pygpp 0.0.1

A Python abstraction layer for GW-Instek GPP power supplies

pyGPP

pyGPP is a Python Hardware Abstraction Layer (HAL) over SCPI commands using PyVISA for controlling GW-Instek GPP series power supplies. Currently, these models are supported:

• GPP-3060/6030/3650

Status

⚠️ Early development (v0.0.1) - API may change

Prerequisites

• Hardware: GW-Instek GPP-3060, GPP-3650, or GPP-6030.
• Drivers:
  • GW-Instek USB Driver (for USB connection).
  • VISA Backend (choose one):
    • NI-VISA (recommended, full-featured)
    • PyVISA-py (pure Python, no binary install): pip install pyvisa-py
• Tooling: uv (optional, )

Installation

As a Dependency (for users)

If you want to use pyGPP in your own project, install it directly from the repository:

uv add git+https://gitlab.com/samshahrokni/pyGPP.git

Or with pip:

pip install git+https://gitlab.com/samshahrokni/pyGPP.git

Usage

from src.pygpp import GPP3060

with GPP3060(address='ASRL3::INSTR') as psu:
    psu.ch1.set_voltage(5.0)  # set voltage to 5V
    psu.ch1.set_ocp(1.0)  # set current overprotection to 1A
    psu.ch1.enable()

    measurement = psu.ch1.measure()
    print(measurement)

For more examples, see examples/ directory.

For Development (for contributors)

Clone the repository and sync dependencies (automatically fetches Python 3.14+):

git clone https://gitlab.com/samshahrokni/pyGPP.git
cd pyGPP
uv sync --all-extras
pre-commit install

Notes

• Incomplete Implementation: Not all SCPI commands are implemented.
• Reference: See the GPP Series User Manual for the full command list.
