scopy

Scopy is a lightweight DIY oscilloscope built on the ESP32.

Overview

• ESP code (scopy_main.c): Reads ADC and prints values to serial.
• Python main (main.py): Reads serial data in real-time and plots it.
• Python viewer (scripts/view.py): Loads previously dumped CSV data and displays it graphically.

Features

• Real-time ADC reading and plotting.
• CSV logging for offline analysis.
• Dedicated viewer script for inspecting dumped data.

Prerequisites

• Python 3.10+ recommended
• ESP-IDF for building and flashing the ESP firmware
• Serial connection to the ESP device
