  1. Adding to crossrulz suggestion. If you do want simple I2C or SPI, using an Arduino is a great solution in LabVIEW. NI has their LINX toolkit, which downloads a known set of firmware to the Arduino, and then in LabVIEW you have the LINX palette which basically tells the microcontroller to execute some set of steps. These commands are just serial commands, and when plugged into USB should appear as a normal VISA device in LabVIEW. I don't have a pharlap system to test with but with other remote devices I've used they just get enumerated when they are plugged in. I personally have not us
  2. If you are just trying to replay the message you already have from a valid log you can do that and see if the ECU is happy. Was it possible that it was setting DTCs when the log was recorded? If you want to change any bit inside the payload you'll need to figure out the algorithm used. As we said it clearly isn't the standard one used for CAN. Other than just guessing a bunch of things I don't think you'll be able to get past this issue. That is again unless all you want to do is replay a already recorded log. Also here's a random thought. Are you sure that byte is a CRC at all? I
  3. I don't think so, it won't work outside of a project anyway since that conditional value is only going to be available in a project that has that value.
  4. I've seen that some cases the symbols shown are only pulled in from the target that is listed under the project. Did you happen to open this from a blank VI or a new project? Anyone can add additional symbols, and NI adds a few when you add certain targets to your project. You can view these by going to the properties of the target from the project.
  5. Yeah what Rolf said. I've seen several CAN payloads with a message counter, and CRC, and never has there been any meaningful data after the CRC. I have seen times when it is an 8 byte payload, and the 7th byte is the CRC. But in this case the 8th byte wasn't used in the CRC calculation. You can find the typical J1850 CRC calculation online here just set the Predefined to CRC8_SAE_J1850. After playing around for a little while I couldn't get the CRC byte you provided to match. If you do ever figure out the algorithm, there are a couple of options on how to do this in XNet. Obviously
  6. How about something with the File IO? Maybe copy all files and folders from one location to another and list the files that were new or overwritten? Maybe open a text file with times and values in it then graph it? Maybe import a text file into a table and color the values that are greater than some value red, and lower than some value green?
  7. So one thing that might help make it click, is that objects aren't reference based by default. So you are initializing an object, adding an axis, and then passing that data into a loop. The data that the loop uses each iteration, does not change it is the same data over and over again. However if inside that data is a reference to something, then that something can change, and the reference doesn't. But that feature is only used if the developer of the class used references in the private data of the object. The class data can be thought of as a cluster (because it is). So imagine if
  8. Here is a VI that gets the title of the window that is active. You could then continually loop until the title you expect is active, then perform operations. https://forums.ni.com/t5/LabVIEW/Get-Current-Active-Window/m-p/3930389#M1116926
  9. What part are you having problems with? Many VIs and controls are missing, and this is clearly school work.
  10. There are several libraries online for simulating keyboard presses and mouse interactions. https://forums.ni.com/t5/Example-Code/Programmatically-Simulate-Key-Strokes-in-LabVIEW/ta-p/3521756?profile.language=en https://forums.ni.com/t5/Example-Code/Using-LabVIEW-to-Simulate-Keyboard-Events/ta-p/3996210?profile.language=en https://forums.ni.com/t5/Example-Code/Simulate-Mouse-Click-on-a-LabVIEW-control/ta-p/3509840?profile.language=en
  11. I think this was mentioned in the video I linked to. I was just thinking about how much work the stunt coordinator, and stunt men had training and planning for a thing that just never happened. It probably happens a lot in the film industry but as someone in the digital world I tend to keep even the work that I never actually use.
  12. It was but does give us some character development. Showing the exhaustion on his face, and surrounded by dozens of people that might attack. He kinda is like, nah I'm done I got other things to do. Also likely considered murder since it would be difficult to claim self defense.
  13. Love it. BTW here is a crosspost on the dark side.
  14. I've heard conflicting information on this one. Here is a quote from another champion: Also mentioned in this private conversation was a thunderbolt to PXI chassis from a 3rd party that I don't have experience with https://www.adlinktech.com/Products/PXI_PXIe_platform/PXIChassis/PXES-2314T?lang=en
  15. Yeah I'd suggest looking into MXI. In particular I've used the PXI chassis that has MXI integrated into it. I'm pretty sure it was the PXIe-1073. This is a 5 slot PXI chassis, that can come with a cable and PCI card included. (Be sure and get the right part number if this is what you want). With this you can plug the PCI card into a compatible desktop PC, and then it will see the PXI chassis and all the devices in it in MAX. Great for when you need to expand a PC to have a bunch more channels, or cards that are only in the PXI form factor. Oh and if you have the chassis already, NI sells
