just following a tutorial on YouTube [https://www.youtube.com/watch?v=Ko0heNZhRvI], for setting objects in lab-view for simulation, doing the steps as stated. as program executes, the resultant spheres, ( which has been added to the 3D picture object, are very far out zoomed ) , done the following steps to correct it, still no help
1) seen online help of using "shift + drag" to correct it, but it's still no help,
2) changed camera position to : none and auto - redraw, still no help,
since i am new to this, it is request to state the measure to correct the problem and to avoid these problems.
Along with one question : how to add Co-ordinate axises for reference to it, independent of any other objects, [ i.e. the axises shouldn't be affected by rotation, translation or objects ] in 3D picture object
edit : same question is posted as well on : https://forums.ni.com/t5/LabVIEW/camera-postion-stuck-in-3D-picture-control/m-p/3990030#M1138526
Manufacturing a satellite or a simple pen require to test the quality of the product before delivery to the customer.
LabVIEW is widely used for that purpose. Since 20 years of LabVIEW development I saw numerous test framework. I was wondering if people where interested to work in a collective and open source test framework.
Per example the following feature can be included:
HAL (hardware abstraction layer)
Database to record test results with the data viewer (PostgreSQL)
Image analysis (open CV) + bar code reader
User access level
Jig identification to prevent user error (testing the wrong product with the wrong jig/test sequence)
and so on....
I've been maintaining and improving a LabVIEW project which controls and automates a prototype microscope array for 2 years. I'm an engineering apprentice so I don't have that much experience with LabVIEW.
The current framework of the project is a simple "Producer/Consumer" which has served well but is no longer future proof and scalable. I want to revamp the program which is quite big and complex. And I need help since this will be the first time of actually starting a real project from the ground up.
The most modular and scalable framework I found was the QMH (Queued Message Handler). It's similar to the basic P/C loop and has the possibility to have multiple parallel consumer loops. But I have no experience on starting from 0.
If any you have docs or give advice on starting the project would be appreciated. Especially something on codding with a QMH structure would be helpful.
Cheers from France!
Hi LAVA friends,
We are pleased to announce that the Delacor Queued Message Handler (DQMH) is now available via the LabVIEW Tools Network:
You can read about the thought process behind DQMH at our blog post: Ours is not better than yours (or YAF=Yet Another Framework) at WalkingTheWires.com
The DQMH is based on the NI QMH Project Template. The DQMH expands on the NI QMH by providing safe, event-based message handling and scripting tools to encourage same style between different developers in the same project and improve efficiency. The DQMH is ideal for applications where multiple modules must run in parallel, possibly at different rates, while communicating with each other. The DQMH can also be used for applications that have a single module, where the developer would benefit from having a Tester with the capability of eavesdropping on the different DQMH events and messages.
The DQMH integrates with TestStand since all development and troubleshooting can take place under LabVIEW, while calling the public API VIs as individual steps in the TestStand sequence. The tester can eavesdrop during the execution of the TestStand sequence. This is specially useful when the LabVIEW code is written during the research and development or prototyping phase, because the same code can be called by TestStand in production or manufacturing sequences without any changes.
The DQMH uses LVOOP for some internal functions, but developers need not be familiar with LVOOP to use or understand this architecture.
Try it out and let's us know what you think.
Fab and the Delacor team.
