pico-sdk

High performance, gap-free streaming from any Pico Technology oscilloscope.

Note: This is not an official Pico Technology package

This package wraps all current Pico oscilloscope drivers in a high-level, common API written in Rust. This API is compiled to native code and exposed to Node through simple C bindings.

Supported platforms

Node.js >= 12 on:

  • Windows (32/64bit)
  • macOS (64bit)
  • Linux (64bit)
import { PicoDevice } from 'pico-sdk';

const device = PicoDevice.open('ABC/123', true);

console.log('Device serial:', device.serial);
const ranges = device.getChannelRanges('A');

// String case and white space are ignored
device.enableChannel('A', '200mV');
device.enableChannel('b', '20 v', 'dc');
 
device.setCallback((data) => {
  // Callback data is Map<string, Float32Array> containing an entry
  // for each channel and values in volts
  console.log('Received streaming data...');

// Wait here and handle data capture...
 
device.stopStreaming();
 
// The device should be closed after use to avoid memory leaks
