《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STC32G12K128-Beta。
有两个版本自制独立按键版本和矩阵按键模块版本。
本文代码对应的是矩阵按键模块版本。 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自制独立按键版本
2矩阵按键模块版本 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8X8彩色点阵屏WS2812B的显示问题。
一个灯图片中白色正方形里面有三个LED分别是红、绿、蓝白色正方形中其实也集成了WS2812B芯片一个芯片可以存储3个字节Byte的数据接收到3个字节的数据后会把后面接收到的数据传给下一个灯的WS2812B芯片。一个字节控制一种颜色的LED即一个灯需要用24位Bit控制所以一个灯的颜色变化种类有22416777216种。
如何发送0和1呢类似DS18B20的数据发送通过高电平的时长来确定发送的是0还是1“0”的高电平时长较短“1”的高电平时长较长具体的时序图可以参考一下其他博主的文章。经过测试高低电平的时长要求不算严格但是需要注意的是如果不注意定时器中断函数打断的影响屏幕会出现“花屏”的情况即一个字节才发送一半就被定时器中断函数打断的话原来要发送的数据就改变了。如果以一个字节为单位发送一个字节前关闭总中断EA0发送完一个字节后再开启中断EA1这样显示就不会出现问题这样即不影响显示也不影响定时器的运行但是要注意定时器中断函数代码的执行时间不能太长太长的话相当于发送了重置RESET指令给WS2812B芯片屏幕会乱闪。
