This repository is kept for historical purposes, to go to updated_repository: gnu-sandhi/sandhi

Sandhi

Sandhi is a visual programming software particularly for control systems. Sandhi is forked from GNU Radio project which uses GRAS (GNU Radio Advanced Scheduler) https://github.com/guruofquality/gras/wiki

Quick Build Guide

Dependencies

Sandhi is conglomeration of lot of libraries and softwares. It uses GNU Radio at its core. For computational purposes, Scilab and Octave can be interfaced with Sandhi. Sandhi uses a special wrapper called Sciscipy which allows one to call scilab functions from python without having to worry about datatype conversion.

Installing GNU Radio dependencies

If on Ubuntu 12.04, one can directly install using command-

sudo apt-get -y install git-core autoconf automake make libtool g++ python-dev swig \
pkg-config libboost1.48-all-dev libfftw3-dev libcppunit-dev libgsl0-dev \
libusb-dev sdcc libsdl1.2-dev python-wxgtk2.8 python-numpy \
python-cheetah python-lxml doxygen python-qt4 python-qwt5-qt4 libxi-dev \
libqt4-opengl-dev libqwt5-qt4-dev libfontconfig1-dev libxrender-dev \
python-serial python-matplotlib

Please note that Sandhi has been known to not work libboost1.49 available in Ubuntu 12.10

Sciscipy

Sciscipy is must for Sandhi's control blocks to work; to install:

Clone sciscipy-1.0.0 from our repository; run install script from the directory with sudo privileges to automatically pull all dependencies for Sciscipy, build and install it

git clone https://github.com/manojgudi/sciscipy-1.0.0.git
cd sciscipy-1.0.0/
sudo ./install

Get the source code

For Users

You can do a shallow clone for a quick clone of source code

git clone --depth 1 http://github.com/manojgudi/sandhi.git

For Developers

Setting up git subtree: will be added soon

FAQ (Frequently Asked Questions)

  1. I am not able to run SBHS with plant-controller block of Sandhi.

Mostly you don't have sufficient permissions to access /dev/ttyUSB0 (which is SBHS device node in Ubuntu). To solve this, just add your user to dialout group.

sudo adduser `whoami` dialout

Logout User and check.
