MSP430 F5529 单片机 OLED 贪吃蛇 游戏

做了一块MSP430 F5529转接板看起来漂亮一点，没有就直接用杜邦线接线。

2. Snake game. Each time the snake eats a piece of food, its tail grows longer, making the game
   increasingly difficult. The user controls the direction of the snake’s head (up, down, left, or right), and
   the snake’s body follows. Food is randomly generated, and if the snake hits a wall or its own tail, the
   game ends. Keep score by how many turns or how much time the snake is alive。

//1  按键改变drection变量 从而改变方向
//2  按键驱动方向
//3  碰壁结束判断
//4  蛇头蛇尾显示
//5  改变蛇的坐标 蛇身体全部更新
//6  检查是否吃到了自己的身体
//7  检查是否吃到食物
