• analog input on USB-6009 - what potentiometer to use for this test?

  Hello, I am referring to this video

  http://www.YouTube.com/watch?v=rSNRG_Ddl1s

  What is the resistance (ohm) the potentiometer used in the film?

  Thank you

  Luke

  They know the author of video ...

  Since it is connected to the output of 5V to the DAQ card, you don't want to use too low of a low value.

  A pot more of 500 ohm must work safely. Exact value is not critical for this demonstration. Rear wiper terminal must be connected to the analog input, the other two legs go 5Vout and GND.

• Frequency measurement of analog input using DAQmx C APIs on SMU-6341 map

  Hello

  I use Linux DAQmx and attempt to measure the frequency of analog input using the map DAQ SMU-6341.

  There is an ANSI-C frequency measurement example:

  / usr/local/natinst/nidaqmx/examples/ansi_c/Analog_In/Measure_Frequency/Cont_Freq-Int_Clk-SCXI1126

  However, the call to DAQmxCreateAIFreqVoltageChan results in the following error:

  DAQmx error: selected physical channel does not support the type of measure required by the virtual channel you create.

  Create a channel to a type of measure that is supported by the physical channel, or select a physical channel that supports the type of measure.
  Property: DAQmx_AI_MeasType
  Required value: DAQmx_Val_Freq_Voltage
  Possible values: DAQmx_Val_Current, DAQmx_Val_Resistance, DAQmx_Val_Strain_Gage, DAQmx_Val_Temp_BuiltInSensor, DAQmx_Val_Temp_RTD, DAQmx_Val_Temp_Thrmstr, DAQmx_Val_Temp_TC, DAQmx_Val_Voltage, DAQmx_Val_Voltage_CustomWithExcitation

  Task name: _unnamedTask<0>

  State code:-200431

  DAQmx does support the function of the frequency on the map 6341, or should we use examples of voltage and calculate the frequency manually?

  Frequency of HAVE it is a type of channel that has been supported only on the SCXI module name of the example.

  You will need to use a voltage input channel and calculate the frequency manually for your device.

• Code generated by executing itself (for example can have the JIT compiler?)

  BONE of the Playbook, like Apple's iOS, prevents an application from self-production of his own code to execute?

  For example, I can't launch V8 javascript engine of Google on Apple iOS because the operating system will not allow the application to have a page of memory that is executable and accessible writing. (in order to avoid the trojan style dodgy apps)

  So, I just wanted to know if there are similar protections on the playbook, before wasting too much time!

  Finally, I'd like to port V8 for the playbook - the possibility of including the code Javascript in a native app is very useful!

  Well, I solved my image-memory - the call of the function when you try to call strlen with inside of foo()...

  The compiler generated instructions relative branch (short) for my call to strlen.

  There are several ways to work around this problem:

  1. use - 25mdelongueur-calls during the compilation, even though it may turn on long calls unnecessarily elsewhere, when all I really wanted was long calls inside my function foo().

  2. use #pragma long_call / #pragma long_call_off or __attribute__ ((long_call)) on the functions that you want to generate a long advertisement.  You must also __attribute__ ((weak)), if you declare the function in the same file as it is called for.  for example:

  __attribute__((long_call,weak)) int bar(const char *str) {         return strlen(str); }
  
   int foo(char *str) {
      return bar(str);  // this will generate a long-call to bar() which wraps strlen() for me. }
  

  * Note that the call to strlen in bar() will not be a long call, but given that the wrapper bar() is not running of the bunch, it's okay.

  3. load the address appeal explicit function within the function foo():

  int foo(char *str) {
      size_t (*strlenptr)(const char*) = &strlen;
      return strlenptr(str);
  }
  

  See you soon,.

• Examples of code for the robot LDAP plugin is missing

  I downloaded and installed ITS 10.1.8 version but the sample code for the robot LDAP plugin isn't the case to find. The "sample" directory is missing. The example of code removed for any reason or is it replaced by something else? We must be able to search an LDAP compatible to v3 for our new dashboard application.
  
