VIWeek

VIWeek

Due to the cancellation of live, in-person events from NI, Steve Watts, with other LabVIEW Champions and Community leaders started the idea of a new community-led virtual event. You can see Steve's blog here with the current agenda.

Visit the VIWeek Portal at https://bit.ly/viweek for the full agenda. (Also see how to connect to the individual sessions.)

Introduction to VIWeek from Chris Cilino

Event Recordings:

• This area will be populated with post presentation materials and links to video recordings as they become available.

• GCentral: State of the Union and Rolling Up Your Sleeves by Chris Cilino and Danielle Jobe

  GCentral is a non profit organization founded in late 2019. The vision: a LabVIEW community empowered to make the best version of itself. The mission: reduce/remove barriers to collaboration. In this presentation, we'll introduce you to GCentral and give a progress update. And we'll show you how we can all work together to make GCentral a reality.

• LabVIEW FPGA for high throughput applications by Terry Stratoudakis
• Functional programming inspired object-oriented template in LabVIEW + SOLID by Piotr Kruczkowski (LinkedIn Article)

• DSH #VIWeek Pragmatic SW Engineering by DSH Gang: Fabiola De la Cueva, Steve Watts, Joerg Hampel, & Brian Powell

  Join us and fight the NIWeek blues. In this one-hour event, we (the whole DSH gang: Fab, Steve, Joerg and Brian) will be:
  - talking about who we are and what we do
  - asking you about your needs and pain points
  - answering any questions you might have

• Philosophy of Coding - How to be a CraftsPerson by Sam Taggart

  A discussion of how what we value and the way we think about the process of developing software affects the end result. No LabVIEW code, just a high level discussion of software engineering. I've got a short presentation on our values at SAS and how we approach software development. I'll give that and I'd like to get some feedback. Then I'd like to have a discussion and ask the audience some questions like, what software qualities are important to you? What processes do you think are critical to ensuring software quality? What quality is most important in a junior engineer? How can we do a better job of training junior engineers?

• Confessions of a Retired Superhero by Matt Pollock

  Crazy projects demand crazy solutions. Crazy solutions create crazy bugs. Come learn from spectacular failures (or near failures) that have threatened to torpedo other projects so yours will be safe from heroics.

• Proper way to communicate over serial by Tim Robinson

  Too many users look to the Simple Serial Write Read example in LabVIEW and then struggle to achieve solid, robust communication with their instrument. This is because the example does not properly discuss or handle any of the real-world communication schemes instruments use. At this session, explore these schemes and learn how to handle each case.

• Raspberry Pi / LABVIEW CE and Sensors by Sam Sharp

  Sam will demonstrate/show how to get started programming the Raspberry Pi using the LabVIEW 2020 Community Edition with a live/practical demo. He'll then expand this to show off his open-source library of drivers for a range of off-the-shelf sensors/hats so you can connect your Raspberry Pi to the physical world.

• Linx Toolkit for Intermediate Robotics with Raspberry Pi by Derrick Bommarito

  I'll be demonstrating how I've used the updated Linx Toolkit for LabVIEW Community Edition to develop remote control and autonomous rovers using the Raspberry Pi along with a handful of sensors. We'll take a look at the high level architecture of the software along with the open source libraries I'm developing that target autonomous robotics projects. We'll also discuss how you can accomplish better performance for more demanding projects by developing custom firmware for arduino clones instead of using the Linx toolkit to interface to microcontrollers.

• FPGA Advanced Sessions to create a versatile FPGA-based acquisition system by Cyril Gambini
• 8 Reasons for encapsulating your next device driver inside a DQMH module by Christopher Farmer

Wednesday, 20^th May 2020

• DSH DQMH 5.0 Introduction by DSH - Fabiola De la Cueva & Hampel

  Hear it directly from the horse's mouth! Learn what's new in DQMH 5.0. In this one-hour event, we (Fabiola and Joerg) will walk you through the new features of DQMH 5.0. We'll also give insights into how these features actually help with our daily work.

• Efficient Programming in LabVIEW by Tom McQuillan

  In this session, I'm going to showcase Project Templates. After choosing to go down a DQMH route for a project (after being a hardcore Actor Framework user), I realized there were certain aspects of AF I missed. Namely, the ability to reuse messages between modules. In this session, I will showcase a solution to this using Project Templates and how templates could be used for your modular applications. I'll also showcase some scripting tools that were possible using templates.

• Using a Message Broker with DQMH Actors for High Speed/Throughput Data logging by Chris Roebuck and Becky Linton

  Tasked with creating a hardware agnostic, highly configurable, high-throughput data logger for ADAS applications we implemented the Mediator pattern using multiple modified-DQMH actors with a message broker. In this session we will review the requirements, high level design objectives and review the solution and take a deeper dive in to some of the specific technologies used such as malleable VIs, eDVRs and Message Brokers.

• Graphical programming beyond G - Use case of LabVIEW inegration with Node-RED by Michal Radziwon

Thursday, 21^st May 2020

• CEF (configuration editor framework) by Sreejith Sreenivasan & Vikas Koujalagi

  Configuration files are commonly used to specify application settings and hardware configuration. Manual editing of some of the complex configuration files of hardware systems or applications are often error prone. Shipping a configuration editor can ease the pain but development overheads may outweigh the benefits. Configuration Editor Framework (CEF) from NI Systems Engineering is a versatile framework allowing rapid development of such editors. Development generally take hours instead of days or weeks. This presentation delves in to the features and walks through an example which saves the files in JSON format.

• Using the new TLS/SSL functions in LabVIEW 2020 by Sam Sharp

  Sam will go through the newly added SSL/TLS functions in LabVIEW 2020 which enables secure TCP/IP communications in LabVIEW. This session should provide enough information to be able to implement secure TCP/IP communications in your own applications and learn why you should. He'll also demonstrate an update to his WebSockets library that enables secure WebSockets (wss://) support - a highly requested feature now possible with LabVIEW 2020.

• DSH Soft Skills for Software Engineers Discussion by DSH Gang: Fabiola De la Cueva, Steve Watts, Joerg Hampel, & Brian Powell

  Bit of a chat

• #VIWeek – Open Your Instruments With A G Interfaces HAL In LV2020 (No Lever Tool Required!!) by Jonathan Hird (Jono)

  PThe recent release of LV2020 Community edition has opened up the new capability of “Interfaces” into the LVOOP world. I for one am incredibly excited about what this means specifically for Hardware Abstraction Layers. After some initial trudging through the mud and not quite seeing the value in interfaces for my specific needs for a HAL, I decided to scrap what I had, start from scratch and work logically to put together an example of a “Real World” HAL application. In this session we will briefly cover the Why, What and How of HALs and how interfaces may help along with some sample code which will be uploaded for community use as a good starting point.

• The Core Framework by Denis Stavila

  It's something that I built on top of the Actor Framework and aims at solving several shortcomings that I believe AF has ... plus a lot of tweaks and built-in functionality to make the life of a developer much easier: - Internal broadcast system - Debugging/Monitoring tools - UI structuring and configuration - User Access tools .... etc.

• Mock Object Framework by Sam Taggart

  I will present an open source tool for creating Mock objects and show how to use them in tests. It will be an informal kind of code review thing. I might put together a few slides on what Mock Objects are so we are all on the same page. After that I will just start with defining the problem and then how I came up with the solution. We will spend a lot of time just looking at the code.
