Searhcing buffer

Hi all

I got a simple stamp that I use to store the read data from a serial port, I scan the data in the buffer for a string that is specified by the user, if the string is the loop is stopped, data written to a file and the next step in the process is done, if she's not here, he continues reading the serial port. If the data in the buffer exceeds 10,000 bytes without finding the chain. The buffer is emptied into a file, such as the user wants to see the data after executed tests. This continues until the string is found. I can often end up with more than 200 k files.

The problem I have now is that I have sometimes "miss" the string, this seems to happen because the first bit of the string is found in the file and the second bit between then in the buffer, but because the string is not terminated the program obviousy ignores and think that it has not taken place. I know that the string is deffinatly be found because once the hours of program on the full string is in the file.

Any ideas to stop what is happening will be greatly appreciated

Hello

One solution could be that you keep an adequate number of read characters in the buffer so that you do not lose the beginning of the string you are looking for.

  • How can I stop firefox in delay/suspended momentarily (5-10 seconds) when I try and a large video/application of buffer?

    Hello

    When I try to buffer a large video (youtube HD) or the even more lag - to perform a speedtest

    animation for speedtest occupies about 3 images - about 4-6 seconds apart, as with youtube, he puts in buffer 2 seconds - then firefox hangs for about 12 seconds - when he comes back he is fully buffered

    has raised this issue since I got new Internet (download 76mbit) and it is not my rig like youtube and speedtest.net run perfectly smooth in chrome (but I don't like chrome or the google customer support)

    Hey Buddy

  • Y at - he shortcut keyboard to take a screenshot and at the same time put in the copy/paste buffer

    My question: is it keyboard shortcut to take a screenshot and simultaneously place the content in the copy/paste buffer, rather than a file?

    If not, is there a shortcut miss me.

    My current approach is Cmd-Shift-3 or Cmd + Shift + 4, take the screenshot, open in preview, select all, copy, return to remove Word, paste, the screenshot file, then repeat. There must be a more efficient way to work.

    Thank you

  • Fix buffer overrun on Tecra A8-103 Vista key

    Hi all

    Please can someone help me with the following. I bought Tecra A8-103 a few months ago. Everything was OK until a few days ago when I pop up error message whenever the mobile VODAFONE UMTS connection is made:
    Quote
    Microsoft Visual C++ Runtime Library
    Buffer overrun detected!
    Program: / Vodafone Mobile Connect/Bin/Mobile.exe
    A buffer overrun has been detected as corrupted the program's internal state. The program cannot continue safe execution and must now end.
    End of quote

    I must say that this connection works correctly since may ' 07, when it is installed.
    I have contacted Microsoft, watched their support forums, but so far there is no help.

    Thank you.
    Claudio.

    Hello Claudio

    Vodafone any which comment to that? Maybe their support a clams a lot about this? Have you tried to roll back the OS to an earlier time using system restore? Perhaps it may be a quick fix to this.

  • HD movies play perfectly, BUT the Extras repeatedly buffer

    Hello

    As a general rule when I discover an HD movie on my MTB from the iTunes Store it plays almost perfectly.  No complaints.  But whenever I try to view all extras included, I constantly experience very slow downloads and content buffering.  It is so predictable that it's almost very bad.

    If I didn't know better I'd guess that Apple is in order of priority the Extras below original HD, resulting in slower outgoing movies band bandwidth every time the content is stored on their servers.  Otherwise that it's as if the Extras are much larger files or something.  But it's just the HD resolution as in the movies and just TV shows?

    Why all the video content Extras would play so much differently, buffering repeatedly and download much more slowly than the HD movie?

    I can even stop the extras to play the buffering and immediately play an HD movie that plays instantly without any hitch.  Then go back to the Extras and boom, slow, city of the buffer.

    FYI - my ATV is connected via an Ethernet connection to the modem it is clean and we have incredibly fast internet access.

    Very annoying and I have practically stopped watching the extras for this reason.

    Thank you

    Works fine for me, you can test it on another network

    Hello

    I have lurked around a bit and it seems that your drive has buffer of 16 MB that is absolutely definitely sure. To check the details of your computer, you can use the tool "Sisoft Sandra". You can download [url href = http://www.sisoftware.net/index.html?dir=&location=downandbuy&langx=en&a=] here [/ URL].

  • Satellite A75-S209: How can I set the UMA Frame Buffer of 256 MB

    Hi people

    I have a Toshiba satellite A75 - s209
    With: 3.06 GHz, 768 MB Ram DDR. ATI Mobility Radeon 9000 IGP...

