LINX is an open source project by Digilent and is designed to make it easy to develop embedded applications using LabVIEW. LINX includes VIs for over 30 of the most common embedded sensors as well as hardware agnostic APIs for accessing peripherals like digital I/O, analog I/O, PWM, I2C, SPI, and UART. Whether you’re remotely controlling a chipKIT or Arduino over USB/Serial, Ethernet o. LArVa - Labview Arduino - Simple Graph Application. The Simple Graph application is a Labview program that uses the Labview Arduino Driver (LArVa) to gather between 1 and 6 channels from your Arduino microcontroller and display them on a graph. The program allows you to save the raw data and access the full capabilities of the LArVa driver.

Step: 01Introduction to LabView:

Labview is an advanced tool for Engineers and industrial applications.The LabVIEW is an integrated development environment designed specifically for engineers and scientists building measurement and control systems. Labview is effective simulation software that can simulate lab tasks, equipment, and industrial complexity.It simplifies the complexity.Use an intuitive graphical programming syntax that was designed for the way an engineer maps thoughts to code.

Labview has First-Class Hardware Integration.It acquires data from any measurement hardware over any bus.

LabView rapidly develop user interfaces for data visualization and user input with an easy-to-use drag-and-drop interface.One more feature discussing here is Extensive Analysis and Signal Processing IP Develop algorithms for data analysis and advanced control.These are the common features of Labview.We can perform more tasks related to our projects.The best thing we can easily control everything from the simulation.

Step: 02How to interface Arduino with LabView:

Arduino is the best open source hardware tool.we can easily interface control and simulate our hardware LabViewiew. (E.g): we have to control the speed of motors or we have to make a binary logic conversion on, we just have to make some simple block diagram programming on LabView. So we don’t need to perform any Arduino coding and conversion relations.These are the basic examples. we can control measure and perform many difficult tasks using LabView.The Arduino projects can be easily controlled and monitored through LabVIEW.

For interfacing Arduino with Labview, we have to install some drivers, makerHub libraries, and VI package manager. These are few simples installations steps.

First You have to do these four installations:

Download from the links below or from any other source:

01LabVIEW 2016 from this link

http://ftp.ni.com/…/other/down…/2016LV-WinEng_downloader.exe

02Download NI VISA drivers from this link or search it from anywhere if this link show error:

http://ftp.ni.com/…/so…/visa/NI-VISA/5.2/win/visa520full.exe

03Download and install VI Package Manager from this Link

https://vipm.jki.net/download

04After installing VI Package manager, open it and in search bar type “LINX” and install the LINX makerHub library.

After installing all these libraries Open the Labview and follow the following steps:

Go to files>open New VI

The two screens will be open up, One is Control panel and other is block diagram:

Go on to the tools of any window>MakerHub>LINX>LINX Firmware wizard.
This window will open up:

Connect your Arduino board to the Port before this step:

Now choose the Device type: your Arduino board >click Next>Choose serial port>Next and Finish.

It will burn the pre build Hex.and then click on Finish.After these steps come back towards the two windows Control panel and Block diagram.Now everything is ready for you to build and test.We will see Examples in next tutorials.

Step: 03Activation of Labview

Labview is a Ni instruments Software.The activator is free and for a lifetime.
You can download from anywhere.

Open the activator >check the boxes>the boxes will turn green>select the desired activation file and go to files or Right click and click on > Activate

It will Activate.Now Enjoy.
You can also Generate a serial key for any Ni desired product by clicking on generating the serial key.

A quick post about wiring TB6600 stepper driver which is based on TB6600HG chip. Here I use one without black plastic casing. It has model marking on the back that says “BL-TB6600-v1.2″. Stepper motor used in this demo is 23HS22-2804S (2.8A, NEMA23). Drive looks like this and it’s rated for 4.5A.

Looking for more info and photos? Check out my previous post about TB6600 drive where I removed heatsinkFree xbox full game codes. covering the whole PCB.

Wiring TB6600 and Arduino

Terminals on the drive are clearly marked and there is nothing much you can go wrong with. Power supply should be between 8V to 42V (by chip’s datasheet). Low voltage cut-off was actually around 6.5V when I tested it. You have to find paired wires of your stepper motor and connect them to drive’s A+ A- and B+ B- terminals. From Arduino, I had to connect only 3 wires.

Arduino +5V to +5V on the drive
Arduino Digital pin 9 to CW (direction) on the drive
Arduino Digital pin 8 to CLK (pulse, step) on the drive

I left enable pin disconnected for testing.

If you are a beginner and want more in-depth info – check out my other post on how to drive a stepper motor.

Programming Arduino

I used AccelStepper library to make the motor run smoothly for testing. The program I used was Bounce which is one of the example code snippets from that library. Here is the final Arduino sketch I used to make the demonstration video at the end.

TB6600 microstepping settings

Note about dip switches on board. When I hooked everything up for the first time- I didn’t get it working. I was bit confused. That happened because I had all dip switches in off state. I thought that if everything is off- there is no microstepping applied. But with TB6600 it means the drive is disabled. Here is a screenshot from the datasheet for quick reference. Grab the whole datasheetfrom here.
