Getting Started

Overview

The BioAmp Visualizer is a web application designed for real-time signal visualization, particularly tailored for bio-potential signals. This tool serves as an advanced alternative to the standard Arduino serial plotter, offering enhanced functionality for researchers and enthusiasts working with BioAmp hardware. The application provides a user-friendly interface for displaying time-series data streams, with features including multi-channel plotting, adjustable graph speed, the ability to pause, resume, record and save data in CSV format. By combining these capabilities, the BioAmp Visualizer aims to streamline the process of analyzing and interpreting bio-potential signals.

Compatible Browsers

The web application is designed to ensure compatibility with the Web Serial API, which is essential for its functionality. The Web Serial API enables web applications to communicate with serial devices, such as microcontrollers and other hardware interfaces, directly from the browser.

Currently, the Web Serial API is supported by the of Google Chrome, Microsoft Edge and Opera. If the user’s browser does not support this API, the application will display a message informing them of the incompatibility and suggesting the use of a supported browser.

For more detailed information on browser compatibility and implementation details, please refer to the MDN Web Docs on the Web Serial API.
