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:
| PIN | NRF24L01 | RPI | RPi -P1 Connector |
|---|---|---|---|
| 1 | GND | rpi-gnd | (25) |
| 2 | VCC | rpi-3v3 | (17) |
| 3 | CE | rpi-gpio22 | (15) |
| 4 | CSN | rpi-gpio8 | (24) |
| 5 | SCK | rpi-sckl | (23) |
| 6 | MOSI | rpi-mosi | (19) |
| 7 | MISO | rpi-miso | (21) |
| 8 | IRQ | - | - |
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
