  11           *
  12           *  nRF9E5/nRF24E1 range demo. Select receiver by shorting P03 and P05 and transmitter by shorting
  13           *  P05 and P06. Uncomment/comment the appropriate #define below to select nRF9E5 or nRF24E1.
  14           *
  15           *  The transmitter continously send one byte packets. Each time the receiver receives a packet the
  16           *  P00 pin is set low (LED1 is turned on on the 9E5 eval board). At the same time a 20ms timer is
  17           *  started and if a new packets is not received before the 20ms time-out the P00 pin is set high
  18           *  (LED1 is turned off). If a new packet is received before the time-out a new 20ms time-out period
  19           *  is started.
  20           *
  21           *  Please remember to turn off the RS232 switch on the receiver and transmitter boards. On the
  22           *  nRF9E5 board turn off all dip-switches on the transmitter and turn on only the LED1 switch on
  23           *  the receiver.
