Comm of ARMS with SPI

• Narrow ARM of SPI VI reference works do not for me LabVIEW 2009.

  I use LabVIEW 2009 Embedded for ARM in collaboration with the Council of development of LM3S8962 and the MCP3008 10 - bit ADC chip. I'm trying to use the base screws of SPI to communicate with the MCP3008 - see the attached excerpt from VI to my current attempt. I can initialize the SPI reference, read two bytes of data from the ADC, but when I try to close the reference, the application crashes. If I am the narrow ARM of SPI reference VI in a diagram to disable, the program terminates normally, and I get to see my two bytes of data printed on the OLED. Any ideas?

  Thanks in advance,

• The best way to commit to InDesign with InCopy

  Hello Mr./Mrs.

  I have a few questions about the collaboration between InDesign with InCopy. My question is which how best to commit to InDesign with InCopy, number one or number two?

  1. I usually make an assignment of all in InDesign, and I put this file (.inca) on a server. If the editor can open the inca of the server file. Instead of the editor, I take the .incx file or server resources.
  2. The Publisher to open directly the server Indd file, so I'm not necessary to create the assignment file.

  
  I hope someone can help solve my problem. Thank you for attention.

  Note: what server and the requirement of network for better result InDesign and InCopy workflow?

  Best regards

  I respectfully disagree; I think that the assignments are for most (not all) more trouble than they are worth.  For your local work, continue w/INDD files only. It just makes it simpler.

  When an editor wants to work on something out of the site, the designer can do an assignment on the fly for them.  It might even be the entire document as a great task. Because the stories are already exported, simply make the assignment (create new assignment in the assignments Panel menu) and drag and drop stories related to this assignment. Other people can still open the INDD file, but they will not be able to edit the stories that have been packaged for the remote Publisher.

• The research of a column with comma separated values with ora-text

  I use the Oracle 11 g 2 XE and Oracle Text to a web search engine.
  
  I've now created and text indexed a CLOB keywords column that contains words separated by spaces. This allowed me to expand the search, as Oracle Text returns the rows that have one or more keywords that are stored in this column. The contents of the column are visible to the user and serves to 'expand' the search. This does not work as expected.
  
  But now I need support several words or even sentences. With the current configuration, Oracle Text will only search for each keyword. How should I store the phrases and configure Oracle text so that it will search entire sentences (exact match is better, but the partial match is fine too)?
  
  Example of content column of two lines (values separated semicolon):
  "Hello, Hello; y at - it anyone out there? Nope; »
  "the just; basic facts; »
  I found a similar question: looking for a column with values separated by commas, except that I need a solution for Oracle 11 g with it's freetext search.
  
  Possible solutions:
  1st solution: I thought to redraw the DB as follows. I would like to make a new array of keywords (pkID NUMBER, nonUniqueID NUMBER, singlePhrase VARCHAR2 (100 BYTE)). And I want to change the column previous keyword to KeywordNonUniqueID, holding the ID (instead of a list of values). At the time of the research I had INNER JOIN with the new keyword table. The problem with this solution is that I will get several lines containing the same data except for the sentence. I guess this will destroy the ranking?
  
  2nd solution: is it possible to store sentences as an XML in the column key of origin and somehow say Oracle text to search for in the XML?
  
  3rd solution: separate individual phrases with spaces, but replace the spaces in sentences with the underscore or something (making a single word). If a phrase "why Hello there, Johnny!" is saved as "Why_hello_there, _Johnny!
  
  4th solution?:
  
  Note that, generally, there is a lot of sentences (less than 100), nor that they will be long (one sentence will be up to 5 words).
  
  Also note that I am currently using CONTAINS, and needs some of its operators, to my full-text searches.

  When you talk about "phrase", do you mean "a list of words separated by a comma other sentences?

  Isn't that the definition of "sentence" used by Oracle Text, where it simply means "a list of words in the order defined."

  If I understand your requirement, you want to have data such as:

  "aa bb cc dd".
  "aa ee dd ff.

  and give priority to the first on the second if someone looking for "dd".

