This example describes how to play audio using the I2S module:
In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 clock is the 2 frequency division of the Main clock, APB2 clock is from Main clock.
In this example, the ES8316 chip is used to play the audio. When this example is run, the relevant information is printed out through UART1. When the audio plays, you will hear "left channel" in the left channel and "right channel" in the right channel. The audio sampling frequency in this routine is 22050Hz.
In order to make the program work, you must do the following :
