Reading data from USB

hello, i dont sure that i am writing in the correct forum but i will try,
i have web camera connecting to my PC, and i want to record video-clip
by java program command, is it possible?
(is their driver,that i have to download first)

You don't need to shout!
You don't need to open three topics for exactly the same question!
This is still not the correct subforum for asking j2se related questions!
For the ISO/BULK question, you should check the USB documentation. I'm betting that the exception has something to do with it!

Problem while reading data from USB with JSR80

Hi
Iam using Fedora 9 with 32 bit.
Iam using JSR80 api to read the data from USB devices.
I successfully set-up the code as per given on JSR80 site on my eclipsce ide.
below is my code which iam using to read data from usb

Cannot claim an interface on a virtual root hubSo don't do that? I have no idea how to tell, but clearly you need to test a few more attributes before you claim. Or else just log the claim error and continue with the next interface.

Best way to control and read data from multiple instruments?

Hello,
I'm building an application to test power supplies involving multiple pieces of equipment over a couple of different comm busses. The application will also send control instructions to some of the instruments, and read data from some of the instruments. The reading and control profiles will not run on the same schedule (variable length control steps, configurable read interval).
I was thinking of using a queued statemachine (producer/consumer) for the control profile and another to read the data, but I got concerned that there would be collisions between sending control commands and read commands to the same machine. Is there a suggested design pattern for implementing something like this?
Timing of the commands isn't critical down to the milisecond, but I need to collect reasonably accurate timestamps when the data is read. The same is true for the control commands.
Here are the instruments I'm going to use, if the are control, read, or both, and the communication method
Instrument Funtions Comm Method
Power Supply Read data Communicates to PMBus Adapter
PMBus to USB Adapter Read data USB (Non-Visa)
Switch control relays USB (VISA)
Power Dist. Unit read data/control outlets SNMP (Ethernet)
Electronic Load read data/control load GPIB (VISA)
Thermal Chamber read data/control temp Ethernet (VISA)
Thanks,
Simon

Hello, there is a template in LV called "Continuous measurement and Logging".
It can give you some idea how to properly decouple the "GUI Event handler" top loop (where your Event structure is) from the DAQ and other loops.
You do not need to totally replicate the above example, but you can find there nice tricks which can help you at certain points.
The second loop from the top is the "UI message loop". It handles the commands coming from the top loop, and regarding to the local state machine and other possible conditions and states, it can command the other loops below.
During normal run, the different instrument loops just do the data reading, but if you send a control command from the top loop to a certain instrument loop (use a separate Queue for every instrument loops), that loop will Dequeue the control command, execute it, and goes back to data reading mode (in data reading mode the loop Dequeu itself with a "data read" command automatically). In this way the control and data read modes happen in serial not in parallel which you want to avoid (but I think some instrument drivers can even handle parallel access, it will not happen in really parallel...).
In every instrument loop when you read a value, attach a TimeStamp to it, and send this timestamp/value couple to the DataLogging loop via a Queue. You can use a cluster including 3 items: Source(instrument)/timestamp/value. All the instrument loops can use the same "Data logging" Queue. In the Datalogging while loop, after Dequeue-ing, you can Unbundle the cluster and save the timestamp and data-value into the required channel (different channel for every instrument) of a TDMS file.
(Important: NEVER use 2 Event structures in the same top level "main" VI!)

Reading Data from SCXI 1600

Hi Experts,
I am new to this SCXI Interfacing. Kindly help me in the context
I am developing an application which is going to be use SCXI 1125 module and SCXI 1600 controller.In the application I want to allow the user to configure various Task in the front panel.
What are the controls needed in the front panel to allow the user to configure Task
How to read the data from SCXI 1600,
How to differentiate eight channel data coming from SCXI 1125 thro SCXI 1600
Thanks in advance
Solved!
Go to Solution.

True, you cannot simulate the SCXI-1600. This means you will not be able to run your code without the hardware. For simulation purposes you can, however, use another device that would function in a similar manner to the SCXI-1600 in terms of triggering, resolution, and sampling rate.
As for the programming, you would use DAQmx as I had mentioned. There are no examples that are specific to the SCXI-1600, but you don't really need them. The SCXI-1600 is fundamentally a data acquisition module that happens to be in a SCXI form factor with a USB connection. As far as your software is concerned you will use DAQmx to read data from it. So, take a look at the DAQmx examples that gather data from data acquisition devices.
Your task will define how many channels you will be reading. Since you are reading a mixture of measurements (temperature, pressure, and possibly just plain voltages) you will need to decide whether to create separate tasks for each of these measurements that are configured to be specific to that measurement type, or to create one task that simply reads all unscaled channel values (i.e. raw voltages) and then you scale the values in your code. If you open the Example Finder and navigate the tree to Hardware Input and Output -> DAQmx -> Analog Measurements you will see categories for the different measurement types. Many of them have graphs.
If you have not already done so, you may want to start here: http://zone.ni.com/devzone/cda/tut/p/id/3116

Reading data from mlx90129 rfid tag chip by using spi communication with labview?

Hi,
i have evb90129 evalution board in that mlx90129 chip and external memory (cat25128) and three external sensors are there, i am logging data from chip by using rfid reader it ok i am reading. at the same time i configured spi communication and i am trying to read data i am reading data from internal memory not from external memory i tried but i didnt suceed , now can i use labview to read data from mlx chip and external memory. for spi communication i am using sparkfunction atmega168 microcontroller and also i have spi to usb cable? now can i communicate or i required any devies? is it possible?
thanks in advance,
biji.

