Python Bindings for Digilent WaveForms API

DwfPy is a Python package that allows you to access Digilent WaveForms devices via Python. It provides a low-level API with complete access to the Digilent WaveForms API, and also a simple but powerful high-level API, which allows you to configure WaveForms devices with a single statement.

For instance, to output a 1kHz sine-wave on an Analog Discovery, you can simply write:

import dwfpy as dwf

with dwf.Device() as device:
    print('Generating a 1kHz sine wave on WaveGen channel 1...')
    device.analog_output['ch1'].setup('sine', frequency=1e3, amplitude=1, start=True)
    input('Press Enter key to exit.')

Features

• Pythonic abstraction of Digilent Waveforms API.
• Low-level API with complete access to the Digilent Waveforms API.
• Powerful high-level API that supports one-line configuration statements.
• Supports all sub-modules, such as oscilloscope, arbitrary waveform generator, logic analyzer, pattern generator, digital I/O, and power supplies.
• Works with all WaveForms devices, such as the Analog Discovery 2, the Analog Discovery 3, or the Digital Discovery.

Installing DwfPy

You can install the DwfPy package from PyPI using pip:

pip install dwfpy

In order to use the DwfPy package, you need Python 3.8 or higher.

As DwfPy builds on top of the WaveForms API, you need to install the WaveForms software, which includes the required runtime components to access the WaveForms devices.

The source code for the DwfPy package can be found at GitHub at https://github.com/mariusgreuel/dwfpy.

Examples

You can find Python examples using DwfPy in the dwfpy GitHub repository at https://github.com/mariusgreuel/dwfpy/tree/main/examples.

Documentation

You can find the DwfPy user's guide at https://dwfpy.readthedocs.io/.

Detailed information about the Digilent Waveforms API is available from the Digilent WaveForms SDK Reference Manual.
