Installation

You can install the library using npm:

npm i @finalspark-np/livemea_ts

Usage

To use the library, import the LiveMEA class from the library:

import { LiveMEA } from '@finalspark-np/livemea_ts';

// Create instance
const liveMEA = new LiveMEA();

// Record a single sample of MEA 1
liveMEA.recordSample(1)
  .then((data) => {
    console.log(data); // Contains timestamp and 32x4096 electrode data array
  });

// Record multiple samples of MEA 1
liveMEA.recordNSamples(1, 10)
  .then((samples) => {
    console.log(samples); // Array of samples, each with timestamp and electrode data
  });

API

LiveMEA

The main class for interacting with live MEA data from the FinalSpark service.

Methods

recordSample(meaId?: number): Promise<LiveData>

Records a single sample of live MEA data.

• meaId (optional): The MEA ID to use (1-4). Defaults to 1.
• Returns: Promise resolving to LiveData containing:
  • timestamp: Date object when the sample was recorded
  • data: 32x4096 array where each row represents one electrode's samples

recordNSamples(meaId?: number, n?: number): Promise<LiveData[]>

Records multiple samples of live MEA data.

• meaId (optional): The MEA ID to use (1-4). Defaults to 1.
• n (optional): Number of samples to record. Defaults to 10.
• Returns: Promise resolving to array of LiveData objects

Types

interface LiveData {
    timestamp: Date;
    data: number[][];  // 32x4096 array
}

Error Handling

The methods will throw errors in these cases:

• Invalid MEA ID (must be 1-4)
• Connection failures
• Server timeout
