DataLog: a library for interacting with PicoLog hardware

This is a Python library to interface with PicoLog ADC hardware. It provides a Python class to interact with the ADC24, and data structures to represent its outputs. The ADC24 is implemented, but the library is designed to be easily extended for other PicoLog (and potentially non-PicoLog) hardware. It may work with the ADC20 without modification, but this is not tested.

Prerequisites

The following requirements must be met before DataLog is installed:

  • Python 3.5+
  • PicoLog ADC 20/24 hardware and driver (libpicohrdl)

The PicoLog ADC driver can be obtained from PicoTech and must be installed and working before using this library.

Installation

Installation is handled by setup.py. This is most easily handled by pip:

pip3 install datalog

This installs the Python package dependencies automatically. If the above command doesn't make sense, try reading this introduction to pip.

Use

The documentation should help to get you started. Compile it with:

cd doc
make html

The main functionality is implemented in datalog/adc/hrdl/picolog.py and this class can be used on its own.

Site-specific use

We use this library at the University of Glasgow observatory for our magnetometer. We have to calibrate the raw counts coming from the PicoLog unit, as well as upload this data to our FTP server. The set of scripts we use can be found here.
