@par Example Description
Re-routing of the C library printf function to the UART.
The UART outputs a message on the HyperTerminal.
Board: STM3210E-EVAL RevD
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 STM32F103xG devices.
- This example has been tested with STM3210E-EVAL RevD board and can be
easily tailored to any other supported device and development board.
- STM3210C_EVAL Set-up
- Connect a null-modem female/female RS232 cable between the DB9 connector
CN12 (USART1) and PC serial port if you want to display data on the HyperTerminal.
- 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
