Optimized Raspberry Pi RF24 and RF24 Network Libraries

General Documentation: http://tmrh20.github.io

Library functions are mostly the same.
See the included examples for RPi specific usage

##Raspberry Pi - PreConfig

####Possible pre-configuration:
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  

RPi - RF24 Quick-Start

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 rtemp  

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

	mv rtemp/RPi/RF24 ./  
    rm -r rtemp  
	cd RF24  

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

    sudo make  
	cd examples  
	sudo make  
	sudo ./gettingstarted  

RPi - RF24Network Quick-Start

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 ntemp  

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

	mv ntemp/RPi/RF24Network ./  
	rm -r ntemp  
	cd RF24Network  

D. Build the library

    sudo make  
	cd examples  
	sudo make  
	sudo ./helloworld_rx   OR   sudo ./helloworld_tx  

Connection Info

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);

Pins:

NRF24L01	RPI	P1 Connector
VCC	rpi-3v3	(17)
GND	rpi-gnd	(25)
CE	rpi-gpio22	(15)
CSN	rpi-gpio8	(24)
SCK	rpi-sckl	(23)
MOSI	rpi-mosi	(19)
MISO	rpi-miso	(21)

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 maniacbug@ymail.com.
the library was berryfied by Purinda Gunasekara purinda@gmail.com.
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
