@par Example Description
Re-routing of the C library printf function to the UART.
The UART outputs a message on the HyperTerminal.
Board: STM32VL-Discovery
Tx Pin: PA.09
Rx Pin: PA.10

|_STM32_Board_____________|
The USART is configured as follows:
- BaudRate = 9600 baud
- Word Length = 8 Bits (7 data bit + 1 parity bit)
- One Stop Bit
- Odd parity
- Hardware flow control disabled (RTS and CTS signals)
- Reception and transmission are enabled in the time
@note USARTx/UARTx instance used and associated resources can be updated in "main.h"
file depending hardware configuration used.
@note When the parity is enabled, the computed parity is inserted at the MSB
position of the transmitted data.

@par Hardware and Software environment
- This example runs on STM32F100xB devices.
- This example has been tested with STM32VL-Discovery board and can be
easily tailored to any other supported device and development board.
- STM32_VL_DISCOVERY Set-up
- If you want to display data on the HyperTerminal, please connect USART1 TX (PA9)
to RX pin of PC serial port (or USB to UART adapter).
USART1 RX (PA10) could be connected similarly to TX pin of PC serial port.
- Hyperterminal configuration:
- Word Length = 7 Bits
- One Stop Bit
- Odd parity
- BaudRate = 9600 baud
- flow control: None
@par How to use it ?
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Run the example
