About this app

Combine Scoppy with a Raspberry Pi Pico to create a 500kS/s oscilloscope and 25MS/s logic analyzer.

Key Features:
- Horizontal scale and position adjustments
- Vertical scale and position adjustments
- Trigger channel and level selection
- Rising edge and falling edge triggers
- Auto and Normal triggering
- Continuous (Run) and Single capture modes
- Memory depth up to 100kpts for single captures
- Vertical and Horizontal Cursors
- Auto or fixed sample rate
- % pre-trigger samples setting
- Signal Generator
--- square wave (100Hz - 1.25MHz)
--- 1kHz PWM sine wave
- X-Y Mode
--- Hann, Hamming, Blackman and Rectangle windows
--- vertical and horizontal cursors
--- dBm, dBmV and V vertical units
--- option to display both channels simultaneously
--- option to display the scope window alongside the FFT
- Probe attenuation settings eg. 1X, 10X, custom

- Two Channels
- Up to 500k samples per second (shared between channels)
- Time/Div: 5us - 20secs
- Up to 4 configurable voltage ranges per channel (see help for details)

Logic Analyzer
- Eight Channels
- Up to 25M samples per second (per channel)
- Time/Div: 50ns - 100ms

Analog Front End
Connect the input signal directly to the Pico ADC pins for 0-3.3V inputs or build your own analog front end. Several cheap and easy to build open-source designs can be found at

Easy to set up and use. Excellent on screen controls. I have upgraded to the paid version and it is well worth it. Obviously not a replacement for an oscilloscope costing hundreds but it can do a very useful job. I have tested it with a signal generator and the results are excellent. First task was to analyse a 20Hz pwm signal (that controls a treadmill motor) - results were spot on. Will be very useful for a number of tasks.

Okay... Technically I have yet to really dig in to this app and really push it to the limits... But I've hooked it up and so far it works as promised. What a brilliant way to use a Pi Pico! Definitely worth the $2.12 (CAD) license fee... Next steps will be further testing and then to design a front end to interact with the voltage range settings. If you've got a Pico around and need a nice little portable scope, you'll have a hard time finding anything better for $2! Thank you for this!!🙂

Easy install and rock solid triggering. Fast enough to be actually useful unlike some arduino scopes.
