In the audio input to the collected signals, with the AD, how to deal with the back of the lattice led display

CodePudding user response:

Through the IO port output control signals.

CodePudding user response:

51 handle spectrum?
The speed is not enough, you can study the digital signal processing (DSP)/FFT

CodePudding user response:

Using FFT, online file have an existing algorithm, then the data is processed into a spectrum, in led dot matrix display on line,

CodePudding user response:

Do you want to make a spectrum display, histogram shows bai after FFT

CodePudding user response:

There is a software you can go to search the transcoder is music
