基于单片机的贪吃蛇游戏设计

利用三天假期把贪吃蛇游戏移植到了我的单片机开发板上，单片机是STC89C52只有8K的FLASH，本来想移植俄罗斯方块的但是移植编译之后大约有10K的空间。

下面是我拍的视频，优酷的链接：http://v.youku.com/v_show/id_XNjIxNjM2MzUy.html高手勿喷呐！

程序中使用的器件有：

　　（1）STC82C52配置有片内RAM512B，片内FLASH存储器 8KB，时钟为8MHz。

　　（2）2.4寸TFT彩屏，最大支持RGB565格式有65536种颜色。主控制器为ILI9325，程序中使用的是8位数据模式，所以运行比较慢。

　　（3）红外遥控器，采用的是HS0038芯片。红外协议是NEC协议，32位数据位，第一字节为标识码，第二字节为其反码，第三字节为数据位，第四字节为数据位反码。

　　下面是我的程序：

　　　　lcd.c是TFT液晶屏的驱动程序，key.c是红外芯片的驱动程序，snake.c是贪吃蛇游戏的程序。lcd.h,key.h以及snake.h是对应的头文件，里面有一部分与平台相关的定义

移植的时候只要做对应的修改即可。下面上一下游戏的界面：

下面开始贴源代码啦：

　　　　第一代码，lcd.c是TFT彩屏ILI9325的驱动程序。
