Music Spectrum Display System Based on MCU

Abstract:

Analysis of signal from the frequency analysis of spectrum, which is widely used in voice processing, image processing, digital audio, seismic exploration. With the FFT algorithm, provides an effective solution for real-time processing of frequency domain analysis. Based on STC12C5A60S2 microcontroller to complete realization of music spectrum display system development, which introduces the STC12C5A60S2 chip, 32*64LED dot matrix display principle, 74LS595 and 74LS164 chip using the method. On this basis, the completion of the system's hardware and software design, implementation STC12C5A60S2 microcontroller based music spectrum display system, its structure is simple, easy to use, and you can use STC12C5A60S2 MCU data processing capabilities of the sound signal spectrum analysis and display.