  First, to conduct research in the comma separated list, you should look for in a section. You can either explicitly define sections of field such as
  AA bb cc dd
  Or you can use the PHRASE special section and set the sentence delimiters correctly. This is done with the attribute BASIC_LEXER punctuation

  Then you have the number you want to find only words where they are the only words in the section. That's the same problem, I address in the last post of this forum entry:
  Contains: match exactly

  Our solution will be substantially the same, some surrounding text with special markers, and then prioritize a phrase search with these special markers each side of the word.
  We need to do a treatment some additional, although, as we need to surround each "sentence" (in your terminology) with special markers. I did it by surrounding the text with "XX1"... Condition2"then by replacing every comma with"Condition2, XX1"as part of a MULTI_COLUMN_DATASTORE:

  drop table names;
  create table names (id number primary key, text varchar2(50));
  
  insert into names values( 1, 'just and kind, kind and loving' );
  insert into names values( 2, 'just, kind' );
  
  exec ctx_ddl.drop_preference  ( 'mylex' )
  exec ctx_ddl.create_preference( 'mylex', 'BASIC_LEXER' )
  exec ctx_ddl.set_attribute    ( 'mylex', 'PUNCTUATIONS', ',' )
  
  exec ctx_ddl.drop_preference  ( 'mcds' )
  exec ctx_ddl.create_preference( 'mcds',  'MULTI_COLUMN_DATASTORE' )
  exec ctx_ddl.set_attribute    ( 'mcds', 'COLUMNS', '''XX1 ''||replace(text, '','',''XX2, XX1'')||'' XX2''' )
  
  exec ctx_ddl.drop_preference  ( 'mywl' )
  exec ctx_ddl.create_preference( 'mywl', 'BASIC_WORDLIST' )
  exec ctx_ddl.set_attribute    ( 'mywl', 'SUBSTRING_INDEX', 'YES' )
  
  create index namesindex on names(text)
  indextype is ctxsys.context
  parameters( 'datastore mcds wordlist mywl' )
  /
  
  select score(1),id,text from names where contains( text, '
  
    
      
         XX1 kind XX2 
         kind
      
    
  
  ', 1) > 0
  order by score(1) desc
  /
  

  Output of this is:

    SCORE(1)        ID TEXT
  ---------- ---------- --------------------------------------------------
       52         2 just, kind
        2         1 just and kind, kind and loving
  

• Remove the comma from parting with something else in a file download

  I have a file which gets downloaded and then read and inserted into the database. The problem is when I read below records that should be of 3 indices, it breaks the index with the file delimited by commas in 5 index.

• Why SPI participates with clock select on 5761/2 scanners?

  The CLIP reference for the 5761 5762 sample clock commit signal States, and "when going from FALSE to TRUE, updates the sample clock according to the settings defined by the signal of selection sample clock."  Shipping examples bookends the rising edge of clock sample commit with SPI Idle check.  Why the SPI is involved with setting the sample clock?

  Thank you

  Steve K

  I have a requirement to PLL to IOModSyncClock, so if SPI become inactive within the time limit, should I give up?  In other words, if SPI will not idle 10 ms after the rising edge of clock sample commit, so I am not locked (for example clock select = IOModSyncClock lock).

  I would not abort, rather I'd throw a significant error that allows to recover gracefully or stop the execution. Otherwise, it seems that you have the correct impression on which should involve the remaining false SPI Idle. However, I think 10ms sounds a bit too short. I'd go with at least 100ms, probably closer to 1 s just to be sure. If it takes more than 1 s, then you can assume that something has not been configured correctly before you start setting the clock.

• SPI Communication with PIC24HJ256GP210

  Hello

  I need make the SPI Communication with hardware PIC24HJ256GP210 in LabVIEW 2010 with NI USB 8451.I want to send 8 bytes data and receive data of 8 bytes of PIC. I'll send data byte-by-byte change the signal of the chip Select (CS). Before you send the data I will send ENQ (mark 3A) to check the status PIC, then after receiving ACK (Acknowledge as A1), I will send the data packet.

  My test procedure indicated below,

  • Setting clock polarity at zero (LOW idle), a second Edge clock Phase) and the clock frequency of 1 MHz to device NI USB-8451
  
  
  • 3 sending data (ENQ) and followed meaningless data byte by byte, also change state Chip Select
  
  
  • No explicit deadline has provided since the sending of the API takes 20msec to run
  
  
  • Receive the acknowledgment of receipt (A1) of the sensor
  
  
  • Send DataPacket [Eg: A5, 03, 02, 00, 00, A6, 2 c, DD] byte by byte, also changing chip select signal
  
  
  • No explicit delay gave between each byte from API takes 20msec to perform sending
  
  
  • Send 8 bytes , which means less data byte-by-byte, and receive byte-by-byte data PEAK
  
  
  • Received all of the data of 8 bytes with an incorrect value

  If please review my test procedure and give your comments if you have worked with SPI or if you have any input for my query.

