Onboard programming the 7344...creating data arrays?

I would like to use the onboard programming capability of the 7344.
I have a requirement to set up a data array of X and Y coordinates that would be accessed via an incremental loop.
I guess the array data can be entered into a buffer object, but is there anyway of getting the data from the buffer using a pointer. From what I see the data has to be retrieved from the start of the buffer, or sequentially using the read_buffer function, but on certain conditions I may want to access random sets of coordinates, from within the array, and do not want to ue up all the general purpose variables to do this.

Hi,
The onboard programming of 7344 supports the FIFO architecture.You can run onboard programs from RAM or optionally save them to flash ROM.
The 7344 doesnot support the pointer functions(due to memory size).
The 7344 controllers have 64 KB of RAM and 128 KB of ROM(divided into two 64 KB sectors) for program and object storage.
You can run programs from either RAM or ROM, but you cannot split programs between the two, and you cannot split programs between the two 64 KB ROMsectors.
With an average command size of 10 bytes, a single program can be as large as 6,400 commands.
For example, the 7344 controllers can
simultaneously execute 10 programs, five from RAM and five from ROM,with each program up to 1,280 commands long.
Also R
efer to the Onboard Programming Functions section of the FlexMotion Software Reference Manual for detailed information on all of these onboard programming features.
Please do post any findings that may seem significant to our discussion on the onboard-programming of the 7344.

  • How to change the "content created" date/time in FCPX?

    Since I've had problems importing my whole iMovie event library into FCPX I decided to run some tests with importing individual files (part of iMovie events and originally imported from camera into iMovie). Some of them for some reason got the wrong "content created" date/time in them while in iMovie they have the right date/time set. Does anybody have an idea on how to change the "content created" timestamp?

    I had a bunch of DV files that imported stamped with the file modification date and time.  I did not find a way to change it in FCPX. With FCPX not running, I used A Better Finder Attributes to modify the creation and modification dates of the files in the event folder. FCPX reconnected to them but the event still showed the old range of dates so I created a new event and moved the clips to it. Maybe ther is a beter way but that is how I did it.

  • How do I edit the "Content Created" date?

    I've been storing all of my DSLR video in Aperture 3, and would like to import that video (as referenced Events) into Final Cut Pro X.  So far, I've noticed that some of my video is showing a very inaccurate "Content Created" date; is there any way to edit this and set the correct date?

    I'm looking for the same thing.  I would hope that creation date, and EXIF data could be manually edited inside this "Pro" software, but so far I can't figure out how to do it.  I would like to fix a couple dates that for some reason are off.

  • What is the earliest create date Lightroom recognises?

    I have a file with a create date of 10/20/1984 and windows recognises it as a create date.  When I import it into Lightroom, the create date gets a date of 2007.

    Probably the file was created in 2007 by way of being copied.
    Dates are confusing - e.g. you can have a date modified date that's older than the created date! Why?
    "Date modified" is carried over when files are copied, "date created" is given anew.
    My guess anyway is that these are two different dates, not both the true "Date Created".
    Perhaps you could give screenshots so we can see which exactly dates are being compared.
    Also, consider using ExifTool to assess various dates from metadata within the file.
    But, the answer to your question is: "there is no earliest date" (Lightroom's "internal reference" date is 1-1-2001, but that don't mean much, since dates can be positive or negative with respect to that. i.e. internal dates are just numbers (Midnight 1-1-2001 UTC is a date equal to zero internally) - they get converted to years, months, ..., only when being shown to the user). Granted, all of that is assuming no bugs! - D'ya think there's a bug? One could test by using a file utility that sets the date-created explicitly, then import...

  • Purchase requisition delivery date before the requested/created date

    Dear Experts,
    We are getting an issue that Purchase requisitions created by APO are having Delivery Date one day before of requesed Date.
    Eg Purchase requistion created on 20.02.2015 and having delievery date on 19.02.2015.
    I have checked contract, Purchase info record Tlane all master data settings are ok.
    Planned Delievery Time maintained in the info record is 0 and GRPT time is 1 day.
    Same vendor, contract, PIR exists for 2 material, But we are facing issue only for one material.
    It is an urgent issue , if anyone is having any idea , suggestions please reply to me if any information required will update here.

    Hi Mariano,
    Thanks for your Reply !!
    GRPT and  PDT in ECC maintained as 1 day In material master.
    In Purchase Info record PDT is maintained as 0 days and GRPT is 1.
    I also checked tlane it is coming as 1 day and GRPT is 0 days.
    So which i analysed from some other eg of materials pur req is considering the settings of which is maintained in Tlane, so giving 1 day back date in Pur Req.
    But it solved my previous question but arises one more question that tlane we have not mannually maintained, it always created on the basis of contract in our scenario, so how the PDT=1 day come inside tlane?

    Yes.  It's done through System Preferences>Accounts>Login Options. 

  • Workflows: How to set a workflow variable that is the difference in hours between now and a created date

    I'm trying to create a variable that contains the number of hours between the item created date and Now.  When i use TODAY, it seems to set the time at 12:00 rather than the time now - so that throws the hours off.  Any ideas?
    ajw

    Hi ajw,
    According to your description, my understanding is that you want to calculate the hours between the item created date and now.
    It seems to be not an OOB way to implement your requirement, to get the current time, you need to create a custom workflow activity for SharePoint 2010 workflow. About creating custom workflow activity, you can refer to the links below:
    http://msdn.microsoft.com/en-us/library/hh872790(v=office.14).aspx
    http://blogs-sharepoint-ashutoshmisra.blogspot.in/2013/02/create-custom-workflow-action-for.html
    Or, you can use a third party solution to achieve your requriement.

