2.设计按键电路，该按键实现功能选择及操控光标的定位移动；
该部分主要实现打击等功能；
该部分主要实现一键开关机及复位，设置为短按开机长按关机，该电路中需要特别注意的是必须放置D1二极管。
该部分电路为一键开关机硬件电路的设计
3.设计电池供电电路。
此电路为电池充电电路，在未满情况下红灯指示，已满状态下绿灯指示，结束充电。
该部分为电池电压采集电路，该电路中的Q9主要是为了防止关机存在耗电现象。
4.设计音频输出电路，不但可以耳机输出，还可以外放游戏声音，通过软件设置声音的开启与关闭。
5.设计存储电路，存储每次操作后的数据，保证再次上电时之前设计的数据依然有效。
6.该部分电路主要实现震动功能。
总结：在本次游戏机设计中，遇到了很多的问题，通过网上查找资料及与群内部人员交流解决部分问题；在此次设计中，学习到了很多，提升了自己解决问题以及独立思考的能力；学会更多的是，对该主控芯片的应用。以立创梁山派开发板为核心设计外围电路，编写程序，实现所有功能。
