+
+@par Example Description 
+
+This example provides a basic communication between USARTy and USARTz using 
+interrupts. USARTy and USARTz can be USART1 and USART2 or USART2 and USART3, 
+depending on the STMicroelectronics EVAL board you are using.
+
+USARTz sends TxBuffer2 to USARTy which sends TxBuffer1 to USARTz. The data received 
+by USARTy and USARTz are stored respectively in RxBuffer1 and RxBuffer2. The data
+transfer is managed in USARTy_IRQHandler and USARTz_IRQHandler in stm32f10x_it.c file.
+
+USARTy and USARTz configured as follow:
+  - BaudRate = 9600 baud  
+  - Word Length = 8 Bits
+  - One Stop Bit
+  - No parity
+  - Hardware flow control disabled (RTS and CTS signals)
+  - Receive and transmit enabled       
+
+        
+@par Directory contents 
+
+  - USART/Interrupt/platform_config.h    Evaluation board specific configuration file
+  - USART/Interrupt/stm32f10x_conf.h     Library Configuration file
+  - USART/Interrupt/stm32f10x_it.h       Interrupt handlers header file
+  - USART/Interrupt/stm32f10x_it.c       Interrupt handlers
+  - USART/Interrupt/main.c               Main program
+  - USART/Interrupt/system_stm32f10x.c   STM32F10x system source file
+
+@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/Interrupt/platform_config.h file
+
+  - STM32100E-EVAL Set-up 
+    - Connect a null-modem female/female RS232 cable between CN10 (USART1) and 
+      CN5 (USART2).
+      @note Make sure that jumper JP5 is not open.
+
+  - STM32100B-EVAL Set-up
+    - Connect a null-modem female/female RS232 cable between CN10 (USART1) and 
+      CN9 (USART2).
+      @note In this case USART2 Tx and Rx pins are remapped by software on PD.05
+            and PD.06 respectively. 
+            
+  - STM3210C-EVAL Set-up 
+    - Connect USART2 Tx pin (PD.05) to USART3 Rx pin (PC.11)
+    - Connect USART2 Rx pin (PD.06) to USART3 Tx pin	(PC.10)
+      @note In this case USART3 Tx and Rx pins are remapped by software.
+            Make sure that jumpers JP19 and JP18 are open.
+              
+  - STM3210E-EVAL Set-up 
+    - Connect a null-modem female/female RS232 cable between CN12 (USART1) and 
+      CN8 (USART2).
+    
+  - STM3210B-EVAL Set-up
+    - Connect a null-modem female/female RS232 cable between CN6 (USART1) and 
+      CN5 (USART2).
+      - In this case USART2 Tx and Rx pins are remapped by software on PD.05
+        and PD.06 respectively. 
+  
+@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 
+
+@note
+ - Low-density Value line devices are STM32F100xx microcontrollers where the 
+   Flash memory density ranges between 16 and 32 Kbytes.
+ - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
+ - Medium-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 64 and 128 Kbytes.  
+ - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
+ - High-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes. 
+ - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes. 
+ - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 512 and 1024 Kbytes.
+ - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
