Basic_RX.ino

/*

Demonstrates simple RX and TX operation.
Any of the Basic_TX examples can be used as a transmitter.
Please read through 'NRFLite.h' for a description of all the methods available in the library.

Radio    Arduino
CE    -> 9
CSN   -> 10 (Hardware SPI SS)
MOSI  -> 11 (Hardware SPI MOSI)
MISO  -> 12 (Hardware SPI MISO)
SCK   -> 13 (Hardware SPI SCK)
IRQ   -> No connection
VCC   -> No more than 3.6 volts
GND   -> GND