I suspect the culprit to be the first parameter to your function actually. Calling another function requires the caller to allocate any buffer with a big enough size for the function to write something into. Allocate that array by using Initialize Array with U8 as type and the correct number as size. Pass this size also as read_length. While your code doesn't make use of this I think the third parameter to your function is either wrong or unnecessary.
As you use it now it is really nothing more than a local stack variable which you could declare inside the fucntion just as well. On the other hand what you probably want to do is have a function prototype like:
extern "C" _declspec(dllexport) unsigned char read_Sensor(unsigned *char read_data, unsigned long read_length, unsigned long *byte_transfered);
But you will have to do some modifications in your C code to support that parameter correctly.
That all said, doing the same in LabVIEW using VISA functions would have been done with about two VISA nodes, no DLL headaches and probably already long ago working.

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

Read data from SAP R/3 Class-System

Hello,
first of all sorry when I posted this into the wrong subforum, but I wasn't sure about that. My Question is how to read data from the Classystem I have specified in my ABAP report.
The goal is to read data from my individual class-system as well as data from MM and write them to a table that is to be read by another report. But right now I can't find information about the class system and abap. Maybe you know some tutorials or blogs about right that topic you can suggest?

What class system have you specified in your report?
Normally a class can be used by declaring a variable of type of the class in question, if this class can be instantiated this is. If your class can't be instantiated, but it has only class methods, you can call this method directly.
But there is a lot more to this ABAP Object Oriented Programming, than just this short explanation. Search on SDN for some ABAP OO Tutorials.

Hi, I�m trying to do the same as above, get MP3 from a Shoutcast server.
I got the same fault ("response does not start with HTTP it starts with: ICY") when I tried to open an HttpConnection as bellow:
============================================
HttpConnection conn = (HttpConnection) Connector.open("http://64.236.34.196/stream/1074");
Then I tried to open a socket connection as bellow:
======================================
SocketConnection conn = (SocketConnection) Connector.open("socket://64.236.34.196:80");
String get = "GET /stream/1074 HTTP/1.1";
DataOutputStream os = conn.openDataOutputStream();
os.writeUTF(get);
InputStream is = conn.openInputStream();
But then I got the following error:
=========================
java.lang.SecurityException: Target port denied to untrusted applications
Could someone help me to find out what is going on?
Thanks a lot!

Hi
If you can convert the excel to a csv format, then it can be simply query from DB Creating Oracle External Tables. Best part is that you may still change the CSV using EXCEL.
Following action Points can be adopt;
*1. Convert Excel File to a csv. File Save as CSV*
*2. Create Oracle Directory* ( This has to be the location of your excel file )
SQL> Create directory mydir as 'C:\testdb'; --- "testdb" is the location folder in win for your excel sheet.
*3. Create the External Table*
SQL> create table my_ext_tab (
Field1 Datatype,
Field2 Datatype,
Field3 Datatype,
Field4 Datatype,
Field5 Datatype
Organization external
(type oracle_loader default directory mydir
access parameters (records delimited by newline fields terminated by ',')
location ('my_ext_tab.csv'))
reject limit 100;
*4. Now you can query the table "my_ext_tab"*
Select * from "my_ext_tab";
Please avoid the reformat the data column inside the spreadsheet (CSV).

Without loops how can i read data from associative Array??

Hi all,
I am facing scenario like...
i need to read data from associative array without using loops is it possible,
CREATE OR REPLACE PACKAGE BODY test_pkg IS
    TYPE t1 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
   -- in array we can expect more than one row or sometimes no data also.
FUNCTION test1(vt1 T1 DEFAULT CAST(NULL AS t1)) RETURN NUMBER IS
BEGIN
    -- basically in array we'll get data of column2
    -- this loop should satisfies table1.colum2 = nvl(NULL, table2.colum2 )if array is null.
    -- if array is not null then only compare with array values
    FOR i IN (SELECT t1.colum1,t1.column2
                     FROM table1 t1, table1 t2
                          WHERE t1.colum1 = t2.column1
                            AND t1.colum2 = nvl(vt1, t2.colum2)
      LOOP
        generateTEXT(i.colum1, i.colum2);
     END LOOP;
END test1;
END test_pkg;
in table1 we have date like...
colum1          column2
Jan                  1
Feb                  2
Mar                  3
if i call select test_pkg.test1(1) from dual then output should
be Jan..
and
select test_pkg.test1(null) from dual then it should display all elements from table1.
Jan                  1
Feb                  2
Mar                  3,
Thanks for your quick replay..

i need to read data from associative array without using loops is it possible,
No - you would need to create a SQL type and then use the TABLE operator to unnest the collection.
create or replace TYPE my_nums IS TABLE OF INTEGER;
DECLARE
-- TYPE my_nums IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
v_nums my_nums := my_nums(1, 2, 3);
v_total number;
BEGIN
select sum(column_value) into v_total from table(v_nums);
DBMS_OUTPUT.PUT_LINE
    ('Sum of the numbers is ' || TO_CHAR(v_total));
END;
Sum of the numbers is 6

Read data from a Stored Procedure in Android

I have a Stored Procedure say CustOrdersDetail. I have created a MBO for it in the workspace and deployed it on SAP Mobile Server. I am unable to read data from the stored procedure in code of the Android Application. If I pass a default load argument, then I am able to read data using findAll method. How to get the data from the stored procedure by passing it an argument in the Android Code ?
Message was edited by: Abhijit Kadam

Currently I am trying to call the stored procedure and retrieve the results. The stored procedure accepts 'orderId' as an argument and fetches the Product and Order Details.
