• On the HDR-XD550 buffer overflow error

  I had my handycam for over a year and only used a few times. We took it to the Disnyland and we got the video and great photos so she went in a padded case and was not again for 6-7 months. In the middle of registering my program of school kids that I have received a "buffer overflow" message and recording stopped. I was not able to record more than a few minutes since then. I read about this problem on several websites with the same model correct. Of course, Sony wants me to pay hundreds of dollars to watch because it is just over a year. Technical support even says she has heard of this problem with the other appellants, but Sony will not determine whether a recall. I spent a lot of money on what was supposed to be a quality product, and if it was because of something I did, I have to pay for the repairs, but many, many, many others have the same problem.

  Hello and welcome to the Discussion Forum for the users.

  I'm sorry you have a problem with "buffer overflow" appear on the LCD screen and the recording stops automatically. I couldn't find the model HDR-XD550 in our knowledge base, but I assume you have a model of Digital Camcorder HDR-XR550 hard drive. The "buffer overflow" error may occur when the camcorder detects the shock of the continuous noise or whipped milks, and internal protection system is activated to stop the recording on the hard disk. When recording in an environment that has continuous sound hard or milk whipped, as in a concert hall live or on a bike, please keep the camcorder from the source noise or shake as much as possible.

• How better to apply a data serial port FIFO buffer?

  Hello

  I think I'm missing something very basic, so, please forgive my ignorance. All I want to do is to establish a simple FIFO buffer that has a logical sequence of quality control before the display of the data on the screen. I can't understand how best to continuously browse incoming data.

  The attached vi should explain much of it. My 25 bytes per second through the serial port of watercourses of the instrument. I heard it is best to put the VISA reading outside the loop, but I can't get my vi to read constantly new data if I do this (it stops at the length of the buffer specified).

  Is a possible solution to properly use a feedback node?

  Thanks for the help. I use LV2009.

  This is the procedure of package as you can see, then add it after

  BEGIN
  

  Or you can add this command before call you the procedure.

  In my view, the use of the output for the large amount of logging information is not good idea.

• LabVIEW buffer overflow error

  I'm using LabView 2010 and everytime I go to collect data using my VI, after a few minutes of data, I get a buffer overrun indicating error, and stops data acquisition.

  How can I get to stop this?

  Also, my VI is configured to 10 samples per second and an average of these output 10... then I need 10 averages per minute. It does not appear to be part correctly. Can someone tell me how to fix it?

  Start by getting rid of all xvis I think I showed that this code serves no useful purpose. Do not. Replace them with all the functions, just throw the blue icons. CTRL Space ctrl r. gone poof. The rest will work out pretty easy once these pigs is no longer slow down useful processes.

• How to periodically send various types of data via the Serial Port?

  Hello! Everyone

  I have to send data to LabVIEW to my device on the Serial Port.

  I know how to send data on serial port in LABVIEW, I already have this part.

  Now the problem is that I have several types of data I need to question my embedded device, if I want to send the query periodically command.

  So lets say that my four Op Codes are the following, which will send four different types of query command to my device on the serial port.

  (To be honest only OP_LED and OP_SENSOR is used now)

  0, OP_SYNC

  1, OP_LED

  2, OP_SENSOR

  3, OP_FUTURE

  Structure of basic package is as follows:

  Header (0x2C), Checksum, length of the data (n bytes), Op_Code (1 byte), length (length of Code + data Op)

  For OP_LED, I need to send the package as follows:

  0x2c 0x02 0x01 0 x 00 0x2F (0x2F being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

  Length of the package this is 0x02

  0x01 is Op Code for OP_LED

  In the same way

  For OP_SENSORi need to send the package as follows:

  0x2c 0x03 0x02 0x00 0 x 00 0x2D (0x2D being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

  0x03 is length of packet here

  0x02 is Op Code for OP_SENSOR

  So, how can I do this periodically in labview, in such sort that period can be adjusted whenever necessary.

  Is there something in LabVIEW to do.

  I had done the reception and decoding part and working properly.

  http://forums.NI.com/T5/LabVIEW/store-data-coming-from-serial-port-in-buffer-and-then-take/m-p/32722...

  So I must implement read and write the part of same while loop?

  Do not insert in the table if you put data in an array at index 0.  Just use array to build.

  No need to have Visa to write don't be a part of wire to the wire of reference and error VISA go in the upper part.  These wires should go THROUGH the entry VISA.

  Don't your checksum requires all the bytes up through data?  Righ now, you only put the checksum on data bytes and forget the opcode and length bytes.

  Your sending is not the opcode for Opsync or Opfuture.  You just send the empty tables.  At the same time for the other two, you put the opcode in the data table.  All your original opcode in the table build thread.  Get the data out of these structures in case item which is supposed to represent the opcode.

  xpress_embedo wrote:

  Now it works but I have now two problems.

  (1) OP_SYNC and OP_FUTURE do not data, but still receive its data on serial port, can I do something here as I have nothing when the table is empty in the structure of the case.

