Introduction

PyDFUUtil provides for easy access to the devices that supports DFU interface over host machine's Universal Serial Bus (USB)
system for Python 3.
PyDFUUtil is an open realisation of original dfu-util
and thin wrapper over libusb (uses PyUsb library as a backend).

[!WARNING]
The current status of the project is BETA version.
Use it for your own risk

[!TIP]
Searching for contributors for testing the library

Requirements and platform support

Since PyDFUUtil uses the libusb library it has similar dependencies for using libusb
It uses python construct library for simple unpacking C-structs.
PyDFUUtil primarily tested on Linux and Windows,
but also can work on each platform where PyUsb and construct libraries are available, including MacOS

Installing
PyDFUUtil is generally installed through pip
# the latest official release
python -m pip install pydfuutil

# install a specific version (e.g. 0.0.1b1)
python -m pip install pydfuutil==0.0.1b1

Usage
dfu-util
pydfuutil -h
# or
python -m pydfuutil -h

About
Dfu-util - Device Firmware Upgrade Utilities
Dfu-util is the host side implementation of the
DFU 1.0 and
DFU 1.1
specification of the USB forum.
DFU is intended to download and upload firmware to devices connected over
USB. It ranges from small devices like micro-controller boards up to mobile
phones. With dfu-util you are able to download firmware to your device or
upload firmware from it.
dfu-util has been tested with Openmoko Neo1973 and Freerunner and many
other devices.

Project is in develop, it fulls of not implemented statements that's not according to original dfu-util!
