基于CPLD的音乐LED点阵控制器

The Music LED Point Lattice Controller Based on CPLD

设计的音乐LED点阵控制器集音乐演奏及LED点阵显示为一体,硬件部分由ALTERA公司的EPM1270CPLD、LED点阵控制电路组成,LED点阵控制芯片为74HC595。软件部分由音乐控制模块、点阵显示电路模块组成。CPLD产生的不同音乐节拍可以使能不同的74HC595芯片,使LED点阵随音乐节拍显示不同的图案,能收到良好的视听效果,可以应用到广场灯光布置、舞厅灯光布置、家庭灯光布置等场合。

Music performance and LED dot matrix display are combined by designing music LED dot matrix controller. The hardware includes the EPM1270 made by Altera Company and the control circuit of LED point lattice. The 74HC595 is selected to control the LED. The software has the component of music controller and display programmer. The music clock produced by CPLD can use different 74HC595 and the different patterns are displayed. It can achieve a good audio--visual effect. It can be applied to the public square, dancing--room and home.
