基于stm32f103VE的贪吃蛇小游戏源程序

ID:583948 · 发表于 2019-7-14 16:09

按键控制，液晶屏显示

外接按键原理图，接单片机引脚PC10,PC11

开机动画

游戏开始界面

本帖需要重新编辑补全电路原理图,源码,详细说明与图片即可获得100+黑币(帖子下方有编辑按钮)

ID:282095 · 发表于 2019-7-15 09:16

请问硬件部分和系统架构呢

ID:583948 · 发表于 2019-7-15 11:43

外接了两个按键，PC10,PC11.

ID:669130 · 发表于 2019-12-31 22:04

这个是mini的
