摘　　要：设计了一种基于可编程逻辑器件CPLD芯片的32路彩灯控制器,该彩灯控制器用VHDL硬件描述语言设计其核心部件,再配以适当的外围电路构成,上电后,彩灯系统无需外加输入信号,能自动循环演示十六种花型,彩灯明暗变换节拍为0.25秒和0.5秒,快慢两种节拍自动交替运行。该系统较以前的传统设计具有硬件电路简单、体积小、功耗低、可靠性高、花型种类多等特点,特别是可以在不修改硬件电路的基础上,仅通过更改软件就可实现任意修改花型的编程控制方案。该彩灯控制器适合大型灯会、舞台灯光控制、广场灯光控制场所。A sorts of 32 routs colorful lamps controller is designed based on CPLD,the controller is formed with core,which designed with VHDL,and propriety periphery circuit. The colorful lamps system need not more input signal and can cycle automatically to de-mo 16 kinds flower types when the power is on,the switch times of colorful lamps’ light and shade are 0.25 second and 0.5 sec-ond,the fast and slow times is automatic exchange. The system has some characteristics,which included hardware circuit is simple,bulk ...