    I just bougth (Test Drive Unlimited) a game, it needs 256 MB to grafik.

    Can I upgrade my 256 MB UMA Frame Buffer?
    At the moment I can only set it to 128, is there something I can do to get it to be 256 MB?

    Henrik

    Hello

    According to the Toshiba site we the notebooks graphics card supports up to 128 MB shared memory.

    Unfortunately, it seems that you cannot increase the amount of memory. Buddy is not possible, it s a simple hardware limitation!

  • I would be able to increase the UMA Frame Buffer if I increase the MBofRAM?

    Hello world! (Me again!)

    I was wondering if when I get a 1 GB of RAM I will be able to change the size of the UMA frame buffer memory? (for example, 256MB RAM - frame buffer, 512 MB of RAM of 32 MB - 64 MB frame buffer and 1 GB -?

    Thanks in advance!
    Thank you!
    Suddste

    Hello

    As far as know not that the size of the memory is not decisive for the evolution of the AMU.
    More important, it's the video chipset which is integrated into the motherboard itself. This chipset allows you to use a portion of the RAM for the frame buffer.
    This is called unified memory architecture (UMA).
    These settings you can change in the BIOS, and the highest value AFAIK is 128 MB.

    Good bye

  • Sound / Audio (CRAC, pop, broken playback) the buffer Y460P issues

    Hello

    I have problems playing audio without clicks and pops. They sound like problems of buffer against the recess.

    Clicks occur during audio playback of any program, but worsen under certain cercumstances.

    The worst time is when I have my external monitor plugged. He actually 10 times worse if I have uTorrent with multiple files running. Even after closing, the clicks remain. The best result is obtained only after the closure of the programmes as much as possible.

    The clicks are better, but not completely disappeared, when no other monitor is connected and cover is open. If I close the lid, the clicks well gets worse.

    I have an external USB sound (Sound Blaster X - FI) card and also tried with this. It makes no difference, the clicks are stll there.

    I updated my BIOS with the latest version and sound card drivers are updated. Is there anything else I can try?

    Thanks and let me know if you need more information from System.

    In addition, about drivers Toshiba download page, I can't P105... There are some P100 and P200, no p105. Is there a way to get around this?

    Hello
    Unfortunately it s is not possible. So I think that it s increase/reduction of itself when you change the amount of RAM in your system.

  • How to structure the DMA buffer for SMU 6341 DAQ card for analog output with different frequencies on each channel

    I use the outgoing/incoming analog DDK with the DAQ 6341 SMU map.

    The examples, for example aoex5, show a single timer (method outTimerHelper::loadUI), but the example shows the DMA loaded with same size of vector data.

    There is a comment in the outTimerHelper:call rogramUpdateCount, which implies that memory sizes different pad per channel can be used.

    (the comment is: switching between the sizes of the various buffers is not used)

    Nobody knows what should be the format the DMA buffer for data from multiple channels with different frequencies?

    For example, we want a0 with a sinusoid at 1 kHz and a1 with a sine wave of 1.5 Khz.  What looks like the DMA buffer?

    With the same frequency for each channel, the data are interleaved, for example (ao0 #0, ao1 #0; ao0 ao1 #1, #1,...), but when the frequencies for each channel is different, what the stamp looks like?

    Hello Kenstern,

    Data are always intertwined since each card has only a single timing for each subsystem engine.

    To AO, you must specify the number of samples that will be released to the AO. You also specify the number of channels. Because he didn't is that a single engine timing for AO, each AO will be channel will be updated at the same time to update clock tick. Data will be interlaced exactly as shown in the example because each channel AO needs output at each tick of the clock to update. The data itself can change depending on the frequency you want to copy.

    In your example, you must come with an update rate that works for the two waveforms (sine waves of 1 and 1.5 KHz). To get a good representation of a sine wave, you need to update more than 10 x faster than your fastest frequency... I would recommend x 100 if possible.

    Update frequency: 150 KHz

    Channels: 2

    Then create you stamps that include complete cycles of each wave you want to produce based on the frequency of update. These buffers must also be of the same size.

    Buffer 1: Contains data for the sine wave of 1 KHz, 300 points 2 cycles of sine wave

    Buffer 2: Contains data for the sine wave of 1.5 KHz, 300 points, 3 cycles of sine wave

    You can Interleave them as before. When the data are performed through the ADC, they are out different sine waves, even if the AO channels are updated at the same speed.
