/*
 * what is irt ?
 */

  IrT (Ir Transceiver) generate some Ir signals by serial (uart format).
  It bridges uart1 input to Ir, or interpret an action of push-SW
  to Ir signal.

   output uart1:  2400bps (PIO0_2), 38kHz carrier (PIO0_3)
   input: uart0: 57600bps (PIO0_0, same as ISP)
   input: pushSW: (PIO0_1)
            SHORT PUSH: send 'S' when the SW being pushed lesser than   500msec
            LONG PUSH:  send 'L' when the SW being pushed lesser than  1500msec
            REPEAT:    send 'S's when the SW being pushed greater than 1500msec
