## Overview

VITAL-CORE is a prototype for acquiring physiological measurements, logging them locally, and presenting live/history monitoring with ECG visualization, AI summaries, voice retrieval, and emergency alerts. The main documented workflow runs from MCU sensor acquisition over UART through CSV logging to a monitoring dashboard; separate scripts provide HL7 generation/conversion and network alert reception. The sampled files show several parallel or mismatched implementations, so uncertain connections—especially GUI-to-assistant wiring—are left out.

Main entry points: [`patient_data.csv`](https://github.com/diya411/data_logging_system_for_physiological_parameters/blob/main/patient_data.csv) (Patient CSV), [`AI_voice_assistence.py`](https://github.com/diya411/data_logging_system_for_physiological_parameters/blob/main/AI_voice_assistence.py) (Voice data retrieval), [`icu.py`](https://github.com/diya411/data_logging_system_for_physiological_parameters/blob/main/icu.py) (ICU monitor), [`Signal_Gen.c`](https://github.com/diya411/data_logging_system_for_physiological_parameters/blob/main/Signal_Gen.c) (MCU firmware)
