Overview

This VI writes a basic concatanated string to a text file on an external USB drive connected to the USB port of an NI cRIO controller, however, should be applicable to the majority (if not all) NI RTOS controllers    

 

Description

This VIS take a basic "Hello World" string, concatanates it with a Comma, and then writes it to the USB drive connected externally. The address is simply u:\ and then the name of the file.

IMPORTANT - The USB stick has been formatted to FAT32

 

Requirements

Software

LabVIEW 2013 (or compatible), LabVIEW Real-Time Module

Hardware

I used a cRIO 9025, however, any RTOS controller should work

USB Drive Formatted to FAT32

 

 

Steps to Implement or Execute Code

  1. Place VI under RT component of project
  2. Set fil name in file path
  3. Run
