&par Example Description

This example describes how to use I2S peripheral.
by making a communication between the I2S2 and the I2S3.
If communication success, LED3  will turn off, otherwise LED3 will turn on.

&par Hardware Description

    Connect I2S2 and I2S3 pins as follows:
    I2S2 WS    (PB12)   to  I2S3 WS   (PA15)
    I2S2 CK    (PB13)   to  I2S3 CK   (PB3)
    I2S2 SD    (PB15)   to  I2S3 SD   (PB5)

  - USART1 configured as follow:
  - BaudRate = 115200
  - Word Length = USART_WordLength_8b
  - Stop Bit = USART_StopBits_1
  - Parity = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
