    uart.c:
          UART2 driver for SpARM-board v1

    pin-info:
           PA2 - TX
           PA3 - RX

To enable UART use the following line:
	UART_init();
To use UART on interrupt base use:
	UART_INT_init();

This file initialize the UART on the ARM-board v5.
To send data to the UART use:
	UART_printf(*string);

To read the UART without interrupt use:
	char = USART2->DR & 0xFF;

In the interrupt routine the char is send back to the terminal
