-Example description
-===================
-This example provides a description of how to set a communication between two
-SPIs in I2S mode using interrupts and performing a transfer from Master to Slave.
-
-In the first step, I2S2 is configured as master transmitter and I2S3 as slave
-reciever and both are in Phillips standard configuration with 16bit extended to
-32 bit data packet and 48KHz audio frequnecy.
-
-The I2S2 transmit interrupt and the I2S3 receive interrupt are both enabled. And
-in these interrupts subroutines, the I2S2_Buffer_Tx is transmitted and the received
-values are loaded in the I2S3_Buffer_Rx buffer. Only the significant 16 MSBs are
-sent and received, while the 32 packet remaining 16 LSBs are filled with 0 values
-and don't generate any interrupt.
-
-Once the transfer is completed a comparison is done and TransferStatus1 gives the
-data transfer status where it is PASSED if transmitted and received data are the
-same otherwise it is FAILED.
-
-In the second step both peripherals are configured in I2S Phillips standard 24 bits
-data length in 32 bits packets and 16KHz audio frequency. The interrupts are
-enabled and the transfer is performed from the I2S2 master to the I2S3 slave.
-The 24 bits are transmited then the 8 remaining LSBs are filled automatically
-with 0 values.
-
-Once the transfer is completed a comparison is done (on the 24 MSBs only, the 8
-LSBs are replaced by 0) and TransferStatus2 gives the data transfer status where
-it is PASSED if transmitted and received data are the same otherwise it is FAILED.

-==================

-stm32f10x_it.c Interrupt handlers
-stm32f10x_it.h Header for stm32f10x_it.c

-
-Hardware environment
-====================
-This example runs on STMicroelectronics STM3210E-EVAL evaluation board and can be
-easily tailored to any other hardware.
-
- - Connect I2S2 WS (PB.12) pin to I2S3 WS (PA.15) pin
- - Connect I2S2 CK (PB.13) pin to I2S3 CK (PB.03) pin
- - Connect I2S2 SD (PB.15) pin to I2S3 SD (PB.05) pin
-
-Since some SPI3/I2S3 pins are shared with JTAG pins (SPI3_NSS/I2S3_WS with JTDI
-and SPI3_SCK/I2S3_CK with JTDO), they are not controlled by the I/O controller
-and are reserved for JTAG usage (after each Reset).
-For this purpose prior to configure the SPI3/I2S3 pins, the user has to disable
-the JTAG and use the SWD interface (when debugging the application), or disable
-both JTAG/SWD interfaces (for standalone application).
-
-
-How to use it
-=============
-In order to make the program work, you must do the following:
-- Create a project and setup all your toolchain's start-up files
-- Compile the directory content files and required Library files:
- + stm32f10x_lib.c
- + stm32f10x_spi.c
- + stm32f10x_rcc.c
- + stm32f10x_gpio.c
- + stm32f10x_nvic.c
- + stm32f10x_flash.c
-
-- Link all compiled files and load your image into target memory
-- Run the example
