<html><body>DuinoScope GIGA R1: Dual-Channel 1Msps Touch OscilloscopeIntroduction The Arduino GIGA R1 WiFi is a powerhouse of a board, sporting a dual-core STM32H7 microcontroller and two independent high-speed 1Msps ADCs. Combined with the Arduino Giga Display Shield (a high-resolution 800x480 screen with multi-touch support), it becomes the ultimate platform to build a fully functional, standalone digital oscilloscope. DuinoScope is a high-performance, dual-channel digital oscilloscope designed to exploit these hardware capabilities. It features an interactive on-board capacitive GUI, dynamic touch gestures, and a local WiFi Access Point that lets you remotely monitor and control the scope from any smartphone or tablet browser. <h3>🚀 Key Features</h3><ol><li>Dual-Channel Trace Acquisition: Measure two independent signals simultaneously on <code class="code">CH0</code> (A0 - Yellow trace) and <code class="code">CH1</code> (A1 - Cyan trace). </li><li>High-Speed 1Msps Sampling: Uses optimized DMA buffers through the <code class="code">Arduino_AdvancedAnalog</code> library to capture waveforms in real-time. </li><li>Interactive On-Board UI: A modern on-screen dashboard built with LVGL v8.3.11 featuring pinch-to-zoom for Timebase scaling and vertical dragging for trace offsets. </li><li>Local WiFi Access Point: Creates its own hotspot (SSID: <code class="code">DuinoScope</code> , Password: <code class="code">12345678</code> ) with a captive portal that automatically redirects connected clients to the controller web app. </li><li>Real-Time Web Dashboard: A responsive, dark-mode web panel that streams live telemetry data including Frequency (Frec) , Peak-to-Peak Voltage (Vp-p) , Vmax , and Vmin for both channels, while allowing you to control scope settings remotely. </li><li>Analog Front End (AFE) Compatible: Built-in digital control pins (3, 4, 5, and 6) to select input attenuation ranges on an optional AFE daughterboard like the <code class="code">Fscope-500k </code>for wider voltage range tolerances. </li><li>RGB Status Indicator: High-performance software PWM-driven status LED showing network activity (breathing blue when disconnected, solid when connected) and input signal tracking. </li></ol><h3>🛠️ Hardware Requirements</h3><ol><li>Arduino GIGA R1 WiFi board </li><li>Arduino Giga Display Shield </li><li>(Optional) Fscope-500k AFE board (for handling negative voltages and 10x probes) </li></ol><h3>🌐 How to Use the Web Panel</h3>1. Turn on the DuinoScope GIGA R1. 2. From your mobile phone, connect to the WiFi network DuinoScope using the password 12345678 . 3. Open any browser and go to <code class="code">http://192.168.3.1/ </code>(or let the Captive Portal page pop up automatically). 4. Monitor live telemetry measurements and configure scale divisions, timebase, and trigger thresholds directly from your device. <h3>📂 Code and Repository</h3>All source files, compilation guidelines, and hardware schematics are open-source and hosted on GitHub.
