Where is the PID (FPGA) Express VI?

I have LabVIEW 2013 RT and LabVIEW FPGA installed on my Windows 7 machine. Which palette is the PID (FPGA) Express VI on? I have looked on both the RT and the FPGA palettes. I have looked for the example C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\control\PID\fpga llb\CompactRIO. The example is not on my machine.

I don't have an FPGA Math & Analysis -> Control on 2012 or 2013. Maybe I failed to load everything I need. Here is my palette.

Configuring the PID (FPGA) Express VI

Hello,
I'm implementing a control system using the PID (FPGA) Express VI. I was wondering if crucial to provide the correct sampling time: Does the Express VI's functionality depend on it, or is it only for calculating the initial quantized gains?

Hi there, The sampling time directly affects the integral and the derivative gain (see the formula at the details section over here). Unless you are doing a proportional control (only) I don't see a problem. For more reference check this other link.

Where is the build table express vi located in the function table?

I must be blind but I can't locate the build table express vi in lv8 or 8.5. Someone slap be upside the head and point it out. Thanks

It's on the Controls palette. Were you looking on the Functions palette?

HT4262 where is the apple airport express ID located?

just bought an apple airport express. can anyone tell me where the airport ID can be found?

Unfortunately, Apple no longer prints the Ethernet ID and AirPort IDs on the AirPort Express.
You can locate the IDs by configuring the Express to connect to your network, and then use AirPort Utility to display the information that you need.
You did not provide information on the type of operating system that you are using on your computer, so we cannot provide any more specific information about locating the IDs if you need more help.
If yu are using a Mac, and do not know what version of the operating system you are using, you can find that information by clicking on the Apple icon in the upper left corner of the screen, then clicking About This Mac. The OS X Version Number will be displayed. Post back with that info.

How do I specify if the PID object is direct or reverse acting?

I have a process that requires a reverse acting controller - eg if the PV is above the setpoint, I need to increase the controller output to lower the PV. Where in the PID object configuration do I specify this?

Pat,
I think - you can achieve a "reverse acting" PID controller by setting the Gain value negative. However, if you manipulate the PID parameters you should know what effect it will have on your system. If you want to be sure you should simulate the parameter before you apply them to the "real" world. In addition you could verify the -Gain setting with the formula (position/velocity control equations) given in the Lookout online help of the PID control object.
Hope this helps

PS: I always keep in mind what my control profssor told us once - "just a minus sign (sign change) in contol theory could mean a lot"

PID (FPGA) - Convert 16bit output to 24 bit

Hello,
Im controlling a device in Closed Loop using the PID (FPGA) vi. The output of this is I16, but it would be nice if I could convert it to a I24, or I32. The output of this vi is sent to two different Analog Outs on my Op-Amp circuitry. The op-amps are set up as summing amps, so it would be ideal to send the lower 8 bits to the first AO (fine output), and the top 16 (15+sign) to the second AO (coarse output).
I haven't found an easy way to do this yet. So far, I've been thinking of just using the I16 output value, split it into two 8 bit numbers. The lower 8 bit controls my first AO. The upper 8 bits is combined with another 8 bit register that gets incremented everytime the 8-bit number becomes saturated, and controls the 2nd AO.
I've attached a pic to make it more clear (I hope?). If I should be doing this another way, please let me know.
Or maybe I need to be controlling this system with 2 parrallel PIDs? One controlling the coarse control, the other the fine. The feedback would be the same for both PIDs.

Hi bones,
even on FPGA you should be able to use "split numbers" and "join numbers" functions...
And you can use boolean operators on numbers. Like sign = I16 && 0x8000
That way you would get away from all those number TO boolean array TO cluster of booleans TO unbundle TO bundle TO boolean array TO number conversions (also called RubeGoldberg, search for this in the forum!).

Where is the serial key on the pack of Labview 7 Express??

Where is the serial key on the pack of Labview 7 Express??

Hi
It can be found on a card within the box , there are usually two stickers (Self adhesive) to be attatched to the CD Pack or filed away for reference. It is not printed on the pack itself.

