About this app

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

Key Features:
- Wireless connectivity with the Pico W
- 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
- FFT
--- 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

Oscilloscope
- 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 a 0-3.3V input range or build your own analog front end to extend the input range. Several cheap and easy to build open-source designs can be found at oscilloscope.fhdm.xyz. Affordable front ends are also available for purchase at store.fhdm.xyz.

Ratings and reviews

Usb waiting!continuously!!! And showing "issue with RPI USB DRIVE" HOW TO FIX IT? Edited: now its fixed. 1st i upload scoopy main file. Then i chack dronebot tutorial then i foind scoopy uf2 file, then upload this firmware into rpi file. Now its worked😀😃

The app asked for 5 stars. I don't see a reason not to give it 5. If that changes I'll update this review. Open source projects are the future. This is literally making the world better. Great work!

A very nice oscilloscope app. I like the Wifi settings like the AP setup. Now it is possible to operate wireless, away from home, without the internet router.
