# Release Notes for STDATALOG_PYSDK Copyright © 2025 STMicroelectronics

ST logo{.logo}

Purpose

The STDATALOG_PYSDK is a comprehensive Python framework designed to facilitate the capture, processing, and visualization of data from a wide range of sources, including sensors, algorithms, simulated signals, and telemetries from actuators.

This software development kit is designed with an open and modular architecture, making it an excellent resource for data scientists and embedded designers. STDATALOG-PYSDK has been developed in Python 3.13, but it is compatible also with Python 3.12, 3.11 and 3.10.

It provides a range of tools and utilities designed to simplify the development of applications that use data from ST system solutions.

It includes Python scripts to create, elaborate, and organize data into structured datasets. These datasets are compatible with mainstream data science toolchains, promoting reusability across multiple projects. Additionally, the scripts can be easily integrated into any data science design workflow.

It is formerly known as HSDPython_SDK, previously distributed in FP-SNS-DATALOG1, FP-SNS-DATALOG2, and FP-IND-DATALOGMC function packs