  Thanks in advance.

  Note: Tie my code with this mail for your reference.

  Kind regards

  Nicolas.

  Hello O_Proulx,

  Thanks for your reply.

  Communication SPI after sending the data we send again meaningless bytes, which equals how many bytes we would like to receive the answer System.So we cannot read the data in the same VI as you mentioned in the code.

  My problem has been resolved. Byte meaningless, I need to send the file HEX .beacuse 'AB' has been developed in this way.

• Experience with the acquisition of digital workflow series of ADC on SPI or Microwire

  Dear Forum,

  I would like to acquire a digital stream via a connection series of two sons of an analog-digital chip such as AD7679. The device says it is compatible with SPI and Microwire to achieve protocols.

  There are screws for the manipulation of these protocols series? And can I use a card in the series M as the PXI-6289 for this?

  Thank you!

  Hi cwierzynski,

  Thanks for your post!  For your application, I highly recommend the USB-8451, designed to connect with SPI hardware.  You can program your application in LabVIEW using NOR-845 x driver, which installs several examples for you're going to get.

  

  Theoretically you could do with a unit of the M series, because they have the ability of/s digital correlated (timed by the hardware).  You will have to implement the whole of the Protocol in the software yourself.  All up packets in the shape and alignment of the data will be done by programming, as well as addressing slaves. This would, of course, the overhead costs of any program running in Windows.  If you are interested in going this route, this forum should help you get started in the right direction.

• Can what cards I use to develop communication SPI with Labview?

  First of all, I'm an intern is currently working on a project that involves communication with an SPI interface. I have absolutely no experience with SPI, but I finally decided to try. I work for about 6 months with labview and understand the function of basis of a large number of its resources.

  The problem:

  We want to connect Labview to an evaluation Committee that is connected to the PC via USB (but it can also be adapted to connect through SPI). The evaluation board mainly reads and writes if sign up for issuers that are connected to it by a Module assessment. The program which is already which is the Studio of SmartRF (that works via USB), but as we want to link all the functions in Labview we redevelop a platform to do so. If shortly, we want to make a Studio of SmartRF version in Labview. We want to be able to get all the information that makes the program and others... and all this is possible through SPI.

  Here is a link in case you are interested what is SmartRF Studio: SmartRF Studio link

  My question is which card do you recommend for what we are trying to accomplish? We are looking for something not very expensive but who fail to meet our requirements.

  I think of the NI USB 8451, but please make suggestions.

  Thanks a lot in advance and please stay tuned to my many questions coming about how to accomplish this enormous task with no knowledge whatsoever of SPI or how to mix with Labview only one student. I am reading as much as I can find, so all the links will also be very much appreciated. If anyone has any experience with NI USB 8451 with Labview be kind enough to guide me

  Sincerely,

  Gisela

  If you have very little experience with LabVIEW and SPI, the 8451 is a good choice. It's expensive, but it's really easy to use and configure.

  The Aardvark is also a good choice. There pilots LabVIEW is also easy to use in LabVIEW. The disadvantages is that it doesn't have a lot outside of simply making SPI or I2C - in other words, it doesn't have a lot of GPIO. This can be important when control of multiple SPI devices, because it requires to select them lines individual slave.

  Dinah is really more than a product of laboratory, or something that is meant to be placed inside a camera. It is expensive, compared to the other two, but it doesn't have native drivers in LabVIEW. On the contrary, it comes with a DLL you can call from LabVIEW. I wrote a set of LabVIEW drivers for it, but I can't distribute.

  There are other products on the market, which some will resemble a device series to your computer. For example, you would use VISA to communicate with the SPI controller, and it would appropriate communication of SPI.

  Among the three mentioned here, I would suggest that you go with the neither of the Aardvark, one.

• Robot with arm joint

  Hi people.

  I'm looking for a with several degrees of freedom robotic arm to hold and tilt an object (s).  Objects would vary between about1' x 1 "x 0.1" rectangular objects to maybe length 6 "x 2" diameter cylindrical objects.   Weight of objects can be a maximum of 20 lbs.

