code: 

unsigned char val=0;
/----------------------------------------------------------------------------
static void handle_uart_interrupt (void* context, alt_u32 id)
{
  uval++;
  IOWR_ALTERA_AVALON_PIO_DATA( PIO_0_BASE ,uval); 
}
//----------------------------------------------------------------------------
//static alt_avalon_uart_dev gS;;  
int main()
{ 
    IOWR_ALTERA_AVALON_UART_CONTROL ( UART_0_BASE, 0x180);
    alt_irq_register( UART_0_IRQ , &uart_0, handle_uart_interrupt );  
    return 0;
}
