sinewave timed using triggered

I'm new to labview and the research I've done on call loops etc. produced a lot of information that I could not understand. Everything I want to do is generate a while a sinusoid which would be the last 1 second every time I press a trigger button loop (and then the amplitude would go to 0). I only know how to generate a sinusoidal signal all the time... Could someone please help? I did not understand how use periods if loops is the way to do it. Thanks for the pointers or the examples.

Good afternoon my8os,.

You don't need a timed loop.  The easiest way to program, it's to have a configuration of the task of data acquisition with the waveform appropriate.  Start the output and a timer on the trigger of the user.  When the hour is up, stop the loop/task.  You can use the Express VI elapsed from 1 second.  It will display a Boolean value when the time is up.

If you want to have a somewhat more elegant (and complex) program, you can use a Structure of the event for user input and enter your loop output of 1 sec when necessary.

  • Performance using triggers

    Hi all

    In our project my team is working on the coding of PERL.
    So all the ins/upd/del DB from one table to a another table we write all the code in PERL only

    As when the table is inserted/del/upd with a record of same data must be replicated to another table for future reference. This coding, everything is done in PERL only...

    I suggested using TRIGGERS in the Oracle to do the same thing

    So please suggest me which option would be useful in this case

    Thank you

    Hello

    There are many solutions, triggers is an option but may be slow. You can take a look at "multi-table insert", then the coding can be done in PERL, something like:

    INSERT ALL
    INTO s (s_id, s_name) -- one table
        VALUES (id, name)
    INTO s_sub (s_sub_id, s_id, s_sub_name) -- the other table
        VALUES(id2, id, name )
    SELECT s_seq.NEXTVAL AS id,
        s_sub_seq.NEXTVAL AS id2,
        object_name AS name
    FROM all_objects;
    

    I think that this will be the simplest solution.

    Other possibilities are the options of replication of the oracle database, or the same watercourse (maybe Change Data Capture). Search for these terms and you will find some examples.

    If the solutions depends on the resource and knowledge.

  • Solution for the mutation of table of error when using triggers

    Hello

    Could you please give the solution for the error table mutation during the use of triggers. I'll give you the simple scenario here,

    I created a trigger on the employees table, whenever all DML operations takes place in the employees table, it must run the trigger body. I intentionally used also of the employees in the body of the trigger table. Please give me the solution.

    Triggering factor:

    create or replace trigger test_trigger

    before you insert or update or delete employees

    for each line

    declare

    an employees.first_name%type;

    Start

    Select first_name from people where job_id = "AD_PRES";

    end;

    DML statement:

    Update employees set salary = 20000 where job_id = "AD_PRES" (I run this query)

    Error message:

    ORA-04091: table HR. Is the transfer of EMPLOYEES, the function of triggering/can not see

    ORA-06512: at "HR. TEST_TRIGGER', line 4

    ORA-04088: error during execution of trigger ' HR. TEST_TRIGGER'

    Can anyone tell, in what other scenarios, we get this error or recursive table mutation?

    Thanks in advance

    Hello

    When you create a trigger on a table, you cannot edit/query this table the trigger is not completed.

    You can use

    (1) transaction of Pragma autonomous

    (2) instead of row-level trigger, you have statement-level trigger

    (3) to 11 g, try with COMPOSITE trigger

    Try below to avoid it (a solution):

    create or replace trigger test_trigger

    before you insert or update or delete employees

    for each line

    declare

    PRAGMA AUTONOMOUS_TRANSACTION;

    an employees.first_name%type;

    Start

    Select first_name from people where job_id = "AD_PRES";

    COMMIT;

    end;

  • What is someone is able to pause a video using triggers to pause/stop on the timeline?

    I Don t average of spam the Board due to a problem I can´t solve, but is there anyone out there that handles the following:

    1. import a video on Board (just let´s say it s long of 20 seconds for this example).
    2 reading of the video from the beginning by a 'play' button.
    3. making the video stops automatically at different intervals by the pause/stop setting triggers in the chronology of the scene.
    4 playing do the video blog posted in break / collapsed by clicking the play button.
    (Example: when clicking on the video would play to the 5 second mark and then stop because of a trigger stop/pause 5 seconds mark.) To keep on playing the position of stop/pause 5 seconds you´d have to click play again)

    If even, what triggers the timeline that you use to stop/pause the video?

