Description: This application describes how to use the annotation of high-density characteristics of STM32F103xx I2S codec using a external play audio files. I2S protocol is widely used from the microcontroller/DSP transfer audio data to the audio codec in order to play tunes (stored in memory), or win mode sound (from microphone). STM32F103xx use of high-density SPI peripheral devices I2S audio communication and implementation of specific functions for this communication.
