第一次自己写关于游戏的代码，学习到蛮多的。。。参考了很多资料，写了这个贪吃蛇。自己做着玩，所以代码没有精炼，没想得太多，只为了实现功能，所以代码比较冗长繁琐导致16K差不多用完了。板子上本来有20个灯，最初想法是想做流水效果点缀的，现在没办法只能以后再点上咯。。。代码和原理图附上。方便有想法要做的朋友-The first to write about the game code, learn to find many. . . A lot of information, wrote this snake. Doing their own play, so the code is not refined, thought too much, only to realize the function, so the code is relatively lengthy and cumbersome leading to almost 16K run out. Would have been on the board 20 lights, water effects initial idea was wanted embellishment, and now can not only point slightly later. . . Code and schematics attached. Easy to have an idea to do a friend. . .
