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.

More information
More information including instructions for installing the free firmware onto your Pico or Pico W can be found here: https://github.com/fhdm-dev/scoppy and https://oscilloscope.fhdm.xyz

Wow! The new updates to 2Msps sampling are amazing! I have been using Scoppy for two years and really liked it, but to get a 4x upgrade in sampling rate as a software upgrade is awesome! The other upgrades over the past two years have been great, too! I really like the flexibility to assign functions to arbitrary pins and to customize voltage ranges based on the design of the front end of the scope. Scoppy was great before, but now it's awesome. Awesomer. And it just keeps getting better!

This is the best software for pi pico. And it's free too. I loved it so much that I actually bought it's premium. This was the first time that I expend money on any app. Truly mind blowing app who loves electronics. Now I don't need expensive oscilloscope to test my waveform. This can do same job but in nominal price.
