基于单片机的光立方设计
【摘要】本设计制作了一个8*8*8的LED光立方,这个作品不仅能够显示静态的画面,还能够通过延时程序的控制产生立体动态的效果,可以广泛的运用在媒体的信息传递,而且具有很好的装饰效果,是未来媒体传播的一个发展趋势,具有很好的发展前景。
在此次设计光立方核心控制器选择的是单片机STC12C5A60S2,选择74LS573锁存器扩展I/O口,完成硬件电路设计。显示采用的是扫描显示方式,根据相应的数据表分别选通所需要的片选列信号,然后再根据送到P0口的列数据给到74HC573进行锁存。单片机通过控制P1口的输出状态,来驱动ULN2803,从而控制每一层的选通状态。在软件设计的过程中,运用模块化的思想,分块设计,相对独立的模块,增强了系统的可塑性。

The design of Light Cube Based on The Microcontroller
【Abstract】This design produced a three-dimensional pattern of the LED light cube. This works not only display static images, but also capable of producing three-dimensional dynamic effect by controlling of the delay proceedings .It can be widely used in information transmission media, but also has very good decorative effect. Besides it is a trend of the future development of the media, it has good prospects for development
In the design of light cube core controller MCU STC12C5A60S2 is selected,74LS573 latch expansion I/O port completion of the hardware circuit design. Display uses a scanning way, according to the corresponding data table respectively gating need choose column signal, and then according to the column data on to P0 mouth to 74 hc573 latches. Single-chip microcomputer by controlling the output state of the P1 mouth to driven ULN2803, to control the gate of the each layer.In the process of software design, based on the idea of modularization, block design, independent modules, to enhance the plasticity of the system.
