Steadily rising memory in a long-running LabVIEW VI or executable is not always a leak. Use these ordered checks to separate true resource leaks from redraw overhead and fragmentation.
When a LabVIEW VI grows to dozens of states, the choice of how to manage them matters. Using an Enum in a While‑Loop‑Case structure gives type safety, readability, and easy scalability. Learn how, why, and what to watch out for.
Guide for choosing LabVIEW Event Structure vs. polling loop when acquiring 1 kS/s data with ≤1 ms latency and <30 % CPU usage on a real‑time target.
Learn how to identify and fix consumer starvation in LabVIEW Producer-Consumer architectures to prevent memory exhaustion and UI freezes.
The Actor Framework offers a hierarchical, message-driven architecture that isolates subsystems, automates error propagation, and simplifies shutdown. This post walks through core concepts, a concrete example, and when the extra complexity pays off.
A frozen front panel during DAQ acquisition is a structural problem, not a tuning problem. The Queued Message Handler fixes it by separating UI events from slow work — here's the shape, a worked logger example, and the trade-offs.
Actor Framework replaces shared-variable race conditions with message-driven actors. Here's when to adopt it, a temperature-monitor example, and the overhead you'll pay.
Step‑by‑step guide to building a LabVIEW Producer/Consumer VI that uses queues to decouple acquisition from processing, with checks, shutdown options, and limitations.
Identify why a DAQmx acquisition VI appears frozen, check error codes, buffer settings, task cleanup, loop timing, and timing source, then apply targeted fixes or escalate to NI support.
