摘要
研究一种基于STC12C5A60S2增强型单片机作为主控芯片的光立方音频谱显示方案。以STC单片机为核心,以74HC573为锁存器,采用与点阵相同的动态扫描驱动显示原理,实现LED的光立方显示。同时利用音频输入,结合FFT算法,实现音频谱的光立方显示,给人以良好的视觉和听觉感受。
A 3D light cube system of audio spectrum display based on MCU STC12C5A60S2 controller was presented. With STC single chip as the core,LED light cube display of audio spectrum was designed using latch 74HC573 and dynamic scanning in the same way as dots LED screening.The platform provides better display of audio spectrum combined with audio input and FFT algorithm,which can offer a good visual and auditory effect.