  • Time for creating big arrays

    Hi,
    My program needed to create several arrays with big size and I found a interesting phenomenon:
    int capacityI=13000000;
    time1=System.currentTimeMillis();
    int[] v1=new int[13000000];
    time2=System.currentTimeMillis();
    int[] v2=new int[13000000];
    long time3=System.currentTimeMillis();
    int[] v3=new int[13000000];
    long time4=System.currentTimeMillis();
    int[] v4=new int[13000000];
    long time5=System.currentTimeMillis();
    int[] v5=new int[13000000];
    long time6=System.currentTimeMillis();
    System.out.println(time2-time1);
    System.out.println(time3-time2);
    System.out.println(time4-time3);
    System.out.println(time5-time4);
    System.out.println(time6-time5);And following is an output of the program:
    15
    16
    16
    5625
    16
    it took much more time to create the fourth array and I could not find the reason. My program is a big program, It did many things before the execution of the above code. Was it related to the garbage collector? I meant the java system ran the garbage collection program before the creation the the fourth array. Was I right?
    I want to prevent this problem, i.e., decrese the time for the creation of arrays. Is there any way?
    Thanks.

    Note that your snippet of test code doe snot require the 5 arrays to be in memory at the same time and is hence not representing your later stated requirement to have them all available.
    Your locally created v1 array is not referenced anymore after creation and therefore eligible for garbage collection, be aware of that. Setting good initial and maximum heap size values as suggested by others is of importance here.

  • Disk Utility 'Disk Image from Folder' looses file create date?

    Hi,
    I have been working on creating backups that maintain the files' create dates. I have found the following anomoly using Disk Utility.
    If I create a Disk Image From Folder, the create dates of all files are changed to be the same as the last modify dates. Not what I want.
    If I creat a Blank Disk Image, and then using Finder to copy the files to the Disk Image, the create dates remain unchanged.
    I can then burn the backup CD's with the Disk Image and the files' create dates are maintained. So, future restore from the backup CD will contain the original files' create dates.
    Does anyone know if Disk Utility's Create Disk Image from Folder is supposed to loose the files' create dates? What other file attributes are being lost? Mac OS X maintains all of these attributes, and create dates via Finder copies, I would expect the Disk Utility Create Disk Image from Folder to do the same.
    Bob Horton

    To follow up on this post, I know at least part of the answer. The difference between the two becomes clearer if you read the documentation (man pages) for hdiutil and asr. Image 1 will be created in file mode, whereas image 2 will be in block mode, ie bypassing the file system. Image 1 will consist of a series of files, whereas image 2 will contain a series of blocks, mirroring the original layout of the hard disk.
    Technically the latter should be faster to restore (in block mode), although Apple recommend the first procedure (see man page for hdiutil). I haven't seen any evidence that images created in block mode can be mounted or restored, although you might be able to burn such images to a optical disks if applicable.
    As I've pointed out in another thread (http://discussions.apple.com/thread.jspa?threadID=1508199&tstart=0) I believe that this functionality should not be offered in disk utility, and I consider it a serious bug.

  • Showing item created date in custom alert template

    Hi,
    I'm working on customizing the sharepoint alert templates for my site collection.
    I got good info on net regading the modifications to be made. But unfortunately, I couldn't fine info about showing the
    Created Date column of the item.
    I need to show the item created data and modiifed date vlaues in my alert email,
    I've 'TimeStamp' property which shows the modiifed date. But Im not getting equivalent property for created date.
    I've tried the below options
    NewValue#Created
    NewValue#ItemCreated
    OldValue#Created
    DisplayName#Created
    None of them are showing hte created date of item.
    There is one attribute 'RawValue' which is giving the created date. but it's display format is really not user friendly
    It shows date as 2013-09-08 T 11,40..Z
    Is there any way to show item created date in alert emails? I dont want to use custom code for it.
    I need to use OOB approach. Or atleast is there a way to format the above date displayed thru 'RawValue' attribute.

    Thanks Arif, it did not work. One note though, if we are using the field name we do not use the brackets:
    <GetVar Name=”OldValue#Created_x0020_Date”
    />
    Both with and without brackets did not
    work. 
    Thanks for the suggestion,

  • How to get the user log from the entried planning data ???

    Dear All,
    Could you help me to give the suggestion regarding that please .. ?? :).
    I have requirement to get the last user who in charge in modifying the planning data.
    Or in the other words, i'm gonna get the log from the entried planning data.
    e.g.
    1. Phase 1 - My Friend:
    Create the planning data :
    Country           Sales
    INA                 $1000
    2. Phase 2 - I update it and create new record.
    Country           Sales
    INA                 $1500          < modified >
    USA                $400           < new >
    Could i get the log from those records ??
    The log can be contain:
    the created user       &   modified user ??
    I just read the article regarding status and tracking system in BPS, but could i cover that requirement ??
    (Because i got that the status and tracking system for creating a workflow for planning).
    Or ..
    Is there other way that can fulfill this requirement  ???
    Really need your guidance all.
    Regards,
    Niel.

    Dear Mayank,
    Tks a lot for your responses.
    I've tried it but in BPS version..
    I saw in the document there is GUID (unique ID), could you explain me what the objective is ???
    I work out to plan to store the user created, date created, and planning level information in the log data.
    What do you think ..
    Is it better to display them in the BEx Report / another manual planning layout ???
    What did you display the log data in your case ??
    Still need your guidance ..
    Really - really thanks.
    Niel.

    Try Below-
    Create variable-
    V_NextDate=If RelativeValue([Request Id];([Request Id];[Ac Create Date];[Act Activity Name];[Act Role Proper Name]);1)=[Request Id] Then ToDate((RelativeValue([Ac Create Date];([Request Id];[Ac Create Date];[Act Activity Name];[Act Role Proper Name]);1));"MM/dd/yyyy")
    In Delays column put below
