Arduino driver for nRF24L01 2.4GHz Wireless Transceiver

Design Goals: This library is designed to be...

• Maximally compliant with the intended operation of the chip
• Easy for beginners to use
• Consumed with a public interface that's similiar to other Arduino standard libraries
• Built against the standard SPI library.

Please refer to:

• Documentation Main Page
• RF24 Class Documentation

• Chip Datasheet

This chip uses the SPI bus, plus two chip control pins. Remember that pin 10 must still remain an output, or the SPI hardware will go into 'slave' mode.
