Requirements

Python 3.7 or above is required.

  • PyFtdi v0.53 is the last PyFtdi version to support Python 3.6.

    • Python 3.6 has reached end-of-life on December 23rd, 2021.

  • PyFtdi v0.52 is the last PyFtdi version to support Python 3.5.

    • Python 3.5 has reached end-of-life on September 5th, 2020.

PyFtdi relies on PyUSB, which itself depends on one of the following native libraries:

  • libusb, currently tested with 1.0.23

PyFtdi does not depend on any other native library, and only uses standard Python modules along with PyUSB and pyserial.

PyFtdi is beeing tested with PyUSB 1.1.0.

Development

PyFtdi is developed on macOS platforms (64-bit kernel), and is validated on a regular basis on Linux hosts.

As it contains no native code, it should work on any PyUSB and libusb supported platforms. However, M$ Windows is a seamless source of issues and is not officially supported, although users have reported successful installation with Windows 7 for example. Your mileage may vary.

API breaks

Starting with version v0.40.0, several API changes are being introduced. While PyFtdi tries to maintain backward compatibility with previous versions, some of these changes may require existing clients to update calls to PyFtdi.

Do not upgrade to v0.40.0 or above without testing your client against the new PyFtdi releases. PyFtdi versions up to v0.39.9 keep a stable API with v0.22+ series.

See the Major Changes section for details about potential API breaks.
