# PyAnalog: A Pythonic Analog Computer Demonstrator Interface Welcome to PyAnalog, a *research code* written and maintained by [Anabrid GmbH](https://anabrid.com/) and released as Open Source (see below for license). This repository holds a Python package called `pyanalog`. It consists of three modules/libraries which allow to interface analog computers on a software developer/mathematican level: * `PyDDA` is a tool for simple algebraic transformations of equations and circuits as well as their numerical simulation. * `PyFPAA` is a tool for compiling an electrical circuit into a machine architecture. This especially sets digital potentiometers and cross bar switches and relies on a minimalistic hardware description language (HDL) written in YAML. * `PyHyCon` is an interface to a Model-1 Hybrid Controller in order to run a program, steer the operation and gain output data. > :information_source: **Please read the docs**: > As a starting point, see `docs/` or `make docs`. You can find > the generated docs at **https://www.anabrid.dev/pyanalog/dirhtml/** > > We used to serve them from https://pyanalog.readthedocs.io/ but > abandoned ReadTheDocs due to missing features. ## Directory structure ``` . ├── dda - The PyDDA module ├── doc - holding the Sphinx-based documentation ├── Dockerfile - primarily for the CI and testing ├── examples - a large number of applications and examples ├── fpaa - The PyFPAA module ├── hycon - The PyHyCon module ├── LICENSE.ANABRID - Part of the License texts, see below for more information ├── LICENSE.DE - Part of the License texts, see below for more information ├── LICENSE.GPL3 - Part of the License texts, see below for more information ├── LICENSE.py - Generator forthe License texts ├── Makefile - Not really an entry point, but see below ├── misc - Old files, such as Mathematica notebooks or Perl codes ├── README.md - This very file ├── requirements.txt - A dependencies file for pip, see also doc/installation.rst ├── setup.py - A python installer, see also doc/installation.rst └── tests - Unit tests (which also can be useful examples) ``` ## About the Makefile PyAnalog is basically a collection of scripts, so there is no such thing as ``make build``. However, you can try ``make install``, which will basically execute ``setup.py``. Read [doc/installation.rst](doc/installation.rst) for further details. ### The shortest quick start (of PyDDA) This directory holds the package root directory (where `setup.py` lives) of the PyDDA package. This is mostly a pure Python3 package with no dependencies. If you are lazy, you can start using PyDDA right from here: ``` $ git clone git@github.com:anabrid/pyanalog.git $ cd pyanalog $ python3 >>> from dda import * >>> s = BreveState() >>> s.x = Symbol("int", "x", 0.02, 0) >>> print(s) BreveState({'x': int(x, 0.02, 0)}) ``` Please read [doc/installation.rst](doc/installation.rst) for further instructions on how to use the package. It contains also instructions how to install PyAnalog properly. Run `make` to see the various formats the documentation can be generated in. ## About the License Basically, this code is *Open Sourced* by the *GPLv3*.
