Hello, what is the possibility that you can help me set up or develop a code based on this, even if it is necessary to pay you, I need, based on the black pill card and the pcm5102, with the USB audio protocol to create a kind of crossover and digital graphic equalizer where it makes use of the DSP core integrated into the card and the control of the band gains is carried out through a graphic interface, either digital through an Android application or an analog interface, please I need your help.

Hi

The code to do all of that is already available if you use another ARM-based MCU namely an H7-based Teensy 4x - have you heard about it?

Recent STM examples seems to move away from audio DSP's

Please see the Teensy Audio System Design Tool and the Teensy forum

If you post the following on the Teensy forum you will get a good reaction from the members there:

Hello, I am new to the Teensy world and before I purchase any, I would like to know if what I need already exist or is possible?
