+Example description
+===================
+This example shows how to retarget the C library printf function to the USART.
+This implementation output the printf message on the Hyperterminal using USARTx.
+USARTx can be USART1, USART2, USART3, UART4 or UART5; to select the USART
+interface to be used uncomment the '#define USE_USARTx' line in 'platform_config.h'
+file.
+
+The USARTx is 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
+
+
+Directory contents
+==================
+platform_config.h Evaluation board specific configuration file
+stm32f10x_conf.h Library Configuration file
+stm32f10x_it.h Interrupt handlers header file
+stm32f10x_it.c Interrupt handlers
+main.c Main program
+
+
+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
+boards and can be easily tailored to any other hardware.
+To select the STMicroelectronics evaluation board used to run the example, uncomment
+the corresponding line in platform_config.h file.
+
+ + The USARTx signals (Rx, Tx) must be connected to a DB9 connector using a RS232
+ transceiver.
+
+ + Connect a null-modem female/female RS232 cable between the DB9 connector
+ and PC serial port.
+
+ + STM3210B-EVAL
+ - Connect a null-modem female/female RS232 cable between the DB9 connector
+ (CN6 for USART1, CN5 for USART2 in the STM3210B-EVAL board)
+ and PC serial port.
+
+ + STM3210E-EVAL
+ - Connect a null-modem female/female RS232 cable between the DB9 connector
+ (CN12 for USART1, CN8 for USART2 in the STM3210E-EVAL board)
+ and PC serial port.
+
+
+ - Hyperterminal configuration:
+ - Word Length = 8 Bits
+ - One Stop Bit
+ - No parity
+ - BaudRate = 115200 baud
+ - flow control: None
+
+
+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_usart.c
+ + stm32f10x_gpio.c
+ + stm32f10x_rcc.c
+ + stm32f10x_nvic.c
+ + stm32f10x_flash.c
+
+- Link all compiled files and load your image into target memory
+- Run the example
