Please see the full documentation at http://tmrh20.github.io/RF24Network/

If SPI is not already enabled, load it on boot:

sudo raspi-config  

A. Update the tool via the menu as required
B. Select Advanced and enable the SPI kernel module
C. Update other software and libraries:

 sudo apt-get update  
 sudo apt-get upgrade  

A. Make a directory to contain the RF24 and possibly RF24Network lib and enter it:

mkdir ~/rf24libs  
cd ~/rf24libs  

B. Clone the RF24 Repo

git clone https://github.com/tmrh20/RF24.git RF24  

C. Change to the new RF24 directory

cd RF24  

D. Build the library, and run an example file:

sudo make install
cd examples_RPi  
make  
sudo ./gettingstarted  

A. Enter the same directory that contains the RF24 library folder

cd ~/rf24libs  

B. Clone the RF24Network Repo

git clone https://github.com/tmrh20/RF24Network.git RF24Network  

C. Copy the RF24Network folder to the current directory, and delete the rest

cd RF24Network  

D. Build the library

sudo make install
cd examples_RPi  
make  
sudo ./helloworld_rx   OR   sudo ./helloworld_tx  

Using pin 15/GPIO 22 for CE, pin 24/GPIO8 (CE0) for CSN

Can use either RPi CE0 or CE1 pins for radio CSN. Choose any RPi output pin for radio CE pin.

Constructor:

RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS0, BCM2835_SPI_SPEED_8MHZ);
or
RF24 radio(RPI_V2_GPIO_P1_15,BCM2835_SPI_CS1, BCM2835_SPI_SPEED_8MHZ);

RPi B+:
RF24 radio(RPI_BPLUS_GPIO_J8_15,RPI_BPLUS_GPIO_J8_24, BCM2835_SPI_SPEED_8MHZ);
or
RF24 radio(RPI_BPLUS_GPIO_J8_15,RPI_BPLUS_GPIO_J8_26, BCM2835_SPI_SPEED_8MHZ);

Pins:

See http://www.airspayce.com/mikem/bcm2835/index.html for BCM2835 class documentation.
Note: The BCM library has been customized slightly to allow use of hardware CE pins not in use for SPI, and to include a millis() function.

Based on the arduino lib from J. Coliz [email protected].
the library was berryfied by Purinda Gunasekara [email protected].
then forked from github stanleyseow/RF24 to https://github.com/jscrane/RF24-rpi
Network lib also based on https://github.com/farconada/RF24Network

Currently optimized and aligned with Arduino fork of libraries by TMRh20:
https://github.com/tmrh20/RF24/RPi and https://github.com/tmrh20/RF24Network/RPi
