Simple UDP Protocol in Labview | Receiver | Transmitter | loopback on Localhost IP | Step-by-Step

Welcome to Tech Xort — your hub for FPGA, DSP, and embedded system tutorials!

In this video, you will learn how to implement a simple UDP (User Datagram Protocol) communication system in LabVIEW, including both transmitter and receiver configurations using localhost IP (127.0.0.1) for loopback testing.

This step-by-step tutorial explains how to create a UDP sender to transmit data packets and a UDP receiver to receive and visualize data in real-time, all within a single PC. The loopback setup makes it ideal for beginners to understand UDP communication without requiring external hardware.