    You´d be my hero if you could help me with that. I ve been tried for three days straight now.

    OK, I managed to get this working. That's what I had to do, for anyone who might know rape the same mind...:

    1. turn the video into a symbol.
    2. on stage, symbol and video not autoplay.

    3. set play in video playback at the beginning of the video.
    4. set the break in the video playback at the time preferred on chronology of symbol.
    5 expand as much as you can about the chronology of symbol and set trigger 'stop all' for the symbol right after the break reading of the marking.

    6. setting game in video playback just after the "stop all trigger" marking.
    7. create the button with the symbol of action game.

    Now, you can play a video that stop a pre game break and make countinue to run recliquant on the play button.

    For me, nothing else has worked. The buttons pause and stop video features didn t do something when you don't do what I did above to the letter, even when used in that I found a very logical way. Adobe should address these things if they want on board to be a common tool for everyone to use. I know I'm new to this, but if I upload a correct video, read it in the timeline and just insert a basic video pause or stop all off and nothing happens, well then the basics are neglected. I shouldn´t have to go through trial and error ALL the time.

  • How to track the changes on the table, not not using triggers

    Hello
    I would like to track DML changes on the tables. As I have several tables, it is not effective to write triggers.

    Is there any installation that I can do at the database level.

    I use 11g R2.


    Thank you
    thanks fran,
    
    I am a developer DBA with no access to db as sysdba.
    
    how can I access au$ table
    
    SQL> show parameter audit_trail
    
    NAME TYPE VALUE
    -----------
    audit_trail string DB
    SQL> audit select,insert on ctrl_batch;

    *
    ERROR at line 1:
    ORA-00942: table or view does not exist
    

    Hmm... a contradiction in terms...

    (1) audit trail must be in "DB, EXTENDED" see sqltext in the table sys.aud$.

    (2) If you have not logged: $sqlplus / as sysdba, if logged in SQL > conn / as sysdba (and of course sqlplus sys / conn sys as sysdba / as sysdba).

    (3) in your example, you are using views of dictironary of data that require dba (such as system or sys) privileges, but the owner of aud$ is sys. So, probably you use user system, right? Try to connect as sys as I told you in step 2 and try again.

  • Management key id primary auto increment without using triggers

    Hi, we have a lot of table in our database with the installation of key ID primary autoincrement than they are in MySQL since we are in the process of migrating to Oracle of MySQL. Now in oracle I learned recently that this application requires the creation of a sequence and a trigger on the id for each table in the type field. We have tables of 30-40 in our scheme and we want to avoid the use of database triggers in our product, as the management of database is out of reach for our device software.
    What are my options to implement the auto increment id feature in oracle... aside from manually specifying the id in the code and it management in the code that would change many existing insert statements. Some info about our application environment: groovy grails, hibernate, oracle, support for mysql

    It is NOT auto-increment, you can avoid manual entry. When executing the INSERT statement, you must use the value of the sequence.

    Change your cursor for select payroll_id, time_period_id, period_num and remove the "updates". If none of those are the primary key, select the primary key as well. Then set a variable to periods_to_go (payroll_id, time_period_id, period_num), then update the table set nom_de_variable = attribute20 where primary_key = cursor_name.primary_key.

  • Cannot acquire with cDAQ in hardware mode timed using DIAdem DAC

    Hi all

    I use DIAdem DAC to acquire the cDAQ + 9225 + 9219. 9219 acquires the use of single point mode that works very well. However, I tried to acquire waveforms 50 kHz 9225 with the file attached dac. However, I found a problem on the block of the clock, as shown below.

    How could I solve this problem and gain the waveform with 9225 using DIAdem DAC?

