Without NI DAQ device- how to get data from MSP into labVIEW and process it

Hi,
I do not have an NI DAQ device. I have an MSP430 and my sensor is an ADXL335 Accelerometer. How do I get data from my MSP into labVIEW and process it?
Just looking for a nudge in the right direction. I'm having a hard time finding resources on labVIEW that don't involve NI specific DAQs.
Thanks in advance,
Aziz

There are many ways to get data into LabVIEW that do not involve NI-DAQ devices.
I think your easiest option would be to stream it via serial port if the data rate isn't too fast.

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

How would I create an USB Barcode Scanner Listener using Adobe AIR?

I want to create a USB barcode scanner listener that would read in the scanned barcode, and place the barcode in a field in my AIR App even if the program wasn't focused on that particular field in the App. If the client was using the application at the time for something else the scan would be buffered in AIR till requested or the AIR App has been idle for x period of time where upon the field would be brought into focus.
How would I go about this (I'm developing on windows) Was hoping for a USB solution within AIR but not fussy at all if I have to go outside AIR to solve this problem. Java, Flex, ActionScript, Flash, C, C++, C#, VB (currently I've developed the rest of the App using Adobe AIR and JavaScript)
I thought after some research that I could make a Java App (if all else fails) that listens and buffers the input and passes it along using a socket but JUSB doesn't work on Windows properly.
I'm not stuck on any one particular implementation or idea just want to get development underway so... Any ideas? or suggestions would be awesome. I've googled a lot but haven't found any examples or solid suggestions, so any URL pointing to that information would be great too, if you know of a good one, then I'd be able to read up on any suggestion.
Thanks,
Marty

Thanks Joe,
Just for anyone else. I bought a Metologic Scanner - VoyagerCG. I was trying to get it to work using Java USB for a bit with no luck. But if you get this scanner or one like it, it can be configured as a Virtual COM Port. Which is very very easy in Java to set up as a listener and use sockets to transfer the data and listen within AIR.
This PDF has links to drivers and instructions if this is useful to anyone.

How to get data from subsites list of SharePoint 2010 in ssrs

Hi,
Can someone help me on this issue.
I want to create a report using ssrs, I have some of the data in SQL and some of the data in sharepoint list.
First I need to go to SQL and get the data from the table which contains URL for the subsite in sharepoint.
after that I need to go to all the subsites and go to perticulat list in the subsites and get data from that list.
for example, their is a top level site "abc"
it contains sub site "123", "456","567", etc.. All this sub sites contain a list by name "Sample List", Now I need to go to that sub site list(Sample List) and get list-item column say "created By" which
is created on particular date.
in my report, I need to print the sub site "url/Title" which comes from SQL database and list-item column "Created By" of that sub site list "Sample List".
I tried using subreport inside a report by using "Microsoft SharePoint List" as a datasource, but when it comes to real time we don't know how many subsites will be created, so we can't create a datasource for each subsite site.
I guess we need to be using XML as a datasource, but how can we go to particular subsite in query while using XML, since all subsites have list with the same name ?
I appreciate your help.
Thank you,
Kishore

Hi Kishore,
SQL Server Reporting Services(SSRS) supports expression-based connection strings. This will help us to achieve the goal you mentioned in this case:
Create a new report
Create a Data Source in the report with the connection string like this:
http://server/_vti_bin/lists.asmx (We use static connection string instead of expression-based connection string now, as it is not supported to get fields based on expression-based connection string in design time. We will change it to be expression-based
connection string later)
Create the data set(as you have done using XML query language). Please use list name instead of GUID in the listName parameter.
Design the report(e.g. Add controls to the report)
Now, let's change the connection string to be expression-based. First, please add a parameter to the report, move this parameter to top. This parameter is used to store the sub site name.
Open the Data Source editor, set the connection string to be: ="http://server/" & Parameters!parameterCreatedInStep5.value & "_vti_bin/lists.asmx"
In the main report, pass the sub site name to the report we created above via the parameter created in step5
That is all.
Anyway, this is actually a SQL Server Reporting Service(SSRS) question. You can get better support on this question from:
http://social.technet.microsoft.com/Forums/en/sqlreportingservices/threads
For more information about Expression-Based connection string, please see:

If there is anything unclear, please feel free to ask.

How to get data from Oracle using Native SQL in SAP.. Problem with date

Hi Masters.
I'm trying to get data from an Oracle DB. I was able to connect to Oracle using tcode DBCO. The connetion works fine
I wrote this code and it works fine without the statement of where date > '01-09-2010'
But i need that statement on the select. I read a lot about this issue, but no answer.
My code is (this code is in SAP ECC 6.0)
DATA: BEGIN OF datos OCCURS 0,
      id_numeric(10),
      component_name(40),
      comuna(10),
      record_id(10),
      status,
      sampled_date(10),
      END OF datos.
DATA: c TYPE cursor.
EXEC SQL.
connect to 'LIM' as 'MYDB'
ENDEXEC.
EXEC SQL.
SET CONNECTION 'MYDB'
ENDEXEC.
EXEC SQL PERFORMING loop_output.
SELECT ID_NUMERIC, COMPONENT_NAME, COMUNA, RECORD_ID, STATUS, SAMPLED_DATE
into :datos from lims.SAMP_TEST_RESULT
where     date > '01-09-2010'
ENDEXEC.
EXEC SQL.
disconnect 'MYDB'
ENDEXEC.
How can i get the data from that date?? If i delete the where statemet, the program works well, it takes 30 mins and show all the data, I just need the data from that date.
Any help
Regards

Please refer the example in this link which deals with Oracle date format.
You can finnd a command DECODE which is used for date formats. If you have a look at whole theory then you will get an idea.
