毕业论文-8×8×8个LED 灯组成的真实3D立方体显示器设计.doc

摘要
光立方是一个长、宽、高由8×8×8 个LED 灯组成的真实3D 立方体显示器。其最大的特点,就是带给观赏者立体的超酷的3D视觉体验。因此各大网站也充斥着各种各样的光立方版本。
但是这各种版本的光立方的制作方法都很复杂,而且成本也很高,而本设计与之相比则制作简单精美,成本低廉。
为保证光立方精美的外形,本设计还提供了一种光立方的制作模板,以确保将动手能力导致的美观差异降到最低。
为降低其成本,本设计采用了STC12C5A60S2单片机,这种单片机自带有A/D转换模块;使用的锁存器是常用的SN74HC573。这样可以保证在降低制作成本的情况下,毫不影响作品的美观;再加上显示效果极佳的高亮雾面的蓝色方形LED,硬件电路无需添加额外的驱动和上拉电阻,即可实现其强大的功能:除了能显示3D 图形,还可以支持多级亮度和速度调整,允许用户自拓展音频显示功能,就像音乐显示器一样。用户还可以在不改动硬件电路的情况下设计出自己喜欢的的自定义图形。这些充分体现了制作成本低、显示效果好、功能完善的特点。
最后,经过软硬件调试,解决了一些硬件电路短路,程序报错的问题,完美地实现了多种图形动态显示,流畅的图形变换和音频显示的多种功能。

ABSTRACT
Light-cube is a long, wide, high posed of 8 x 8 x 8 leds true 3 d volumetric display. Its biggest characteristic, is to bring the viewer stereo cool 3 d visual experience. So each big web site is filled with all kinds of cubic light version.
But all versions of this light cubic method is plex, and the cost is also high, pared with this design is beautifully simple and low cost.
In order to ensure the exquisite cubic shape, this design also provides a light cube production template, to ensure that the ability to appearance difference to a minimum.
To reduce its cost, this design USES STC12C5A60S2 MCU, the MCU built-in A/D conversion module; Use the latch is SN74HC573 mon use. So that in the case of lower production costs, not effect the beauty of the works; Plus showed excellent results highlighted square LED fog below in blue, don't need to add additional hardware circuit drive pull up resistance, and its powerful functions can be realized: in addition to display 3 d graphics, can support multiple levels of brightness and speed adjustment, allows the user to expand the audio display function, like music display. Users can also in the case of do not change the hardware circuit design their own custom graphics. These fully reflect the production of low cost, good effect of display, the characteristics of the function is perfect.
Finally, after the hardware and software debugging, solve some of the short circuit hardware
