+
+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.
+
+
+Directory contents
+==================
+stm32f10x_conf.h     Library Configuration file
+stm32f10x_it.c       Interrupt handlers
+stm32f10x_it.h       Header for stm32f10x_it.c
+main.c               Main program
+
+
+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

+
+Example description
+===================
+This example provides a description of how to set a communication between two
+SPIs in I2S mode, and how to switch between SPI and I2S modes, performing a 
+transfer from Master to Slave in I2S modes then a transfer from master to slave 
+in SPI mode and finally a transfer from Slave to Master in I2S mode.
+
+I2S2 is configured as master transmitter and I2S3 as slave reciever and both are 
+in Phillips standard configuration with 16bit data size in 32bit packet length 
+and 48KHz audio frequnecy.
+
+In the first phase, the master I2S2 starts the I2S2_Buffer_Tx transfer while the 
+slave I2S3 receieves and loads the values in I2S3_Buffer_Rx. 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 preripherals are configured in SPI modes (simplex 
+communication) and SPI2_Buffer_Tx transfer is performed in simplex mode from SPI2 to
+SPI3.Once the transfer is completed a comparison is done and TransferStatus2 gives 
+the data transfer status where it is PASSED if transmitted and received data are 
+the same otherwise it is FAILED.
+As the master/slave mode is managed by software (the master is the clock (CK and WS) 
+generator), this allows to I2S2 to become slave transmitter and I2S3 to become master 
+receiver whithout hardware modification. 
+
+In the third step, the slave I2S2 prepares the first data to be sent before the 
+master is enabled. Once the master is enabled, the clocks are released from the 
+master and the data are released on the slave. Once the transfer is completed 
+a comparison is done and TransferStatus3 gives the data transfer status where it 
+is PASSED if transmitted and received data are the same otherwise it is FAILED.

+Directory contents
+==================
+stm32f10x_conf.h     Library Configuration file
+stm32f10x_it.c       Interrupt handlers
+stm32f10x_it.h       Header for stm32f10x_it.c
+main.c               Main program
+
+
+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
