| 摘 要： | 文章介绍了一种音乐LED彩灯控制系统,系统由软件与硬件两部分组成,硬件部分由CPLD EPM1270、LED彩灯控制电路、数码显示电路、按键电路和扬声器电路组成,LED彩灯控制芯片为CD4017.软件部分由音乐产生及控制模块及数码显示模块组成.CPLD产生的不同音乐节拍可以使能不同的CD4017芯片,使组成某种图案的不同颜色彩灯随音乐节拍闪烁,具有很好的观赏性.系统具有硬件电路简单、体积小、功耗低、可靠性高,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变换LED彩灯的显示花样.

| Abstract: | A musical LED lantern control system is pnesented,the system consists of two parts,software and hardware.The hardware concludes the CPLDEPM1270,LED lights control circuit,the digital display circuit,key circuit and speaker circuit,and LED lights controlling chip is CD4017.Software concludes the music produce-control module and digital display module.Different beat of the music is produced by CPLD,it can enable different CD4017 chip,and the different color lantern of the composition flashing with the music.The hardware circuit of the system has particular in simple,small size,low power consumption,high reliability,and particularly,we can easily change the pattern of the LED lights through modifyign the software,but not the hardware. |
