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)
