增音乐相册（可以在相册里点击进入）
//将相册目录改成了缩略图，可点击跳转对应图片。

2048 右移逻辑，先找到第一个不为空格的数a[ i ][ j ]，然后用另一个数组，与a[i][j]对比各种情况；
eg：当a[i][j]与a[i][k]相等时，a【i】【k】= a【i】【j】，a【i】【j】= 0；若不相等，则a【i】【k-1】= a【i】【j】;还有各种细节，可以看代码，上下左右都是同一个逻辑。
