《贪吃蛇》一款经典的、怀旧的小游戏单片机入门必写程序。
以《贪吃蛇》为载体熟悉各种屏幕的使用。
所用单片机STC89C52RC
有两个版本普中开发板矩阵按键版本和最小系统板自制独立按键版本。
本文代码对应的是最小系统板自制独立按键版本。 效果查看/操作演示B站搜索“甘腾胜”或“gantengsheng”查看。 源代码下载B站对应视频的简介有工程文件下载链接。 一、效果展示
1普中开发板矩阵按键版本
2最小系统板自制独立按键版本
二、原理分析
游戏原理可以参考以下这篇文章 基于51单片机和8X8LED点阵屏板载74HC595驱动的普中开发板矩阵按键控制的小游戏《贪吃蛇》
这里主要说一下显示问题。
此16X16点阵屏模块采用2个74HC138和2个74HC595来驱动显示。74HC138选通某一行送入2个字节数据到2个74HC595来控制这一行的显示。
芯片MAX7219内含自动扫描电路驱动的点阵屏不会占用单片机的资源。
此点阵屏模块需要利用单片机的定时器来进行扫描显示定时的时间太短会频繁进中断函数影响主函数的代码的执行定时的时间太长点阵屏又会出现闪烁的现象总共有16行每个LED灯接通的占空比为1/16。所以需要找到一个平衡既不会使点阵屏出现明显的闪烁又不会影响主函数代码的执行。经过摸索这个定时的时间大约是1ms多效果不好的话可以继续调一下。
三、各模块代码

}总结
这个点阵屏模块比较占用单片机的资源如果用速度较快的单片机则影响不大如果是用89系列的单片机会感觉影响比较大建议用MAX7219驱动的点阵屏很好用。