FinalCut Express - where is the serial number ?

I had to change motherboard on my macbook pro (not hard disk), and then final cut express ask again for serial number - I have the original box and cd, and cant find this number !
==> where is the serial number ?

There should be 2 peel-off stickers attached to the documentation.
Very distinctive as the print at the top is red and the numbers below are black.

The trouble with 'expression' -- how to edit that

I just walked to the corner bodega ( even though its korean sooo bodega is misleading ).. to get some beer...
ITS BEER THIRTY -- yipee !
and on way back down the block where I live ( which is suburban ) some boy kid on a bike was riding and playing with a girl kid ( probably was his slightly older sister - these kids probably around 12 years old ) in front of a rental property with some spanish americans hanging out in their cemented yard on hammocks near bar b q...with their own kids...(they have planted another hopeful "veg garden" around the perimeter of their so called yard...tomato plants etc )...so anyway, the picture here is a "neighborhood" of sorts with a somewhat lower middle class family atmosphere in a fairly lower class area on the verge of becoming middle class ( with God's help ).
And anyway, I passed by the boy kid on the bike and smiled at him cause he seemed to be a decent kid having fun with his friend ( they were sorta laughing about something and having fun before I showed up as the big "adult" and looked at me ). His smile back was like sunshine and true and he immediately recognized he could keep having fun with his friend and I wasn't a "threat" , but instead some sorta "neighbor". She did the same more or less ( I think she had some devious design re: the game they were playing ... like " OK, you think you're so great on that bike, try to CHASE me ! " or something like that....kid stuff... and fun thank God. This neighborhood has it's share of bad things going on in the streets at times. And that leads to my focus on " The trouble with expression".
A lot of people, like me for example, can't express themselves well in some ways. I didn't say , " Hi there kids ! What's new ? " when I met them on the way back from the bodega. I didn't stop and ask what the heck they were laughing about. Nor did I speak to the spanish people adjacent to the kids ...in their "yard" ...with the bar b q and hammock and obvious friday afternoon socializing they were into....
We in nyc area are typically a mixed bag of races... I'm white, kids were african amer ( black but more like brownish if you ask me ), spanish people like mexicans IMO... who cares. This is suburbia so you can imagine how more mixed it is in the city.
Anyway, the reason I don't express myself so well in situations like that ( spontaneously on the street ) is cause I used to stutter real bad as a kid.. couldnt talk... so I clamed up. All my life I've been fighting that disability ( and other "challenges" re: learning, reading , writing, asthma , etc ) in terms of the "repercusions". Kids like me make fun of me cause I stutter...I can't fight back verbally and lash out physically... become a "maniac". Get kicked out of city schools etc... Trouble maker. Can't express myself, fight back with words....when kids are mean to me. After a while they dont matter much as if they are mean I just keep quiet and keep mouth shut and start "thinking" instead... how to keep on top of this person and not let things get crazy... meet the challenge.
Turns out I'm not stupid and at some point my being " quiet" becomes a positive thing.. peers start asking my advice.. I'm suddenly a " deep thinker" in their eyes. I go from being disabled ( stupid ) to being " a deep thinker" about the age of puberty... when nobody knows what they are doing anymore.
I start thinking about expressing myself some other way than talking.. like maybe draw pictures... paint stuff, do things to have fun with people that doesnt put me in the " limelight".. where I have to talk etc. More success follows this tendency to socialize and express myself... and I discover that chics like the strong silent type.
( I have been into gymnastics thru my fathers infactuation with it since age 2 -- which I think eventually ( inadvertantly ) " cured me " of many of my learning disabilities etc -- (talk to an OT about this and modern child development stuff to know what I mean here )
Meanwhile I am very fond of dogs as my family has dogs one after the other and I am one of their best friends. I find I can communicate with dogs better than I can communicate with people sometimes. This seems to be a problem in some cases with some people, but for me it never got crazy... where I " loved dogs " more than I " love people ". I have never loved any dog more than any person and shudder when I think of those who do. Those people who do have more problems than I ever had to deal with.
And now, after all these years ( I am now 60 ), working on movies and tv stuff etc as a crew person with some college fine art schooling ( eventual photo major ) to get me started, I got into this " editing " stuff... A program I can actually " use " on my mousey computer introduces me to a more " final product " than I ever had access to before.
BUT I don't shoot motion pic stuff, cant afford that - and never could before basically, and now I think about the triple threats and future of movies and tv as a business... as well as the tools ( in this case the editing programs in conjunction with the cameras ( arri, panavision etc ) ) and the desire to express something ...
This has to be ( if you want an audience ) ... " tell a story ". You could just put a camera on a rocket ( strap it to the rocket ) and shoot the takeoff etc and show that.. but you need a V.O. saying " well, I just shot off a rocket and this is what it looked like"...to bring the experience to the audience... or else IMO there is no story.
Which leads to what's going on now in the world of reality tv, episodic tv , some big movies, etc. Telling a story is more than showing you stuff that you just wouldnt have seen if you hadn't been there yourself. Telling a story is more like saying something that bridges the gap between your own experience of life and its challenges ( of being part of your neighborhood and making sense of your own childhood and being an adult now maybe ).. and what others also have gone through to get to the same conclusions....
This is the object of " expression" IMO, whether you can talk about it, draw pictures about it, or make music about it...
And the editing program is a tool to help do that.. it is not the end all or purpose of life or the " personal crusade" in the long run.
It's one reason scary snakes often shock people out of their desire for comfort and predictable living... makes you think about that one serpent in the garden of eden you create for yourself .... and IMO who cares what editing program you use to write that and shoot it ??

