Hi, I can develop the LabVIEW curve tracer around Digilent’s official AD2 SDK, using a maintainable QMH/state-machine architecture for sweep control, acquisition, live plotting, and CSV export. I’ll make voltage limits and step size configurable, support both resistor and LED measurements, and validate the captured I-V curves against WaveForms using the same hardware and sweep conditions before delivery. A few questions: * Which LabVIEW version and operating system will run the VI? * Are you using the official Digilent WaveForms SDK directly or WaveForms/NI-VISA integration? * Should current measurement use an external sensing resistor or another AD2 measurement method? Best regards, Muhammad Usman

Build a LabVIEW curve tracer that mirrors Digilent WaveForms behavior using Digilent’s official Analog Discovery 2 SDK. The executable VI will sweep a configurable voltage range (limits + step size), sample current/voltage during each step, and render a real-time I‑V plot. Architecture will be maintainable and responsive via a clean state-machine (QMH-style) coordinating: sweep setup → acquisition timing → point buffering → live plotting → export. Export will be built into the GUI with direct CSV output for immediate Excel/MATLAB workflows. Implementation will support resistors as the primary test case while remaining flexible for simple LED measurements by allowing user-defined scaling, sweep boundaries, and acquisition settings. GUI will include voltage-sweep controls, status/progress indicators, live plot, and an Export CSV button. Deliverables: complete LabVIEW project with documented block diagrams and an executable VI ready to run, plus proof-of-function materials captured from real Analog Discovery 2 hardware showing at least one resistor trace and one LED trace, with timing tuned to match WaveForms for the same sweep.

@alluankit01

Hi, I can build your LabVIEW-based curve tracer for Analog Discovery 2, matching Digilent WaveForms-style behavior with configurable voltage sweep, live I-V plotting, resistor/LED testing, and CSV export from the GUI. The best solution is to first define the AD2 SDK communication flow, voltage sweep limits, step size, sampling method, current calculation, and export format. Then I’ll build a clean LabVIEW state-machine/QMH-style application with front-panel controls, real-time graph updates, device selection, error handling, and maintainable documented block diagrams. I’m comfortable with LabVIEW, Digilent Analog Discovery 2, WaveForms SDK integration, data acquisition, voltage/current measurement, signal processing, I-V curve plotting, CSV export, GUI design, state-machine architecture, and hardware validation. Deliverables will include: * Complete LabVIEW project * Executable VI ready to run * AD2 SDK communication setup * Configurable voltage sweep * Resistor and LED test support * Real-time I-V curve plot * CSV export from GUI * Documented block diagrams * Error handling and user controls * Proof-of-function demo/video I’ll focus on functional parity with WaveForms, clean architecture, accurate measurements, and easy data export so you can validate the traces directly on your AD2 and use results in Excel or MATLAB. Best regards Ankit

@miguelcen64

Absolutely , I can build this as a clean, maintainable LabVIEW application that mirrors the WaveForms curve-tracer workflow while running entirely inside LabVIEW with the Analog Discovery 2. I’d implement a state-machine or QMH architecture with a responsive front panel for sweep setup, live I-V plotting, and one-click CSV export directly from the GUI. The measurement flow would use Digilent’s official SDK for tight, reliable communication with the AD2, and the sweep parameters would be fully configurable so you can move quickly between resistor tests and LED forward-voltage measurements. To support your acceptance criteria, I’d also include documented block diagrams, an executable VI, and a short proof-of-function demo showing at least one resistor and one LED measured on real AD2 hardware. The goal would be functional parity with WaveForms behavior, with clean code you can maintain and extend later. If helpful, I can structure the project so the sweep engine, acquisition logic, plotting, and export layers are separated cleanly for easier validation and future upgrades. Miguel

@HamparProd

Hi, I can build the LabVIEW curve tracer around the Analog Discovery 2 using Digilent’s official DWF SDK, with the application structured as a maintainable state machine/QMH rather than a monolithic VI. The front panel will provide configurable sweep start/end voltage, step size and timing, live voltage/current display, real-time I-V plotting, run/stop controls and direct CSV export for Excel/MATLAB. I’ll keep acquisition and hardware control separated from UI logic, with proper error handling and device initialization/cleanup so repeated sweeps remain reliable. The implementation will support resistor characterization first, while keeping the sweep logic flexible enough for LEDs and similar simple devices. Current calculation, scaling and sampling will be validated against the same component measured in WaveForms. Delivery includes the complete LabVIEW project, documented block diagrams, executable VI/build instructions, CSV export, and a demonstration using resistor and LED traces.

