===============================================
A virtual environment is a way to have multiple, parallel instances of the Python interpreter, each with different package sets and different configurations.
Each virtual environment contains a discrete copy of the Python interpreter, including copies of its support utilities. It also protects your system in case of problems with the packages.

The multiplexing of the channels is a mechanical multiplexing based on OMRON's manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.

The philosophy of Ohmpi
**************************
=======================
The philosophy of Ohmpi V2.00 is to offer a new DIY multielectrode resistivity meter. It is a resistivity meter with 64 electrodes , which can be upgraded to 128 electrodes.
It is limited to low-current injection,but suitable for small laboratory experiments and small field time-lapse monitoring.
Ohmpi, is developed by a team that seeks to share all its experience and wishes to improve and offer a more and more robust tool to the community.Ohmpi V2.00 is a completely different version from the previous one.
We will stop the development on the previous version, to dedicate our efforts on this new version.