Steve Grisetti, the MOD of the Premiere Elements forum and co-founder of a video/photo/editing Web site, Muvipix, did a nice article, "Don't just make a movie - tell a story." His audience was more consumer video editors, than the folk that we see around here, but his points were well-made, and were embraced by many in the Muvipix community.
I think that too many, forget that concept - and I am talking Hollywood and NYC here. It's almost as if, when the story breaks down, they instinctively know to throw in a car chase, or big explosion.
I know that I cite it too often around The Lounge, but that was what I enjoyed most about the LOR trilogy. It told a story. Now, though I had some exposure to the story, when much younger, I have to admit that I never read Tolkien, though almost everyone, that I knew, was busy with every book. Still, I only knew some of the high points, and not much more. However, almost immediately, I was drawn into the story, and only wished that I did not have to wait so long between episodes. The FX were cool, and I am a technoid sort, but it was the story that hooked me. I had read several articles on the FX production, so WAS looking for some of that, but what I wanted was the story. This is one that I will buy the BD "Director's Cut" of, and do a marathon. I have seen each segment, maybe three times, but never back to back to back. I still need to fill in a few blanks, and an entire day of viewing should do that - no phone, no visitors, nothing but LOR.
As far as human communications, I can talk, even more than I write here, but only concerning things that I care about. I am horrible at "small talk," and would rather addrss an auditorium of 10,000, on something that matters to me, than talk about the weather to a single person at a fund raiser. Not that long ago, I was seated next to a potential donor at a charity dinner. I was rather dreading it, and when she mentioned that she did not drink (what, no wine?), I was worried. At some point, early in the evening, the subject turned to politics. Now, I usually am very quiet on my feelings, as they are not exaclty politically correct, and worry about hurting feelings, or making a scene. I fielded a question on Senatorial candidates, and just decided to answer from my heart. Her eyes lit up, and I did not notice that the event had ended. Her husband was standing, as was my wife, and we were talking politics, talk-radio, FoxNews, Senator John Kyl, Will Rogers and much more. I found that we were kindred spirits. Finally, our spouses pulled us apart, and we departed. We continued that conversation at 2 - 3 more events during "the season." One day, my wife informed me that she had just given $10M to the foundation - the largest single gift ever. At least she wasn't a screaming liberal, as I would surely have really messed up the deal... However, had it all been small talk, I would have found a reason to excuse myself and hide in the bar for a few hours.
Also, the way that our society has developed, I will smile, nod, and say "hello" to strangers on the street, but always leave it at that. I am sure that many walk past and think "he wasn't all that friendly." They are probably right, but at least I was pleasant to them and did not rob them! Heck, I will usually tell telemarketers, "No, but thank you for your generous offer on that time-share... "

Where is the user trace file?