  Robotic arm must be able to withstand up to 225 kV x-rays.

  I would like to be able to control such arms with LabVIEW movement solution any.

  I know that it is a difficult question but looking to see if maybe someone has an experience that can help.

  Sincerely,

  Hi Don,

  You can take a look at ImagingLab Robotics library for LabVIEW - http://sine.ni.com/nips/cds/view/p/lang/ru/nid/211183
  These libraries allows you to use LabVIEW for control of almost all industrial robotic arms produced by Denso, Epson, Kuka, Kawasaki, Mitsubishi, Toshiba and Yaskawa Motoman.

  You can choose any robotic arm 7 robot manufacturers according to your budget and your needs (in your case, the arm must be able to work in dangerous places). I recommend you contact the local representative of the selected manufacturer or visit their Web sites.

  I would like to know if there are a few tutorials and code examples on communications with devices:

  How to write you SD card?

  How to use CAN, SPI, I2C and UART?

  How to use the OLED?

  Is it possible to use the FIFO memory with labview ARM and how?

  Is it possible to target the daughterboard with Labview, this Board includes a processor LM3S2110?

  How communicate between a time critical Vi which runs on the ARM processor and not time critical Vi host that runs on the PC?

  Thank you very much.

  Your Neil

  Hi Neil,

  How to write you SD card?

  The SD card slot only is not currently supported in point 1.1 of the ARM.  The next version of the ARM should support this device.  Once this is the case, you can access the SD card using the primitives of e/s files.

  How to use CAN, SPI, I2C and UART?

  I found an example of UART in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > protocol drivers > Comm.lvproj series.  I will attach also a project that uses CAN communicate with the LMS2110.  As for I2C/SPI, I suggest experimenting with the screws for this (located on the ARM > palette SPI and I2C) and consultation of the other threads on the use of these screws or create another thread.

  How to use the OLED?

  There is an example of this in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > Device Drivers > OLED.lvproj.

  Is it possible to use the FIFO memory with labview ARM and how?

  FIFO on ARM is very similar to the desktop.  These screws are located in the data Communication > synchronization > FIFO pallet in real time.  There are several examples on how to use these FIFO on ni.com.

  Is it possible to target the daughterboard with Labview, this Board includes a processor LM3S2110?

  You can provide this Commission with CAN, as shown in the attached draft.

  How communicate between a time critical Vi which runs on the ARM processor and not time critical Vi host that runs on the PC?

  See the related example. RT FIFO If you use the FIFO screws I mentioned above, you should be able to do something similar.  I suspect that the FIFO is used to communicate between a critical time timed loop and while loop a criticism.  The while loop would then use TCP/series (or even shared network variables) to communicate to the host.

  Good luck

• LM3S8962: SPI clock problem

  Hello

  I'm working on a project using the star LM3S8962 evaluation kit and a 4-channel analog digital converter 24-bit Texas Instruments ADS1274EVM.

  I want to get the data sent by the ADC with the LM3S8962 using the SPI bus.

  I have all of the example provided by the following link for my case: http://decibel.ni.com/content/docs/DOC-7701

  The ADS1274EVM provides 2 pins for SPI communication: DOUT1 and SCLK.

  When it becomes a clock on the SCLK pin, it starts to send data via DOUT1 pin, there is no pin slave select.

  If I'm right, I don't have to connect:

  -PIN SSICLK for the LM3S8962 with SCLK of the ADS1274EVM pin

  -PIN SSIRX for the LM3S8962 with the pin of the ADS1274EVM DOUT1.

  The ADS1274EVM is powered independently of the LM3S8962, so I connect VA WINE GND as shown on the http://decibel.ni.com/content/docs/DOC-7701page.

  I write because it does not work: the ADS1274EVM sends no data given that I cannot get a clock signal of the SSICLK of the LM3S8962 pin that allows the ADS1274EVM start the conversion

  I think that him 'ARM of SPI create Configuration reference VI' configures a clock that is sent through the LM3S8962 SSICLK pin, but it does not work as expected.

  Can someone help me please? Thank you

  Luke Y.

  Hi Luke,.

  I just tested the example and had no problem generating a clock on SSICLK.

  I join the project I did with LV 2009 SP1. I hope that you could test and tell us if it works.

  Kind regards
