Generic Linux devices are supported via SPIDEV, MRAA, RPi native via BCM2835, or using LittleWire.
- Note
- The SPIDEV option should work with most Linux systems supporting spi userspace device.
- Warning
- These install instructions are beginning to age because they were designed with the assumption that the arm-linux-gnueabihf-g** compilers were available and default for the system. If you have problems using the manual install instructions (especially on a 64-bit OS), please try the instructions using CMake.
- Note
- Since wiringPi is no longer maintained or distributed (as of RPi OS 11 bullseye), pigpio is now required for using the radio's IRQ pin. This applies to RPi, SPIDEV, and pigpio drivers. The MRAA driver may provide its own IRQ implementation. Remember that the RPi OS lite variant does not ship with pigpio installed.
Automated Install
Designed & Tested on RPi - Defaults to SPIDEV on devices supporting it
- Install prerequisites if there are any (pigpio, MRAA, LittleWire libraries, setup SPI device etc)
- Download the install.sh file from http://tmrh20.github.io/RF24Installer/RPi/install.sh
wget http://tmrh20.github.io/RF24Installer/RPi/install.sh
- Make it executable
- Run it and choose your options
- Run an example from one of the libraries
cd rf24libs/RF24/examples_linux
Edit the gettingstarted example, to set your pin configuration nano gettingstarted.cpp
make
sudo ./gettingstarted
Manual Install
- Install prerequisites if there are any (pigpio, MRAA, LittleWire libraries, setup SPI device etc)
- Note
- See the MRAA documentation for more info on installing MRAA
- Make a directory to contain the RF24 and possibly RF24Network lib and enter it
mkdir ~/rf24libs
cd ~/rf24libs
- Clone the RF24 repo
git clone https://github.com/tmrh20/RF24.git RF24
- Change to the new RF24 directory
Configure build environment using
script. It auto detectes device and build environment.
For overriding autodetections, use command-line switches, see
for description.
- Build the library, and run an example file Edit the gettingstarted example, to set your pin configuration
ano gettingstarted.cpp
make
sudo ./gettingstarted
Build using SPIDEV
- Make sure that spi device support is enabled and /dev/spidev<a>.<b> is present
- Manual Install using SPIDEV:
./configure --driver=SPIDEV
make
sudo make install
- See the gettingstarted example for an example of pin configuration
