Example description
===================
This example shows how to use the UART in order to communicate between the 
STR71x and a PC using RS232 protocol.
The main program waits for the user to send 4 ASCII characters from the PC, and
the UART will echo the same characters back to the PC.
The communication is performed using the Hyperterminal application under 
Windows.
The "STR7" message will be displayed on the PC Hyperterminal window and 
then after each 4 keys pressed the same 4 characters are displayed on the 
hyperterminal.


Directory contents
==================
 71x_conf.h  Library Configuration file
 71x_it.c    Interrupt handlers
 71x_it.h    Interrupt handlers header file
 main.c      Main program
 

Hardware environment
====================
Connect the COM A port on the STR71x-Eval board (mb393) using a serial link to a PC
- Hyperterminal configuration:
    - Word Length = 8 Bits
    - 1 Stop Bit
    - No 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 :
  + 71x_lib.c
  + 71x_apb.c
  + 71x_gpio.c
  + 71x_rccu.c
  + 71x_uart.c
  
- Link all compiled files and load your image into either RAM or FLASH
- Run the example
