This application note describes how to use the high-density STM32F103xx I?S feature to play audio files using an external codec.

The I?S protocol is widely used to transfer audio data from a microcontroller/DSP to an audio codec in order to play melodies (stored in a memory) or, to capture analog sound (from a microphone). The high-density STM32F103xx allows I?S audio communications using the SPI peripheral, and implements specific functionalities for this communications mode.
