Enter the Raspberry Pi Pico. For less than $10, this tiny microcontroller can be transformed into a powerful 8-channel logic analyzer thanks to an open-source project called . The magic happens through a single file: pico-scoppy-v8.uf2 .
You can download the official release from the project’s GitHub repository: pico-scoppy-v8.uf2
While the file is named pico-scoppy-v8.uf2 , the hardware supports analog reading via a simple voltage divider. To use the oscilloscope function: Enter the Raspberry Pi Pico
Essentially, is the brain transplant for your Pico. Without it, the Pico is just a generic microcontroller. With it, the Pico listens to digital pins and waits for commands from the Scoppy Android app via USB or Bluetooth. pico-scoppy-v8.uf2
