LAVA 1.0 Content

Thanks guys! I saw an example, but didn't realize it was a new feature.

I read your posts on Info-LabVIEW and I can understand your pain. I recall reading this BLOG post by Brian Tyler made in February 2007. I immediately thought "What impact might this have on LabVIEW".

QUOTE(Yen @ Nov 29 2007, 12:26 PM) Yes it is supported but it is not any faster. For fast signals I have used a counter timer module to measure the period. It also sounds like the original questioner, is reading from all of the DI lines and not just one. If this is the case, either change the code to read only the single DI line or use an index array to pull out the channel of interest and then follow Yair advice. Ben

I saw something interesting at the bottom of a LAVA WIKI page. Apparently you can close an array of references in one shot by passing the array (of references) directly to the Close Reference vi. I tried it... but got a conflicting class error. Can anyone shed a bit of light on this? Thanks! RayR

yeah... I'm really looking forward to the usbbeer ! apparently the foam requires more bandwidth

Hi all, I have never really used the capabilities of VI scripting but I'm really considering starting. Let's say I have a VI with a stack sequence with a fistful of steps and some sequence local to pass data from a step to the next, is it possible to turn it to a state machine, programmatically using scripting ? I suspect the answer is yes, which leads me to ask about the level of difficulty I inherited undreds of VIs made a long time ago with stack sequences and I really don't feel like turning them to state machine one after the other. Maybe some scripting geek out there have done something similar or can give advice on how to do proceed. Thanks for any help EDIT : maybe this could ne a feature request for next LV version

QUOTE(TobyD @ Nov 27 2007, 05:35 PM) Well... on european keyboards (at least french, swiss, spanish, italian and maybe more...) there is an alt key and an alt gr key ; just like the shift key gives access to the second "value of non-letter key", the alt gr key gives access to the third "value of non-letter key". Isn't it the same on english keyboard :-o ? EDIT : oops I was a bit slow... Alt gr + E gives € on the french and swiss keyborad, I guess it's the same anywhere in europe, no ?

Congrats Mike, Yet another page in the "Successful Canadian" diary. This is a great site, which I need to visit more often... I like the "independent" aspect of it. No problem with the lava lamps.. you need more of them And best wishes on the road to the 6th dimention!! (or is that dimentia??) RayR

QUOTE(ashishuttarwar @ Nov 26 2007, 12:20 PM) We have used a method similar to what Neville has been discribing in LV 8.2.1. That method should work right up until you want to change the IP address. If you serach through all of the files on the RT node, you will find a couple of files that have the IP address. Just mod those files before writting to the FP and you are off and running. Ben

This sounds like a fun experiment! What hypotheses have you made so far? How do you propose to make your measurements? Do you have any equipment that can communicate with LabVIEW?DMM different lamp types Timers Sensors Can you share anything more with us? In order to solve most technical problems, the scientific method is a wonderful technique :thumbup: .

QUOTE(bono02 @ Nov 21 2007, 01:40 PM) There are two contouring modes: Absolute contouring and relative contouring.... http://digital.ni.com/public.nsf/allkb/062...6256C8C00771B57 Just try on NI.com search for contouring In the contouring modes you write the desired positions into a buffer on the motion controller. Typically you give the motion controller every 10ms a new position. In the absolute contouring mode you write absolute positions: If you write 100, the motor will turn to 100 Inc, if you write 200 the motor will turn to 200 Inc.... When you start a new absolute contouring move, the counter will always start at 0! (Not the same as the Absolute Inc. position...) In the relative countouring mode, you write relative positions to the motion controller. If you write 100, the Motor will turn 100 Inc starting from the actual position. if you write 200, the motor will turn another 200 Inc starting friom the actal position... So if you will move from 0 to 100Inc. at different speeds: Absolute contouring: Write 0, 1, 2, 3, ...... 99, 100,...100 Write 0, 2, 4, 6, .......98, 100,...100 (double speed) Write 0, 0, 1, 1, 2, 2,.... 99, 99, 100,...100 (halve speed and so on) Relative contouring: Write 100 Times a 1, (followed by zeros) Write 50 Times a 2 (double speed) (followed by zeros) Write 100 Times a 0 and 1 (halve speed) (followed by zeros) So with the update rate and the values you write to the buffer you will give the motion controller the desired speed.

QUOTE(Justin Goeres @ Nov 26 2007, 04:43 PM) Use the 'hash' command in an FTP command line session to toggle the display of a '#' for every N bytes transferred. After commanding 'hash', your server should return a message indicating the number of bytes/hash mark. Your server sends the marks, so 'hash' must be implemented at the server. You can also use 'hash on' and 'hash off'. Example of hash marks: http://help.ids.net/ftp/ftpdos.asp I poked around in the LV 8.0 Internet Toolkit VIs and looked at the get file function. I don't see any opportunity to easily extract any progress info :thumbdown: ...

Let me add a comment from a colleague of mine : "ctrl + alt gr + del" also works, so it solves the issue when you only have one hand and a laptop computer Thanks Fanfoue

QUOTE(shahzaib198 @ Nov 26 2007, 03:11 AM) I suggest the following: Try searching this site using the Search button connecting LEDs through Parallel port and giving signal from it If this is homework, you should be careful in hooking up anything to your computer's parallel port; you could damage the parallel interface or even the whole computer unless you know what you are doing. If this is for work or lab use that requires long term use or reliability, you should seriously consider an I/O device that is designed to interface to TTL logic and classic analog signals like this, this or this.

Welcome to LAVA! Glad you joined. Have a look around and don't hesitate to ask questions. RayR

Hey all, my name is Andrea, i'm a bioengineer and i actually work in a neurorehab group. My programming background includes Matlab, Python, some bash and just a bit of Labview. I find labview pretty useful to rapidly develop simple applications, though as a beginner i find it lesser intuitive than othe tools. That's why i'm here: learn, learn, learn.... Thank you for accepting me Andrea Milan, Italy

QUOTE(pbrooks100 @ Jan 10 2006, 09:12 AM) I've always called them Functional Globals. I've read somewhere (might be Ben's post) that FG's are actually a sub-class of Action Engines. Where AE actually have functions within the loop / case structur; thus, when coding, I have my FG folder and my AE folder. The trash folder is also handy
