+@par Example Description 
+
+This example provides a basic communication between USARTy and USARTz in 
+Half-Duplex mode using flags. USARTy and USARTz can be USART1 and USART2 or
+USART2 and USART3, depending on the STMicroelectronics EVAL board you are using.
+
+First, the USARTy sends data from TxBuffer1 buffer to USARTz using TXE flag.
+Data received using RXNE flag by USARTz is stored in RxBuffer2 then compared with
+the sent ones and the result of this comparison is stored in the "TransferStatus1" 
+variable.
+ 
+Then, the USARTz sends data from TxBuffer2 buffer to USARTy using 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 and USARTz configured as follow:
+  - BaudRate = 230400 baud  
+  - Word Length = 8 Bits
+  - One Stop Bit
+  - Even parity
+  - Hardware flow control disabled (RTS and CTS signals)
+  - Receive and transmit enabled

+@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), STM3210C-EVAL (Connectivity 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.
+    To select the STMicroelectronics evaluation board used to run the example, 
+    uncomment the corresponding line in USART/HalfDuplex/platform_config.h file
+
+  - STM32100E-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to USART2_Tx(PA.02).
+      
+  - STM32100B-EVAL Set-up   
+    - Connect USART1_Tx(PA.09) to USART2_Tx(PD.05).
+ 
+  - STM3210C-EVAL Set-up 
+    - Connect USART2 Tx pin (PD.05) to USART3 Tx pin (PC.10) and connect a 
+      pull-up resistor to this line (10K).  
+      @note In this case USART3 Tx pin is remapped by software.
+            Make sure that jumpers JP19 and JP18 are open.
+            
+  - STM3210E-EVAL Set-up 
+    - Connect USART1_Tx(PA.09) to USART2_Tx(PA.02) and connect a pull-up resistor to 
+      this line (10K).  
+
+  - STM3210B-EVAL Set-up   
+    - Connect USART1_Tx(PA.09) to USART2_Tx(PD.05) and connect a pull-up resistor to 
+      this line (10K). 
+  
+@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
