This library generates simple waveforms that can be used to generate different type of audio signals.
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI¶
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-waveform
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-waveform
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-waveform
This example generates one wavelength of a 440hz sine wave when played at 16 kilosamples per second:
from adafruit_waveform import sine wave = sine.sine_wave(16000, 440)
API documentation for this library can be found on Read the Docs.
