10 * DESCRIPTION: for nRF9E5
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.
