  1. Hello Mike, It's been a while I created this library. I was never a big fan of the file function. So I never used it. I am afraid you will have to do some coding and research. Benoit
  2. OK I see... so i am still stuck without solution. since my matrix is not complete, and there is no extrapolations, The only thing i found is the point like this... It's better than nothing
  3. Hi, I can't understand how 3D graph are working. What I am trying to do is to plot multiple point XY with a Z as intensity of the measurement. I was expecting a x,y,z coordinate, but 2D for the Z... I just don't picture how it works. I got a half sphere with sensor. I am trying to represent in 3D X,Y the position of the sensors as a flat position ignoring the Z and using the Z for the sensors values. Please help.
  4. I am sorry, but I do not have access to LabVIEW anymore. I can't do any conversion.
  5. I never tried it without installation of the driver. in some case it might work like the serial port version. Benoit
  6. I think you posted in the wrong place. But there is where to start. Install the firmware in your Arduino +shield (Need to be GRBL 1.1) Then using the toolkit, you can control the XYZ plotter by giving the coordinate. This is not a G code interpreter, it is a tool to control the position of the XYZ.
  7. The sequencer that you use is it TestStand? Actually, The design I did give me more advantage than what is offer by NI. so no... I wont design it differently. When I want to add a Power supply model/manufacturer into the list, I have to modify only the middle lever of the HAL by adding a case in the list of every function. that case hold the driver from the manufacturer(LabVIEW,.dll or other) I can't show you by video right now. Not sure my company will allow me to do that. In the case of your sequencer, I believe that no other software will call your driver... I think that you
  8. The call is done by the following step. Init: create a reference on all the function "VI" for that instrument. (keep in a getset) Function call: from get set use the reference of the function to send parameter or get parameter of the instrument Close: close all the reference from the getset In the .exe that holds all the Instrument, I have every instrument function in separate re-entrant VI. The physical init to the instrument and physical close instrument in done by the executable not by the caller. This allow the caller to have the status of the instrumen
  9. Here is the problem. When displaying in a Hex format, the update value while typing cannot be activated. Since the value is updated only when you click somewhere else on the front panel, if the first click is on the button COM Write, the value is updated after the Event mouse down is fired. Benoit
  10. For my part, I use VI server call per function per instrument. The VI that is dynamically is in another .exe. This .exe has all the driver for all the instrument. the instrument selection and availability is done trough a .ini file. currently I support 22 different hardware like JTAG, Eload, PSU, Hipot, I2C CAN bus, SPI, Oscilloscope, Switch, DAQ, Ethernet, serial port, etc... Each instrument type support multiple manufacturer and model. When a call is done by VI server, the capability of the selected instrument is evaluated and report an error if out of range. Th
  11. Yes, with a robot and a finger simulation hardware. Benoit
  12. Please post your actual VI. This will allow us to see if there is race condition or other problem. Thanks Benoit
  13. Amazing VI, but very slow. It takes many second to parse 2 Mb of Data. Is it possible to make that multiple processing in some way? I cannot find another encryption that will work with the input and output of those. Did you follow 100% the standard? Thanks Benoit
  14. A simple solution for you would be to work with a copy of the project and then whatever you want except deleting... then no crash and you project original remain clean... by the way, project and library are only .xml files. Benoit
  15. You might have some VI that are not saved may be read only that reference a VI in that folder even this VI do not exist... The question is why those virtual folder are empty? what is the last action before? It is possible that you deleted library as well that where on those virtual folder.
  16. Are you sure it comes from that VI? As I understand this VI is called with different function on every call. the one that will be called the most will be "Log Data". So I strongly suggest to create a unit test with your VI called multiple time with this function to validate if the leak comes from there. But I am pretty sure not... What the rest of you project is doing? Other question... what is the file size generated? Benoit
  17. I'll say that you understand how to add a value to make it move, but for the rest, the architecture need to be revised. Look at the example i suggested you. Benoit
  18. Look at the LabVIEW example Dynamic Event Generation.vi And learn LabVIEW basic. I cannot give you all the answer to easily, where will be the fun to learn LabVIEW. Benoit
  19. After the sin and cos, add or subtract a number of you choice. To make it live, use a event structure in a while loop. Benoit
  20. Hey guys, Can you take a look at this? The only work around I found is to dynamically open the connection with an external VI to make it fail so the second time it works. If anyone has an instrument that communicate trough TCP-IP with VI, please try on your side with LabVIEW 2018 and visa 18. https://forums.ni.com/t5/LabVIEW/VISA-error-with-TCP-IP-BK-precision-2190E/m-p/3876316 Thanks
  21. I think the biggest mistake from NI was to not add 20 years experienced user into their development team. I believe they only put marketing people and some developer... but no real user. Benoit
  22. Python for me is a script language not a programming language. 😉 Benoit
  23. What about ODBC support? I have a huge project with a superb HAL implemented. I cannot see how I can migrate that to NXG. I feel like having 20 years of my career but on the garbage with NXG. This is not happening with other text language where stuff change, but do not receive a huge refactoring. I guess this is what happens with proprietary language. you use what they offer, not what people really needs. The only good thing for now if the Unicode support. Benoit
  24. Thanks, I'm not a specialist on MIPI. Those information are very useful. Benoit
  25. Zip offers a better portability. In forum, portability prevail over effectiveness of compression. By the way 7zip offer a better one. 😉
