General Linux/Raspberry Pi

RF24 supports a variety of Linux based devices via various drivers. Some boards like RPi can utilize multiple methods to drive the GPIO and SPI functionality.

Potential PreConfiguration

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

sudo raspi-config

  1. Update the tool via the menu as required

  2. Select Advanced and enable the SPI kernel module

  3. Update other software and libraries

    sudo apt-get update
sudo apt-get upgrade

Build Options

The default build on Raspberry Pi utilizes the included BCM2835 driver

For available build options, read the output from

./configure --help

Configure the build options automatically by running

./configure

Manual install

make
sudo make install

Pins Connections and Pin Configuration

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

Can use any available SPI BUS for CSN.

In general, use RF24Revamped radio(<ce_pin>, <a>*10+<b>); for proper constructor to address correct spi device at /dev/spidev<a>.<b>

Choose any GPIO output pin for radio CE pin.

Based on the arduino lib from J. Coliz

the library was berryfied by Purinda Gunasekara

then forked from https://github.com/stanleyseow/RF24 to https://github.com/jscrane/RF24-rpi

Network lib also based on https://github.com/farconada/RF24Network
