Example description
===================
This example provides a description of how  to use the USART1 interrupts to 
communicate with the hyperterminal.
The USART1 sends a predefined buffer to the hyperterminal and still waiting 
for a string from the hyperterminal which length is defined by RxBufferSize. 
The communication is managed by Transmit and Receive interrupts. 

First, the USART1 sends the TxBuffer to the hyperterminal and still waiting for
a string from the hyperterminal that you must enter.
The string that you have entered is stored in the RxBuffer array. The receive
buffer have a RxBufferSize bytes as maximum.

The USART1 is configured as follow:
    - BaudRate = 9600 baud  
    - Word Length = 8 Bits (7 data bit + 1 parity bit)
    - Two Stop Bit
    - Odd parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

Note: When the parity is enabled, the computed parity is inserted at the MSB
position of the transmitted data.

  
Directory contents

stm32f10x_it.h    Interrupt handlers header file
stm32f10x_it.c    Interrupt handlers source file

Hardware environment
====================
 - The USART1 signals (Rx and Tx) must be connected to a DB9 connector using
   a RS232 transceiver.

 - Connect a null-modem female/female RS232 cable between the DB9 connector 
   (CN6 on STM3210B-EVAL board) and PC serial port.  

 - Hyperterminal configuration:
    - Word Length = 7 Bits
    - Two Stop Bit
    - Odd parity
    - BaudRate = 9600 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_nvic.c
  + stm32f10x_rcc.c
  + stm32f10x_flash.c
    
- Link all compiled files and load your image into either RAM or Flash
- Run the example