@ahmaddar2970

Thank you for the opportunity. I can build this as a clean LabVIEW application using a maintainable state-machine or QMH structure, with Digilent’s official SDK handling all Analog Discovery 2 communication. I’ll implement: - Configurable voltage sweep limits and step size - Real-time I-V plotting for resistors and simple LED measurements - GUI controls for setup, live trace viewing, and one-click CSV export - Documented block diagrams and a runnable executable VI - A demo workflow that shows both a resistor and LED capture on AD2 hardware The focus will be functional parity with WaveForms behavior on the same device, while keeping the code organized, reusable, and easy to extend. The export path will be built directly into the front panel so results can go straight into Excel or MATLAB without extra scripting. If helpful, I can also structure the project so future device profiles or measurement modes can be added with minimal changes. Ready to proceed.

@Alexwebo23

Hi You're looking for a LabVIEW curve tracer that matches the functionality of the Digilent WaveForms and connects smoothly with your Analog Discovery 2. The crux here is building a real-time I-V curve plotting system with customizable voltage sweep parameters. I'll leverage LabVIEW's capabilities and Digilent's SDK to ensure precise timing, akin to what you experience with WaveForms. I've previously developed LabVIEW applications for data visualization and signal processing, focusing on real-time performance. Utilizing techniques like state-machine or QMH, I'll ensure this project remains robust and maintainable. Your choice of making the interface intuitive and as informative as WaveForms resonates with me—I appreciate well-designed, user-friendly software. I can help bring this project to completion and would be glad to walk you through the planned approach or any specific details. Thanks, Oswaldo

@HiFiDesigner

Hi there, Testing components like resistors and LEDs in LabVIEW often suffers from noisy I-V traces, timing skew, or buffer misalignment between the WaveForms AWG sweep and scope acquisition. The main priority isn't just plotting a line on a front panel—it's securing tight SDK-level hardware synchronization so your LabVIEW measurements achieve exact functional parity with WaveForms without baseline drift or missing step data. I recommend a Queued Message Handler (QMH) architecture built around Digilent's official C-SDK: • Synchronized Hardware Loop: Direct SDK calls to drive the AD2 Wavegen sweep while synchronously sampling Analog In channels, guaranteeing clean, drift-free I-V curves for both linear resistors and non-linear LED forward-voltage sweeps. • Configurable Parameters & Fast Export: Front-panel controls for variable voltage limits, step resolution, and averaging, paired with a one-click CSV export engine formatted directly for Excel or MATLAB. • Maintainable Delivery: Clean, modular block diagrams with strict error handling, executable VIs, and a proof-of-concept video verified on physical AD2 hardware before hand-off. I’ve engineered LabVIEW test systems integrating Digilent and NI hardware SDKs with custom state-machine GUIs, achieving sub-millisecond loop sync and exact vendor software trace parity. Send over your target sweep ranges or current setup details, and I’ll outline the QMH architecture and SDK wrapper plan for your review.

@ianb65

Hello, Your LabVIEW curve tracer needs WaveForms-level behavior on the Analog Discovery 2, with clean exports and real-time I-V plotting. I’ve got strong expertise in Data Visualization, LabVIEW, and Signal Processing, and I can build this as a maintainable QMH/state-machine app using Digilent’s official SDK. I’ll implement configurable sweep limits and step size, sample voltage/current tightly on the AD2, render the live curve on the front panel, and add reliable CSV export directly from the GUI for Excel or MATLAB.