  The document "Secure Connector Software Development Kit" for ITS Version 10.1.6 says the following:
  -Oracle shipped three sample plug-ins that supports analysis, analysis of database table and analysis file LDAP directory.
  -ORACLE SECURE ENTERPRISE SEARCH comes with three sample plug-ins sub $OH/search/sample/agent.

  Yes, samples of tracks were removed in 10.1.8 because they have not been sufficiently tested, or considered good enough to ship.

  However, I have the LDAP robot and I'll be happy to send it to you (STRICTLY no guarantee, of course!) If you leave me an email for roger dot ford at oracle dot com.

• 6225 DAQmx names for measurements of the differential pair

  All,

  I came across this post trying to find out if there was documentation to show who's analog inputs are coupled together and what name DAQmx controls call these pairs.

  http://forums.NI.com/T5/Multifunction-DAQ/device-pinout-for-the-PCI-6225-in-differential-AI-mode/m-p...

  Messages from the author a drawing which I think is correct, but it is not an official document of OR.  I'm looking for documents that says exactly what the name is for each pair during their use in a command DAQmx.  I know literature 6225 AI0 and AI8 form a pair, and AI1 and AI9 are a pair, etc. etc.   What I was trying to find, is documentation that shows that the name of each of these pairs, what I should do in the DAQmx calls during a differential measure.  Currently, I am assuming that the AI0/AI8 pair is referred to as AI0 when the measure differential.  I have just followed the list of pairs in the manual of the user from left to right and from top to bottom and naming of AI0 to AI39.  I really was hoping that there was an official document that says what were the names of each differential pair.

  Can you point me to the appropriate document or tell me that it is not an and that my assumptions are correct?

  Thank you!

  Doug

  Doug,

  There is not an official document similar to the one in the related post that shows the AI0 + and AI0-. The differential channel will always be referred to by the positive terminal. It doesn't matter what differential channel number it is. For example, the Channel 9 differential uses AI16 as the positive terminal. All configurations in DAQmx must be configured using AI16 in differential mode. The drawing was published is not official, but it is correct.

  Kind regards

• example of code source (fmb)

  I'm new in the development of the oracle. I need examples of code for the oracle 10g Forms Builder.
  
  I notice that it is the thing that is not yet in the knowledge of Google.
  
  I wonder who the oracle forms source code is not available on the web. whereas if we're talking other tools such as .net or php! thousands of examples of code are available for almost all kinds of requirements to do a job.
  
  I'll be very grateful if someone could give some code examples (fmb, rdf, etc.)
  
  Thank you

  Don't know how this is different from any other language (at least as far as I know), but: learn the basics, try to resolve your issue with the knowledge that you have and if you get stuck there is no shame in asking questions (for example here), of course, explaining your problem in detail and not the it does not work please give me the code , it's urgent! type of question...

  and for what it's worth, even if it is not directly related to the forms: asktom, the developer of the Application Guide and PL/SQL reference manual are great references to learn stuff.

• CSC analog inputs, for example, ai07 or ai13 modules

  On the CSC-I like the I-07 series, what is the relationship between the inputs of channel physical (ai0 ai1) as seen in measurement and information Explorer (MAX) compared to the 1-2 and 3-4 module PIN numbers? Pins 1-2 are the same as ai0 and pin 3-4 identical ai1 or is it the opposite? CSC Quick Start Guide, or the User Guide for the series AI CSC CSC Configuration Guide have this information. Thanks for any help!

  Hi Louise,.

  Page 6 of the User Guide and specifications shows a block diagram.

  http://www.NI.com/PDF/manuals/371066d.PDF

  On the right side of this diagram, you can see that the E/M material inputs DAQ series is AI (X) or As (X + 8).  Since these modules are modules of conditioning, signals, they do not in reality a measure, they simply affect the signal so that you can take a measurement by the DAQ hardware.

  I (X) will be the channel that you specify on the DAQ hardware (for example, entry zero analog channel).  If you perform a differential measurement, spacing must be eight apart, and HAVE (X + 8) will be the other side of the signal that connects to your DAQ hardware (in this example, the channel analog input 0 + 8 = 8).

  Please let me know if it helps.
