pico-sdk 0.1.2

Stream gap-less data from Pico Technology oscilloscopes

pico_sdk

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

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 Python through simple C bindings.

Supported platforms

Python >= 3.6 on:

• Windows (32/64bit)
• macOS (64bit)
• Linux (64bit)
