- NRF24L01+ Radio Module connected as described, e.g., in [2]

pretty pictures.)
- TMRh20's 'Optimized High Speed nRF24L01+ Driver' [3], installed

Building the NRF24 Python Wrapper
---------------------------------
You have to install the NRF24 Python Library, as a Dependency for the Raspberry Pi Version of Ahoy.
To do that correctly, I have contacted the developer of NRF24 via github
[Python 3 Wrapper not installing properly #845](https://github.com/nRF24/RF24/issues/845)
as I could not get the Python Wrapper for NRF24 to be built.
- Install Raspberry Pi OS lite x86 with raspberry pi imager
- Connect nrf24 module to raspberry pi (as described in github)
- Login with user pi
- Execute `sudo apt update && sudo apt -y upgrade`
- Execute `sudo raspi-config` and
- Select "Expand filesystem" in "Advanced Options"
- Activate "SPI" in "Interface Options"
- "Finish" to exit `raspi-config` Tool, reboot YES!
- Login as pi user again
```code
sudo apt install cmake git python3-dev libboost-python-dev python3-pip python3-rpi.gpio
sudo ln -s $(ls /usr/lib/$(ls /usr/lib/gcc | \
tail -1)/libboost_python3*.so | \
tail -1) /usr/lib/$(ls /usr/lib/gcc | \
tail -1)/libboost_python3.so
git clone https://github.com/nRF24/RF24.git
cd RF24
export RF24_DRIVER=SPIDEV
rm Makefile.inc #just to make sure there is no old stuff
mkdir build && cd build
cmake ..
make
sudo make install
cd ../pyRF24
rm -r ./build/ ./dist/ ./RF24.egg-info/ ./__pycache__/ #just to make sure there is no old stuff
python3 -m pip install --upgrade pip
python3 -m pip install .
python3 -m pip list #watch for RF24 module - if its there its installed
cd ..
cd examples_linux/
python3 getting_started.py # to test and see whether RF24 class can be loaded as module in python correctly
```
If there are no error messages on the last step, then the NRF24 Wrapper has been installed successfully.
