## Raspberry Pi Configuration:
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 RF24
C. Copy the RPi library folder to the current directory, and delete the rest
cd RF24
D. Build the library, and run an example file:
sudo make install
cd examples
make
sudo ./gettingstarted
# RPi - RF24Network Quick-Start
A. Enter the same directory that contains the RF24 library folder
cd ~/rf24libs

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

Note: The BCM library has been customized slightly to allow use of hardware CE pins not

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
