继上次74HC595显示自己想要的图案后，如果把一个芯片控制的64个灯当作一层，那么把八个芯片叠加在一起就可以达到立体显示的效果。
由于一个芯片占据3个引脚，八个只需要24个引脚，剩下引脚可以加入中断添加蓝牙、遥控、按键等功能原理可行，那么，开干。。。。。。
由于某些原因，在某宝上买了散件制作了一个光立方（制作花了我小一个月）。
?
?
?单片机型号不同但原理相同，代码很长放在文末，下面是效果展示
?另外这次玩光立方的时候遇到了传输数据的问题，USB接口不能传输数据，查阅资料后发现需要一个USB转TTL的模块
?这个模块既可以用来给各种单片机下载代码，也可以用来给光立方上位机进行演示，模块虽小，功能俱全。当然使用方法也很简单，只需要查看芯片原理图找到对应VCC,GND,TXD,RXD连接就行
另外用到的串口驱动还是学习单片机时使用的老朋友CH340。
最后额外声明一下，下面的代码是商家给的，仅供学习参考（商家：上升沿）
