pd-buddy-python
===============

Python library for working with the PD Buddy Sink Serial Console
Configuration Interface

Features
--------

-  Provides a Pythonic interface to the PD Buddy Sink shell commands
-  Configuration is represented as a SinkConfig object
-  SinkConfig objects can be manipulated locally and written to the
   device with one method call

Examples
--------

Open the first PD Buddy Sink device and read its configuration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

::

    >>> import pdbuddy
    >>> pdbs = pdbuddy.Sink(list(pdbuddy.Sink.get_devices())[0])
    >>> pdbs.get_cfg()
    SinkConfig(status=SinkStatus.VALID, flags=SinkFlags.NONE, v=5000, i=3000)
    >>> print(pdbs.get_cfg())
    status: valid
    flags: (none)
    v: 5.00 V
    i: 3.00 A

Locally manipulate a SinkConfig object
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

::

    >>> cfg = pdbs.get_cfg()
    >>> cfg.v = 20000
    >>> cfg.i = 2250
    >>> cfg.flags |= pdbuddy.SinkFlags.GIVEBACK
    >>> cfg
    SinkConfig(status=SinkStatus.VALID, flags=SinkFlags.GIVEBACK, v=20000, i=2250)

Write the SinkConfig object to flash
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

::

    >>> pdbs.set_tmpcfg(cfg)
    >>> pdbs.write()
    >>> pdbs.get_cfg()
    SinkConfig(status=SinkStatus.VALID, flags=SinkFlags.GIVEBACK, v=20000, i=2250)

Requirements
------------

-  Python 2.7, 3.6
-  pySerial >= 3.0
-  aenum >= 2.0 (if using Python < 3.6)
