摘　　要：论述了一个基于FPGA的数控调速音乐彩灯控制系统的设计方案,系统由软件与硬件两部分组成,硬件部分由FPGA EP1C12Q240C8,LED彩灯控制电路、扬声器电路组成。软件部分由音乐产生模块、点阵译码模块和速度控制模块组成。通过系统仿真和测试,系统实现音乐播放的同时彩灯随音乐节拍以4种速度8种花样闪烁,可以有效解决彩灯的调速、花样变化、音乐播放等功能,广泛适用于节日彩灯、广告彩灯、工艺彩灯等诸多场合。系统具有硬件电路简单、体积小、功耗低、可靠性高等特点,特别是可以不改变硬件电路仅需修改软件程序就可变换彩灯点阵的显示花样和播放歌曲。An FPGA-based digital control adjustable speed system for music lantern design is discussed, the system is com- posed of software and hardware parts. The hardware part contains the FPGA EP1 C12Q24OC8, LED lights control circuit and the speaker circuit. The software part contains music generation module, lattice decoding module and speed control module. Through simulation and test, the system achieve music player and lattice blinking with the music beat in four speed and eight flash mood. System design can effectively solve the lantern governor, patterns change, music player and other functions, can be widely applied to holiday lights, advertising lights, craft lights and many other occasions. The system is provided with sim- ple hardware circuit, small size, low power consumption, high reliability, in particularly not modify the hardware circuit only change the software program can transform lantern lattice display patterns and play song.
