I2S Audio Codec Interface with STM32H743

Interfacing an audio codec with a microcontroller is a common task in DSP and audio-related projects.

This post will summarize the basics steps that have to be taken in order to make an audio codec work with an STM32 microcontroller.

Most of the principles exposed here can be applied to any audio codec which uses i2s protocol and control registers for hardware configuration.
