OhmPi
Development of a low-cost multi-electrodes resistivity meter for electrical resistivity mesaurement for lab applications, based on raspberry board
Installation
- Download a .zip of this repository (or use
git clone https://gitlab.com/ohmpi/ohmpi.git) - Enter the repository (
cd path/to/ohmpi) and install the software needed. We made a simple script to make it simpler:
./install.sh
The installation script will create a virtual python environement ohmpy (with a 'y' at the end) where all packages specified in requirements.txt will be installed. The script also takes care of creating a configuration for your hardware if you wish.
To activate the environment and set the necessary $PYTHONPATH variable, you can use:
source env.sh
More examples are provided in the documentation.