    Sincerely, Kate

    Hello Kate,

    You must connect the NIDAQ-In1 exit the Save block block. In addition, you must change the parameters of the horloge1 block. The material is always measured in mode "DAC-kernel". "The software clock" is used for frequencies of up to 10 kHz clock (depending on the material and the PC). If you want to measure more quickly, you can use the "Clock" mode

  • Support for triggers in PCI-6602 for counter input / output meter opearions


    I'm sorry, it took a lot of time to test my application in a real NI PCI-6602 map. I am now convinced that put off against channels support start trigger, arms and relaxing break start trigger. But the input meter channels use pause trigger and trigger start of arms only.

    I designed the app so that counter 0 is used as a channel of the meter and meter 1 serves as an output of the meter channel. The two channels are configured to use triggers to start of arms. Arms start triggers should come from a line of the RTSI. Using the terminal line 0 RTSI route connect API to arm the trigger for the start of the two channels. So when a pulse comes to line 0 in the RTSI two counter starts counting.

    One last thing, I'd like to know, is how RTSI signals are generated? I know that RTSI is used for synchronization of several cards of NOR.

    If there is only Board can we use the signal of the RTSI?

    Can the hardware PCI 6602 itself generates all signals to the RTSI lines?

    Thanks in advance.

  • Canon T1i and Speedlite 580EX off camera use for

    I have a T1i and 580EX (not 580EX II) flash. I would like to use the flash on the camera. Would need other devices (trigger, transmitter)? If not, then could you give me the guide the way in which it is defined. Thanks in advance.

    The 580EX can works as a Canon E - TTL wireless (optical line-of-sight) master or slave flash.  You can use a commander of on-camera flash or get another able to work as a master or slave flash.  A few hot flashes like the 430EX II cannot function as a 'slave' (non-master).  The 580's can be.

    The bult - in flash on a T1i will not trigger a slave Canon E - TTL remote.  I think the T3i was the first of the rebel line to achieve this functionality.

    You can use triggers to 3rd party... optical or radio.  Some of them are extremely cheap, but do not have E - TTL.  The end part 3 higher units that manage the E - TTL are quite expensive (Skirball mentioned the brand of POCKETWIZARD (English) which has a very good reputation... but is not cheap.  )

    POCKETWIZARD (English) has a problem of reliability with Canon 580EX II units (do not know if it would have the same problem with a 580EX II).  The real problem is that when you do E - TTL, there's a pre-Flash and certain communications made before the actual shooting takes place (it's very fast-), but when the preflash fires, the 580EX II was generating enough RF interference that the PocketWizards could not communicate reliably and the flash would not be triggered as expected.  There were a few attempts to create RFI shielding and I even heard of services that change the guts of the flash to reduce the interference (which would, of course, canceled warranty.)

    How can I stop and start the process using triggers in Disqualification?  While planning a job, I can not able to see the folder of trigger / trigger name in the tool palette? What kind of file should be placed in the Triggers folder. If you know someone, let me know. If someone has shared an example script which is very useful for me.

    Thanks in advance.

    Malila Chandra.

    It is a common use case.

    You create a job that has a closed Web Services trigger configured before executing the first phase (right click on the stage in the Task Manager, select Configure, you will then see this screen below), with the work or or jobs you need to added stop. This must be configured to be 'blocking', i.e. the rest of the work expected on the triggering comprehensive action.

    Work should have a phase which refreshes the data staging, and another phase (or a phase of post trigger) that returns your work in normal real time (using the trigger on the job).

  • In a widget of Composition can triggers dynamically reposition in what concerns the different sizes of image of hero?

    I'm working on a design where using Composition widget is best suited to my needs for customization. My plan is to position the trigger under the goal of hero image thumbnail. As each trigger is selected, a different hero image appears as it should. However, each of my hero images vary in vertical height. If I post the triggers, say, 50px below #1 and #2 image image is much larger, #2 image overlaps the triggers. Not good.

    Is it possible in this widget for do triggers dynamically reposition (force push) depending on the size of image of hero, now a uniform fill between?

    Or is this only possible by giving each project it's own, renouncing a widget in total and by treating the thumbnails just as page links?

    (Visuals provided here):

    Thanks for any advice you can share,
