## What it is
Firmware and sigrok driver that turns a Raspberry Pi Pico (RP2040/RP2350) into a low-cost logic analyzer and oscilloscope. It supports 21 digital and 3 analog channels with mixed-mode capture, working with PulseView and sigrok-cli.

## Use cases
- use a raspberry pi pico as a logic analyzer
- cheap oscilloscope with sigrok
- capture digital signals with pulseview
- mixed digital and analog signal capture
- debug embedded electronics on a budget
- turn rp2040 into a signal analyzer

## When to choose
- you already own a Raspberry Pi Pico and need basic logic analysis or oscilloscope capture
- you use sigrok/PulseView and want a cheap multi-channel capture device
- you need mixed digital plus analog capture on a hobby budget

## When to avoid
- you need high sample rates, deep memory, or professional-grade accuracy of commercial scopes
- you need isolated or high-voltage measurements
- you don't want to flash firmware onto a microcontroller

## Facets
- artifact type: application
- maturity: active
- function: testing, developer-tools, monitoring
- domain: developer-tools, hardware, embedded-systems
- platform: cross-platform, embedded, windows
