  1. excellent tips tomi. I agree with gary, but i use TrackMan® Wheel http://www.logitech.com/index.cfm/products...,CONTENTID=5002 In reality windows is what made the mouse big. Autocad is a great example of how a software developer can integrate command line into cad software. Learn coding shortcuts similar to those found in vi and vim. By learning keyboard shortcuts you really decrease the use of the mouse and improve your overall productivity - especially for a programmer like myself.
  2. from post: http://forums.lavag.org/index.php?showtopic=6776 QUOTE(chrisdavis) Thanks for clarifing the intentions of programmer/non-programmer for each product. Is this really the main difference? I was hoping the SignalExpress would similate sequential logic and show the waveforms. Maybe log waveforms comming in from several digital/analog lines [protocol analysis].
  3. chrisdavis, Thanks for sharing some of your insights. I still need some things clarified. Note: i'm moving some of the relavent information into my other post. QUOTE(chrisdavis) Would it require the EXACT daq hardware? Example in lab i may have an expensive bnc daq board but in production i may be able to use screw type terminal blocks. QUOTE(chrisdavis) Is this "team's" solution viable for the mass market, I would say that it depends the market, and what it is willing to bear. I've seen presentations featuring Labview's ability to run a DARPA unmanned vehicle race, provide feedback from oil well's in remote locations, and power a LEGO robot to react like a scorpion. Sound like interesting projects. I just didn't think a daq board as a customer deliverable, but i guess it can be. I guess I just approach the problem differently, most freescale microcontrollers have adc on them. I can see the development to deliverables shortening by using ni tools. So here is my current belief, --[do you agree?] For every item sold: 1) it will be more expensive 2) the packaging is larger 3) its brought to market the fastest This is good to know, most of my work has been in small embedded projects. If i ever get a commercial account with a large budget and needs something developed asap, Ni with visual studio.net might be the best choice. Beats having to wire it all yourself with surface mount components. QUOTE(chrisdavis) Your USB to UART / serial port bridge could be accessed using an API known as VISA. thanks for the tip, I'll take a look at it. QUOTE(chrisdavis) NI has a good instrumentation newsletter that has new ones each issue. another great tip, thanks.
  4. well if labview supports oop you should be able to inherit the built in xml writer and override the render event which takes a string builder.. talking more of how its done in .net if your using measurement studio you should be able to create an xmldocument object which has properties to createElement, xmldoc->save(filestreamobject); -lm
  5. if your not planning on using visio I recommend: http://argouml.tigris.org/ bsd license + my favorite license type!! I've used it to create object diagrams: inheritance, aggregation, composition, interafaces, abstracts sequence diagrams to describe when when objects are created and how they interact in respect to time. state diagrams ... although visio creates nicer ones here. use cases - for powerpoints presentations in reality a uml package should be able to generate code. I've used argo for that sometimes. must mostly use it for planning/designing. code generation might be better in visio but sometimes setting all the properties .. consume to much time and you don't put enough time in brainstorming. I don't like visio just cuz it looks ugly and license .. although i have it free like all my other software.
  6. Hello, I'm new to labview deployment. I'm working on my senior project and noticed a team implementing their project completely with labview. They plan on deploying their labview application to the client once complete. I assume the user needs to install a client similar to java's virtual machine. So their customer can run the application. Is this correct? So does this mean the customer needs to buy the same daq equipment used by the development team? won't that be expensive? How much extra cost is this adding? I always pictured labview as a test/development platform and never a production line item. The only place I can see this beneficial is in a large control system where it will greatly reduce the # of custom controls that need to be created in c# or qt. But most control systems i've seen are developed inhouse and not sold to a mass market. So is their solution viable for mass production? From my experience I've used serial or com port to interface hardware with a pc. My senior project interfaces hardware with usb using a usb to uart bridge and c#. (my project is a transmission controller designed for gear heads that want to fully control shiftpoint of an automatic transmission. They use my gui to load/save user preferences and flash them to the controller.) In my application controls don't even exist for what i need. Example i created a graph where the user can drag the lines on the y axis to modify default operation. I'm guessing this is where Measurement Studio for Visual Studio .NET seems to fit in. I can create my custom controls and use labview's dll for data aquisitions - that would normally be received through serial/com/usb . Anyone with any thoughts?

  7. Hello, I've used labview at school since 2004/05 but i've always used the daq boards provided by my university. http://sine.ni.com/nips/cds/view/p/lang/en/nid/1173 - Terminial Blocks: BNC Terminal Blocks and Shielded Screw Terminal Blocks I'll graduate in may so i need a similar system to continue my projects @ home. [want more functionality though.] Also advice on software because labview might not be the best for some of the tasks i need to accomplish. There is so many products for both hardware and software I want some advice before I spend $ at http://www.ni.com/products/ price range < $1500. Software Applications: I need labview to be able to function as a function generator and oscilloscope. (all boards should do this but just incase) I would like a logger, example to examine the usb protocol, I would like to see the actual waveforms on the line. In the past I've used a "chart" and outputed the data to a file, however I'm ready for something more sophisticated. NI LabVIEW SignalExpress ????? http://zone.ni.com/devzone/cda/tut/p/id/2805 - picture of waveforms i would like to be able to see. http://sine.ni.com/nips/cds/view/p/lang/en/nid/202480 - another I'm currently using a usb to uart bridge but would like to be able to implement this in raw form. In the past for my sequential logic circuits i've used max plus 2 with an Altera EPM7128S PLD. https://www.altera.com/support/software/dow...dnl-student.jsp Since the time i created my intial circuits the company created Quartus II to replace maxplus. I rather consolidate my software rather than have 3 different programs for my circuits: labview, quartus, and orcad Does ni provide something to help me design sequential circuits? What do ya use for sequential circuits? I've searched on google and I only found vi's for flip flops http://www.ee.surrey.ac.uk/Projects/Labvie...Flops/index.htm Say i build a sequential circuit using that guys vi how do i get the simulated waveforms. Also can it peform validation for me instead of examining the wave form myself. Example: give the values of present state, my new input, and what the expected output should be And the software tell me if it passed or failed for that condition. Maybe setup a regression tests to test all the possible combinations.[meaning give it my state table and it pass or fail and tell me which conditions failed.] Is the software and hardware sold seperately or is it one package? Example can i use a terminal block and be able to use LabVIEW SignalExpress and Measurement Studio for Visual Studio .NET ? http://sine.ni.com/nips/cds/view/p/lang/en/nid/14040 http://sine.ni.com/nips/cds/view/p/lang/en/nid/203094 seems like only the more expensive boards are advertised with those software. Hardware Applications: Maybe a board that functions with openg.org, however that is not a requirement just a want. DIO requirements I'll be mostly programming freescale controllers and testing DACs; so digital I/O >= 8 would be beneficial. AIO requirements I'll mostly be testing clipping circuits, triggers, filters, .... and testing ADC on the controller so >= 2 Analog I/O Reason for greater than is so i don't have to take apart my circuit to test another one, especially for Screw Terminal Blocks. thanks for any advice on software/hardware and general workbench setup I might need.