I have issued the statement below to enable sql trace in session 260 ,and it execute successfully.but i can not find where the trace file in directory $ORACLE_BASE/admin/testcs/udump (testcs is my database name).
SQL> execute dbms_system.set_sql_trace_in_session(260,34880,true);
PL/SQL procedure successfully completed.
where is the trace file?
By the way,how can i find the information about the package DBMS_SYSTEM which is not in ORACLE references?

Did you issue some queries after turning tracing on? The trace file might not be created until there is some activity in the session.
I know that DBMS_SYSTEM is documented in the O'Reilly Press book "Oracle Built-in Packages" by Feuerstein, Dye & Beresniewicz.
However for tracing I think that Oracle expects you to use the dbms_support package:
execute sys.dbms_support.start_trace_in_session -
(sid => &sid, serial => &serial, waits => true, binds => true)Or for Oracle 7.3.4 or 8.0 you can use oradebug. Example:
select pid, spid, username from v$process;
PID SPID USERNAME
8 25807 oracle
SVRMGR> oradebug setorapid 8
-- or -
SVRMGR> oradebug setospid 25807
-- turn on
SVRMGR> oradebug event 10046 trace name context forever, level 12
-- turn off
SVRMGR> oradebug event 10046 trace name context off

Where is the database object administration GUI in Oracle XE 11g?

Please read my whole question, because I'm sure people will misunderstand, and tell me to load http://localhost:8080/apex in my browser. I know that is there.
I am a previous user of Oracle XE 10g, but I just installed Oracle Express 11g. I only want to use it to get a local instance of Oracle database. The 10g APEX UI provided an easy way to administer database objects (users, schemas, and the like), but it appears the 11g APEX UI is some kind of weird application development environment that I don't want to use. It doesn't even seem aware of the schemas I created in the database using SQL Plus.
So, where is the regular admin GUI for Oracle database objects like users/schemas (i.e. something that will list the schemas that exist in the database, and allow me to add or delete them)? Or does 11g force you to do that using SQL (in which case, I'm going to go back to 10g).
Thanks,
Jeff

No, SQL workshop is not what I want.
Basically, I don't want to deal with this concept of a "workspace" at all. It's useless to me and just gets in my way. All I want is a a UI where I can view a list of the schemas that exist in the database, and manipulate them easily.
I have TOAD, so I could use that, but I liked the old 10g administration GUI, since it provided the exact functionality at the exact level of complexity that I needed.

Where is the Just added link in iTunes 10.7

Updated to iTunes 10.7, where is the Just Added link hiddden, It was there last week.

The "recent releases" is all that seems to be available now. Whether the old "just added" section will ever reappear, no one here can say. You can express your desire for that section via Apple's feedback page, if you wish:
http://www.apple.com/feedback/itunesapp.html
It's been removed before and then reinstated, so it's possible they'll bring it back.

I often wish when I select a word to right click and choose dictionary to to find out the meaning of the word. Currently I have to copy, go to a dictionary web page, paste and search. And I spent a lot of time for that. I'm not that technically oriented to suggest how this can be achieved but just as an idea, may be Mozilla can partner with dictionary web sites by making a plug ins or include a dictionary with Firefox itself

I am sure there are Extensions that do this.

How do I get the PID of a child process in java using JNI?

I am writing an app in Java (for **nix) that will spawn multiple processes (using Process objects). I want to be able to get the PID for a particular child process (not the parent). How can I do this?

You could try an extreme hack of using JNI to read whatever field of the java.lang.Process-derived class may hold a native process id. This would be unsupportable beyond the exact JVM(s) you can test it on, and should only be a last resort, but within these constraints it may work well. The source code for package java.lang gives clues of where to start hacking.
