电子相册实现滑动解锁、JPG和BMP图片显示 用到的技巧有文件/系统IO函数，双向循环链表，目录检索和BMP，JPG图片显示的函数
源码在压缩包里
int main(int argc, char *argv[])
{
//初始化设备
Lcd_Init();
//显示锁屏界面
Show_bmp(0, 0,"lock.bmp");
usleep(1000);
//显示锁屏**
Show_bmp(100, 370,"**.bmp");
while(1)
{
//获取坐标
get_ts_xy();
Show_bmp(100,370,"frame.bmp");
usleep(10);
//触摸得到x轴变化的坐标，锁屏界面和**的图标交替刷新，达到**移动的效果
Show_bmp(a, 370,"**.bmp");
//判断滑块到达锁屏框最后，松手则跳出循环
if(ts_x2 >= 420&&ts_y2>370&&ts_y2<450)

break;
}
}
//在锁屏框最后显示解锁成功的**
Show_bmp(420, 370,&quot;unlock.bmp&quot;);
usleep(500000); //延时0.5秒
