Pydgilib provides python bindings for Atmel® Data Gateway Interface (DGI) devices. See the Data Gateway Interface user guide for further details. This package works best if you have Atmel Studio 7.0 installed. If you do it will automatically make use of the installed files it requires. Otherwise you can download the required DLL from Atmel here and point pydgilib to the location where you downloaded the file.

Features

The main features of this library are:

• It wraps the C functions of DGILib in python functions
• It provides a class to easily log data from the power and gpio interfaces to a .csv file or a plot (using matplotlib)
• It provides a function that wraps atprogram.exe and make.exe so it can compile projects and flash them to a board

The documentation of all the functions can be found in this overview or this list.

Installation

You will need to install pydgilib in a 32-bit Python environment on Windows because DGILib.dll is compiled for 32-bit. Other operating systems are not supported.

Installation via pip

Normal installation:

$ pip install pydgilib

Static Installation

If you want to install a static copy of the master you can run:

$ pip install git+https://github.com/EWouters/pydgilib

Development Installation

1. Clone the repo:

   $ git clone https://github.com/EWouters/pydgilib.git
   

2. Install symlinked to repo:

   $ pip install -e .
   

If you want to be able to run the tests or compile the docs run instead:

$ pip install -e .[test,docs]

Getting Started

1. Connect your device that supports DGI

2. Print the serial number of your device:

   >>> from pydgilib import DGILib
   >>> with DGILib() as dgilib:
   ...     print(dgilib.device_sn)
   ...
   b'ATML3138061800001604'
   

3. Log the current of the board and the states of the gpio pins for one second and write the results to .csv files:

   >>> from pydgilib_extra import DGILibExtra
   >>> with DGILibExtra() as dgilib:
   ...     dgilib.logger.log(1)
   ...
   

4. Log the current of the board and the states of the gpio pins for one second and show a plot of the results:

   >>> from pydgilib_extra import DGILibExtra, LOGGER_PLOT
   >>> with DGILibExtra(loggers=[LOGGER_PLOT]) as dgilib:
   ...     dgilib.logger.log(1)
   ...
   {48: <pydgilib_extra.dgilib_data.InterfaceData object at 0x00F22A90>, 256: <pydgilib_extra.dgilib_data.InterfaceData object at 0x00F229F0>}
