  1. To make it clear Here is what I mean of stopping the DAQmx stimulated device. I do from step A - E; and step E is what I mean stopping the DAQmx stimulated device. 3. Use the NI-DAQmx Task in VI Logger Lite to complete a data logging application. a. Open VI Logger Lite. If you do not have VI Logger Lite, download it or request a free CD. b. Right-click My System>>VI Logger Tasks and select Create New. c. Select Using NI-DAQmx and click Finish. d. Select the NI-DAQmx task for the NI-DAQmx simulated device. Leave all settings in the defaults, and click Run task in the toolbar. Figure 9. VI Logger Lite data logging task. The data logging task begins. Data from the NI-DAQmx simulated device is displayed in the Real Time Data viewer. e. Click Stop task.
  2. I read this article "NI-DAQmx Simulated Devices" ( ). And I am trying the example code " Cont Acq&Graph Voltage-Int Clk VI ", follow exactly what the webpage say. However, I don't understand Don't understand how to use stimulated device; and the point of having Logger. Why I can keep reading data by using the example code in all the following setting????? I stop the NI-DAQmx simulated device (without closing the program, still have DAQmx task) after generate a sine wave (one hundred points). There is 1 VI Logger task. I run the example code. The example code can continuously read data. I stop the NI-DAQmx simulated device (without closing the program, still have DAQmx task) after generate a sine wave (one hundred points). There is no VI Logger task. I run the example code. The example code can continuously read data. I stop the NI-DAQmx simulated device and (close the program, still have DAQmx task) after generate a sine wave (one hundred points). There is no VI Logger task. I run the example code. The example code can continuously read data. I stop the NI-DAQmx simulated device and (close the program, DO NOT have any DAQmx task) after generate a sine wave (one hundred points). There is no VI Logger task. I run the example code. The example code can continuously read data.
  3. QUOTE (faisaldin @ Feb 23 2009, 03:42 PM) I did similar thing a year ago. I wrote a program to track the path of moving cursor on an empty plot. I use property node to find out the cursor X and Y coordinate.
  4. QUOTE (sky @ Feb 23 2009, 10:59 PM) You can get the idea by reading "parallel port read and write loop" example in your LabVIEW
  5. Hi, I am rewriting a program. An AI single scan (read the oldest data mode) is needed to translate to DAQmx, but I have no clue how to set the DAQmx read to do the same thing. Does AI single scan equal to read the whole buffer? Or does it equal to read 1 sample?
  6. QUOTE (ASTDan @ Feb 23 2009, 02:13 AM) thanks This is a very good information.
  7. I write up a data acquisition for my friend, but I don't have the corresponding hardware to test. Any program that can mimic the hardware for me to test my program? Thanks
  8. QUOTE (jgcode @ Feb 21 2009, 02:20 PM) very good information thanks
  9. Dear all, I need to rewrite a program which use the traditional DAQ vi. I could not find those VI in my LabVIEW 8.5, but I need to understand the meaning of those VI to rewrite the program using DAQmx. Here are my questions In A, what is the meaning of AO config with AO and AO1 input? Should I use two separate DAQmx Create Channel VI to replace "A" ? Ignore B In C, what DAQmx VI should use to replace singal update VI? In D, what DAQmx VI should use to replace AI S-scan VI? In E, I don't understand why Trigger config is connected with the AO write (output related). Does the Trigger config VI control the AO write??
  10. Thanks! :thumbup: I forget I can use this function
  11. Dear all, I am converting my Matlab code into LabVIEW block diagram because my current computer does not have Matlab. I have a few lines of matlab code to find the 1st element which is larger zero in an array, but I have no idea how to convert it into LabVIEW block diagram. I used flag and if-else in Matlab, so "" if (flag is not ON and array>0)"" can give me the result. I was trying to use the case structure to replace the if-else structure in the Matlab code, but the case structure has to connect to output for both true and false conditions. Any suggestion? btw, can you see my personal photo under my name zmarcoz on the left column? if not, what should I set to display my picture?
