1．设计任务
本设计采用单片机为主控芯片，结合外围电路组成彩灯门的控制系统器，用来控制16个彩色的LED发光，实现彩色亮点的循环移动；通过软件编程实现各种各样的彩色亮点平面循环移动，该彩色控制器可以通过输入按钮、自动模式按钮和手动模式按钮来控制实现LED彩色十种灯光间的效果切换；还可以通过按钮暂停彩灯效果，使16个彩灯灯处于全亮的状态，再次按下相同按钮后继续之前的灯光闪烁效果。其中十种灯光效果分别是：顺时针流水灯、逆时针流水灯、交替闪烁、顺时针对角灯、逆时针对角灯、顺时针逐个点亮、顺时针逐个熄灭、逆时针逐个点亮、逆时针逐个熄灭、二进制加法。
2. 设计要求
2.1系统方案论证
根据设计任务，分析设计系统的组成，给出实现设计任务的几种方案，分析比较几种设计方案的优略，本着尽量以软件代替硬件，同时力求电路简单，工作可靠的原则，确定总体设计方案。
2.2系统硬件电路设计
根据系统设计方案进行软、硬件的分配，软、硬件设计分别进行。硬件设计包括单片机最小系统和扩展接口及配置，硬件结构在设计时要选择合适的元器件，硬件电路要简洁、工作可靠，需用Proteus绘制整个系统的电路仿真原理图。
2.3软件设计
根据该系统要求的功能进行软件设计，简述软件的功能，并根据每个模块的功能绘制软件流程图，根据流程图编写程序并汇编调试通过；列出软件清单，软件清单要求加以注释。
2.4 软硬件系统仿真
将编译后的程序软件加载到Proteus软件仿真的单片机ROM中，运行系统，实现软件程序对单片机系统的硬件电路的控制，并调试仿真结果，直至与设计任务相符。
