PYVIUM
Python wrapper for the IviumSoft driver DLL, enabling control of Ivium potentiostats and data processing directly from Python.
PYVIUM provides both:
- Direct access to the original IviumSoft Core functions
- Higher-level Pythonic interface with exception handling and extended utilities
Features
- Full access to IviumSoft driver DLL functions
- Python-friendly interface
- Exception management
- Data processing tools
- Batch conversion utilities
- Batch mode synchronization
Requirements
PYVIUM requires IviumSoft to be installed on a Windows machine, as it uses the official driver DLL.
Download IviumSoft here:
https://www.ivium.com/support/#Software%20update
This version of PYVIUM contains the DLL from IviumSoft release 4.1247.
Installation
Install PYVIUM easily with pip:
pip install pyvium
Or with poetry:
poetry add pyvium
Quick Start
Using Core functions (direct DLL access)
To use the same functions available in the "IviumSoft driver DLL" you can import the Core class as follows. All functions return a result code (integer) and a result value if available. For further information you can check the IviumSoft documentation.
from pyvium import Core
Core.IV_open()
Core.IV_getdevicestatus()
Core.IV_close()
Using Pyvium high-level interface (recommended)
This is a wrapper around the Core functions that adds a few things:
- Exception management (you can find an example here)
- Cleaner syntax
- Additional functionality
from pyvium import Pyvium
Pyvium.open_driver()
Pyvium.get_device_status()
Pyvium.close_driver()
Data processing tools
This offers further functionality in data processing:
from pyvium import Tools
Tools.convert_idf_dir_to_csv()
