How to read multiple Digital samples and plot a chart with time stamps

Hi,
Could anyone send me a code that:
1. Reads 'multiple samples(lets say 4) from single digital input'
2. 'plot digital data as a chart with time stamps'
3. Find frequency
4. Log data into file with time stamps
I have attached the code which i tried.
Thanks,
LK

Plot dynamic data with time stamp

Hi All
I would like to create a plot of dynamic data, (Voltage readings taken with an In 6008) versus time.
When the loop starts taking voltage data I would to plot the data versus elapsed time. Voltage versus time elapsed. I have read many examples and tried for many hours to get this to work.
Please help!
Mike

Hi Mike,
Are you using a Waveform Chart? A chart will continuously plot the data versus time as it is acquired. Try right clicking on the x-axis and selecting Properties>> Display Format. Here you can change the way time is displayed on the x-axis. You can also adjust the way the data is displayed by right clicking and going to Properties>>Appearance>>Update Mode.
I hope that helps! If not, can you indicate what specifically you have set up in your code and how the result is different from the plot you would prefer to create.

Zen Touch: How to edit multiple songs artists and genres at once with new firmwa

With the old firmware I was able to do that with Nomad Explorer. But with the V2 firmware, I cannot use the Nomad Explorer anymore, and Media Source Organizer only alows to edit one track at once. Zen Touch Explorer also does not allow me to do that.
I tried to use Windows Media Player 0 and it worked, but after I closed the program and started it again, all my edits at the Library were gone. If I edit the library and sync to my Zen Touch will it apply what I edited on the library or will it keep the original ID3 tag from the song? How to make the modification permanent to the MP3 ID3 tag on the PC?
I think creative should allow edition of multiple songs with Zen Touch Explorer on the same way Nomad Explorer used to do with firmware V.

I haven't seen a program which does batch editing for MTP devices. Real Player does allow you to edit the ID3 tags of songs on the player, but one at a time.
With most music programs when you change an ID tag on your computer it doesn't update on the player, so you would have to delete it from the player first then retransfer it, or find a program which edits the tags on the player such as Real Player.
The issue is most likely speed, it will take awhile to do batch editing on the player so that could be a reason why programs dont support it..

Read multiple text files and sort them

I am trying to read multiple text files and store the data from the file in vector.
but for days. I am with no luck. anyone can help me out with it? any idea of how to sort them will be appreciated.
Below is part of the code I implemented.
public class packet {

    public packet(int timestamp0,int user_id0, int packet_id0,int packet_seqno0, int packet_size0)
        timestamp = timestamp0;
        user_id=user_id0;
        packet_id=packet_id0;
        packet_seqno=packet_seqno0;
        packet_size=packet_size0;
    public void setTime(int atimestamp)
        this.timestamp=atimestamp;

    public String toString()
        return timestamp+"\t"+user_id+"\t"+packet_id+"\t"+packet_seqno+"\t"+packet_size+"\t";
}Here is the data from part of the text files. ( the first column is timestamp, second is userid, third is packetid.....)

How to output the digital clock and synchronization signal from the NI USB-6211

Hello,
I need to connect the NI USB-6211 to control a digital to analog convertor chip (AD5541). However, this chip requires three input signals :1) Clock input, 2) Logic input or a synchronization signal and 3) Signal Serial Data input (CS, SCLK, DIN).
how to output the digital clock and the synchronization signal from the NI USB-6211?

Hi SaberSaber,
You should be able to use the counters to generate a pulse train that could be used for clock and synch purposes.
Hope this helps. Let us know if you have more questions.

How to read in a file and change the column attributes

Hi,
I'm new to java and i'm stuggling to find a way to read in a text file and perform calculations on the data, such as to normalise it.
What in want to do is normalise the data by finding the greatest value in a column and then divide all the other values in the column with that value.
I know how to read a file in and store each line in a vector but for this problem i think i need to store each column in an array, but i'm not sure how to do this.
Can anyone help please?
Thanks

Hi,

the other values in the column with that value.

each column in an array, but i'm not sure how to do

ThanksI think this should work but I wrote it out without completely thinking about it (hopefully to get things started).
So if you had this:
age height earnings
0 2 100
1 3 50
2 1 0
For the age column you'd take 2 as the largest and then divide 0 and 1 by two to get 0, .5.
First build up test files that seperate the columns in different ways. With spaces, tabs, and the ASCI Control character for null ( I think it's 0 ). Your program should detect
numbers and spaces, tabs control character, commas and periods (for money). Because numbers don't have spaces it should be easy to keep track of which column
you're in.
Store each line into a 3D String array with each index containing a String built up from the chars scanned in on each line, when a blank area is found followed by another
number iterate the column index. When you come to the end of the line set column == 0 and row+1.
private String[][][] test = new String[2][6][1];
20     3      11      14      44       0
4      5       7      80      91      49
test[0][0][0] would be row 1 col 1 value 1 ((20))
test[0][1][0] would be r1, c2, v1 ((3))
test[1][0][0] would be r2, c1, v1 ((4))
test[1][2][0] would be r2, c3, v1 ((7))
test[1][5][0] would be r2, c6, v1 ((49))

i uderstand , thanx...
i managed to open an audio file and placed it in the sampler,i can play t sample in the little keyboard in the zones section, howver i dont know how to play it with my controller... the sample shows in C1 on logic's keyboard but if i play C1 on my controller nothing happens... how can i fix this?
Also, i noticed the sample plays from beginning to end once i click on it, how do i do to just make it last until i release the key? like a logic sound??? (in case i want to play a small portion of the sample only)

How can I use the "Copy and paste" tool in order get stamps in the same position in different pages (Acrobat XI for PC)?

With Acrobat 6.0 I was able to copy a stamp in the same position (I mean "exactly" the same one) of different pages just by using the "copy/past" tool.
Now I am using Acrobat XI and it seems like it is not possible anymore: I am copying a stamp and I am trying to past it in anoter page, but it appears in the center of the page (or wherever it wants to...).
Does anyone have a solution?
Thanks in advance.

Thank you very much. I'll be waiting for you message.

How to open a pdf file and then attach it with images

I am new to Indesign Server.
I'm currently working on a pdf.
I have a white blank pdf template.
that I want to attach/glue it with images.
How to open a pdf file and then attach it with images.
Please, help me.
Thanks.

First step would be to make yourself familiar with InDesign desktop version.
Whatever you intend to achieve, do it there manually. (see regular app docs or forums)
Then try to automate your steps with scripting (see scripting docs or forum)
If you can do it with a script in the desktop version, that script will likely also run in ID Server. (see server forum).
If you can specify missing features not achievable thru scripting or manual use, reconsider to write a plugin (this forum).
A seasoned C++ programmer will need a few months to learn the basics, wade thru tons of documentation etc. Alternatively consider to hire a consultant to do the development work for you.