  I do not understand this statement.  Perhaps my answer above will fix any issue you have here.

  (2) how can selection operation Code to be send is done using control façade but real application, this task should be automated to a certain frequency, like OP_LED package must go out to the serial port to 100msec and packet OP_SENSOR must go out to 1000msec, I do this.

  Now you agree a little more architecture.  I would encapsulate the code that is in the while loop as a Subvi.  Then with the hand of your program while loop, use two time Express VI, a game for 100 msec, the other for 1000 msec.  When an express VI is true, run the Subvi with a command set waiting for the answer.  When the other VI Express is true, have it run the Subvi with the other set of commands.

  The device responds with anything when you send these commands?  You only send data.  I see no VISA Read to be able to recover all the data.

• Ignoring the buffer overflow

  Is there a way of 'ignore' the buffer overflow error and leave the buffer to be overwritten without having to close and the process of acquisition and retune the radio report?

  I know that the first question is: "are you * sure * you do not want to do? '... But yes, I'm sure!

  Hey Brandon,.

  I'm glad you asked on this subject!  We have just posted our latest driver OR USRP, version 1.3.  You can download it here:

  http://www.NI.com/download/NI-USRP-1.3/4711/en/

  One of the features of this driver is a new node property that allows you to cost overruns and overflows as warnings rather than errors.  "You can find the Configuration property' advanced search ' WARNING policy.  Then, you can wire the constant return warnings:

  

  Please note, after updating your driver, you must also update the FW and FPGA on your USRP image.

• Input buffer overflow Agilent 34970 has

  IM using Agilent 34970 A for a blood pressure purpose, Im getting error 521 and 103 when I select more than 15 channels.

  I understand that 521 error is an input buffer overflow error. IM using one of my own live measurements.

  I measured the 40 channels at once and I never had an error, but when I use the VI attached the error im.

  I reference some of the threads that deal with the same problem, I have not found a solution.

  Thank you

  Eureka

  Thanks for the reply... I thought about it... had to set the unit in XON/XOFF mode so that it retains the values of the power input channels. I did notice that I made the changes in the configuration, while I was doing someother changes...

  @margasan,

  The post that you directed me was one of my own messages... but thanks anyway...

• Time GPS, Position, Velocity.vi - error-1073807360 reading was held at node (arg 1) .vi property VISA set up a Serial Port (Instr)

  We receive information such as the Latitude and Longitude of a receiver Garmin GPS18xLVC via a serial port on our PC using LabView 7.1.  Successfully, I connected the GPS on the serial port and tested with HyperTerminal.  I tried reading GPS time, Position, Velocity.vi several times and still receive the following error message: error 1073807360 has occurred to the property node (arg 1) visa configure a Serial Port (Instr) .vi.  I think it has something to with the configuration of the VISA series under vi.  Any suggestions would be greatly appreciated.

  Thank you

  I understood the question, that I had with the time reading the GPS, the Position, the Velocity.vi.  The vi. "do not open" port com automatically and so I had to modify the NMEA GPS Subvi reading to first open the port (VISA open command) and then continue with other operations.  Once I did this it started to work very well.  I don't understand why this feature has been left out because it won't work without it.  I tested the code with a receiver Garmin 18xlvc and it seems to work fine.

• Parity errors &amp; read on Serial Port framing

  Hello, I am writing a program that reads the serial port IR thermometer. Intermittently I get parity so many framing errors and can't explain why or find a way to remedy. All the parameters of the series were double checked and controlled. I don't get any errors when you use HyperTerminal yet, when I do test bed in MAX, I see these mistakes from time to time. I tried the suggestions of the knowledge base for these as presenting a delay between the Visa set up and read the Visa or flushing buffer issue before reading, but none worked. Any idea or ideas would be appreciated.

  In addition, while searching through discussions on parity and framing errors, I saw a when a user recommends the following: "use wait event triggered by the stop character and when the error occurs, I just deleted the error, empty the buffer (wait the next stop character) and reread." If that sounds like a good solution, how would I go about its implementation?

  I've attached a screenshot of my reading series loop so you can see what I'm doing. I do about the error code control timeout is.

  Given that you have activated the stop character, you should not use the bytes to the serial port. You shouldn't have to delay or any function buffer flush.

  PS, You also have to change the way your loop exits.

• Serial port buffer - how to read the last entry?

  Hello

  I'm trying to read data from a device connected to the serial port. The instrument makes a row of data, last updated CR LF at pre-set intervals (0.2 seconds, 0.5 sec., etc.). I want to read the most recent line to an interval of time different (for example 1 s). What happens is that the buffer fills, and when I read that I always get the whole buffer content, starting with the first (oldest) row of data.  After reading, I empty the buffer to prevent overflow.

  From the red string I, I serach occurrence of CRLF and take the data before the game. This will give me the first line of data (oldest), sometimes incomplete.

  What I want is the last line. There must be an easy way to achieve this?

  I can't use the Frother with my instrument.

  Any help appreciated
