+@par Example Description 
+
+This example provides a basic communication between USARTy (Synchronous mode) 
+and SPIy using flags. USARTy and SPIy can be USART1 and SPI1 or USART2 and SPI3,
+depending on the STMicroelectronics EVAL board you are using.
+
+First, the USARTy sends data from TxBuffer1 buffer to SPIy using USARTy TXE flag.
+Data received, using RXNE flag, by SPIy is stored in RxBuffer2 then compared with
+the sent ones and the result of this comparison is stored in the "TransferStatus1" 
+variable.
+ 
+Then, the SPIy sends data from TxBuffer2 buffer to USARTy using SPIy TXE flag.
+Data received, using RXNE flag, by USARTy is stored in RxBuffer1 then compared with
+the sent ones and the result of this comparison is stored in the "TransferStatus2" 
+variable.
+
+USARTy configured as follow:
+  - BaudRate = 115200 baud  
+  - Word Length = 8 Bits
+  - One Stop Bit
+  - No parity
+  - Hardware flow control disabled (RTS and CTS signals)
+  - Receive and transmit enabled
+  - USART Clock enabled
+  - USART CPOL: Clock is active high
+  - USART CPHA: Data is captured on the second edge 
+  - USART LastBit: The clock pulse of the last data bit is output to the SCLK pin
+
+SPIy configured as follow:
+  - Direction = 2 Lines FullDuplex
+  - Mode = Slave Mode
+  - DataSize = 8 Bits
+  - CPOL = Clock is active high
+  - CPHA = Data is captured on the second edge 
+  - NSS = NSS Software
+  - First Bit = First Bit is the LSB

+@par Hardware and Software environment 
+
+  - This example runs on STM32F10x Connectivity line, High-Density, High-Density 
+    Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density 
+    and Low-Density Value line Devices.
+  
+  - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density 
+    Value line), STM32100B-EVAL (Medium-Density Value line), STM3210E-EVAL 
+    (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) evaluation 
+    boards and can be easily tailored to any other supported device and development 
+    board.
+    This example can't be tested with STM3210C-EVAL (Connectivity Line) evaluation
+    board since the USART CK pins are already used by other on-board modules.
+    To select the STMicroelectronics evaluation board used to run the example, 
+    uncomment the corresponding line in USART/Synchronous/platform_config.h file
+
+  - STM32100E-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to SPI1_MOSI(PA.07), USART1_Rx(PA.10) to 
+      SPI1_MISO(PA.06) and USART1_CK(PA.08) to SPI1_SCK(PA.05).  
+      
+  - STM32100B-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to SPI1_MOSI(PA.07), USART1_Rx(PA.10) to 
+      SPI1_MISO(PA.06) and USART1_CK(PA.08) to SPI1_SCK(PA.05).      
+
+  - STM3210E-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to SPI1_MOSI(PA.07), USART1_Rx(PA.10) to 
+      SPI1_MISO(PA.06) and USART1_CK(PA.08) to SPI1_SCK(PA.05).
+
+  - STM3210B-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to SPI1_MOSI(PA.07), USART1_Rx(PA.10) to 
+      SPI1_MISO(PA.06) and USART1_CK(PA.08) to SPI1_SCK(PA.05).

+@par How to use it ? 
+
+In order to make the program work, you must do the following :
+ - Copy all source files from this example folder to the template folder under
+   Project\STM32F10x_StdPeriph_Template
+ - Open your preferred toolchain 
+ - Rebuild all files and load your image into target memory
+ - Run the example
