Library functions are mostly the same.
See the included examples for RPi specific usage
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 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 install
cd examples 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 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 install
cd examples 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);
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