  12. QUOTE (vultac @ Feb 8 2009, 07:01 PM) You can use "enable indexing" in the for loop to store the output of each element into an array, then you can display the whole array later.
  13. QUOTE (zmarcoz @ Feb 7 2009, 09:02 AM) My question may be too stupid :thumbdown: because I find gmail.vi from NI.com after a few hours of googling I am not sure whether the VI will work correctly because it required the .net framework which I am downloading http://digital.ni.com/public.nsf/allkb/484...625749E006512EE
  14. QUOTE (tilli @ Feb 6 2009, 12:21 PM) If I do that, I will use time stamp to create the file names and STORE the update file names in a txt file. That means total 4 files, the name of 3 of them will keep changing and the updated name can be found in the "STORENAME.txt" (fixed name) file. I hope I understand your question correctly.
  15. Dear all, Does anyone know any LabVIEW related job opening? Please tell me only the NON security clearance jobs. I am a fresh graduate international student in US, so I cannot get any security clearance jobs thanks :worship:
  16. QUOTE (Ton @ Feb 4 2009, 10:30 AM) Thanks! I learn something new
  17. Dear all, I find out there is smtp email function in LabVIEW. I googled the "LabVIEW email SSL"; and get some information said the VI not support SSL . Does anyone have any suggestion how to make a program with those VI to work under SSL condition?
  18. QUOTE (jcarmody @ Feb 6 2009, 07:08 PM) I see! thanks! I misunderstood what system label was. I thought system label was using edit text function to put text on the block diagram. Now I understand that there is a system label function to label the wires. thanks again
  19. QUOTE (jcarmody @ Jan 19 2009, 09:39 PM) Could you please teach me how to label the wires? I cannot find this function in LabVIEW; and I always do the system label only. Thanks

    My CLD plan

    QUOTE (zmarcoz @ Jan 21 2009, 04:36 PM) JAVA is too difficult; and I cannot finish reading all material by today. And I need to reschedule the SCJP exam to Feb25. By the way, thanks so much for people who read my resume. I lose one interview because I can't work until Apr1. However, I should have an interview for a LabVIEW programmer job at the end of the month. Thanks for everyone :worship:
  21. Will someone go to the Developer Education Day 2009 at D.C. too???? BTW, Happy Chinese New Year
  22. Dear all, I read a few sources of control parallel port because I have a question of controlling signal bit in parallel port. One of them use "out port vi", but what is the register address to go to the VI and how I can find out the address. The other one suggests to use VISA, I used VISA to control serial port. However, I have no clue how to use VISA to control a signal bit in parallel port.
  23. QUOTE (Louis Manfredi @ Jan 22 2009, 02:30 PM) As a non native speaker, I really don't know how long will it take for a native speaker to read 2 pages The staff in the career department spent no more than 15 secs to read my resume Since I read so many times, I could not find out any other problem myself (I am weak to find the "s" problems) I thought they were professional and could read my resume in very high speed; I also thought my proof reading was good enough. Therefore, my resume has so many mistakes Thanks so much for reading my resume
  24. QUOTE (jdunham @ Jan 21 2009, 08:39 PM) Very good guideline, thanks Thanks for everyone I could not get any help when I was in school. Even if the staff in career department read my resume, she did not point out any problem. By summing up all suggestions, I modified my resume. Now it is 20% shorter, and straighter to the point Feel free to give me more suggestions :worship: <== the first time I see this icon, and it is very suitable to use it here
  25. Originally, I wanted to do the exam with 2 months. I change my mind after many people give me advice My plan is a week or two after May5, 2009. Why?? Haha Because I will get 200 dollars voucher on LabVIEW developer day will be on May5 at D.C. (I am living in MD, and I have already registered for it.) (.............I have a question, I registered online, but I still have not get official response/reply from NI. When I will get their official acceptance??) A friend of mine gave me the intermediate I and II manuals. Yes, manuals only, not included any practice excises. Do anyone want to sell his/her intermediate I course kit? I also borrow "The LabVIEW style book" by Peter Blume; and plan to read it after fisinh the course manual Any suggestion? Any way that increase my chance to pass CLD?
