Quick2Wire Python API

A Python library for controlling the hardware attached to the Raspberry Pi's header pins.

Status: Tested on Raspberry Pi Zero 2W running Raspberry Pi OS (bookworm) in May-2024.

Process

sudo apt install i2c-tools vim git build-essential -y

sudo raspi-config nonint do_i2c 0

sudo raspi-config nonint get_i2c

ls /dev/i2*

sudo i2cdetect -y 1  # For modern Pis, you will need to specify 1 as the port

Set up this library:

python3 setup.py install --user  # inside the repository folder

Set up pigpio:

wget https://github.com/joan2937/pigpio/archive/master.zip

unzip master.zip
cd pigpio-master
make
sudo make install

Usage:

sudo pigpiod

python3 radio_clk.py

python3 radio.py

At this point the i2cdetect command is able to detect the Si4732.
