Example description
===================
This example provides a basic communication between USART1 and USART2 using 
interrupts.
USART2 sends TxBuffer2 to USART1 which sends TxBuffer1 to USART2. The data received 
by USART1 and USART2 are stored respectively in RxBuffer1 and RxBuffer2. The data
transfer is managed in USART1_IRQHandler and USART2_IRQHandler in stm32f10x_it.c file.

USART1 and USART2 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
       
        
Directory contents
==================
stm32f10x_conf.h  Library Configuration file
stm32f10x_it.h    Interrupt handlers header file
stm32f10x_it.c    Interrupt handlers
main.c            Main program


Hardware environment
====================
Connect USART1_Tx(PA.09) to USART2_Rx(PD.05) and USART1_Rx(PA.10) to USART2_Tx(PD.06)
(in the STM3210B-EVAL board, connect a null-modem female/female RS232 cable between
 CN5 and CN6).
  
  
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
