Acquisition of data ongoing and finished at the same time

I have a reading program in the measurement of the temperature of thermalcouples and I currently have my system set up to take a finite number of samples.  During the acquisition, I am unable to see the data in the front panel and I want to put in place a way to visualize a graph of continuous for my data waveform is sampled so I can look to find errors.  Is there a good way to do this?

You cannot view the data until it was acquired. It is the programming of the acquisition that is at fault. If you want to see it sooner, change the number of samples or the sampling frequency. With a graphic instead of a chart, you can simply change the number of samples and get a continuous display.

  • Why can't acquire data from strain and resistance at the same time with a NI 9219 module?

    Hello

    I use a chassis with a NI9219 module 9172 cDAQ to try to acquire the strain and resistance at the same time, with the Labview SignalExpress software.  Is this possible?  When I try to display two values of signal at the same time, I get an error of assistant DAQ 50103 'the specified resource is reserved.  The operation could not be performed as indicated.  I used to be able to acquire the strain and tension at the same time, but now even that gives me error 50103.  I have hours trying to figure this out.  Any help would be greatly appreciated.

    Thank you

    That's all!  Thank you very much, now I can sleep tonight - seriously!

  • USBOTG and Charge at the same time on Stream 8

    To keep this thread as productive as possible and efficient for those who find it useful to:

    Unless you have under your eyes

    1. a schematic representation of the 8 Stream USB port (USB port and battery electric circuit etc.)

    2 source code for the firmware BIOS and kernel that controls the material

    Please DO NOT respond or say "is not possible".  In view of the above is true, you do not have enough information to say '' not possible. ''

    If no one replys with a solution, what he calls not possible by default.

    Also please do not answer to say ' I don't know how "or" but I know how to do anything else that ' is also not that useful.

    An update of the BIOS or other software update may be required by HP, Microsoft or both to offer this feature really intuitive and quite possible.

    And I hope that this thread can be an effort consolidated by all who have the 8 flow to make the necessary changes.  The majority of the other tablet PCs are capable of it.  It seems that only the 8 Stream and a few others have trouble with her.

    ~~~~

    I want the ability to use a simple, inexpensive cable and perhaps standard (with electronic active minimum inside) which allows me to host and to use one or more USB devices on the Stream via its USB port B microphone 8 while this cable can also be connected to a charger standard and charge 8 flow simultaneously.  This means that the cable has a minimum of three connectors.  One of the possible configurations are as follows (apart from the normal charging cable):

    1 cable Micro USB B Male - connect to the stream 8

    2 USB male A - connect to the AC charger (IE one that came with the 8 Stream)

    3. USB A female - one or several connectors to plug into the key of USB data, keyboard, mouse or even a hub.

    Connector # 2. above shall provide a power supply to recharge the 8 Stream via conn. #1 and the power supply for external USB devices via conn. #3 so that they are in use - all at the same time.

    A and if the same cable can act as a normal OTG no charger for when no external power supply is available.  This may necessitate a switch or an electrontics active inside.

    The last part of this goal is unimportant for various reasons.  I wish that HP, the manufacturer of 8 flow, to State in writing good mode necessary to do this, so that other manufacturers or even-it yourself can make maximum use of their tablet HP equipment.

    ~~~~

    The neat thing it will alow a person to do with their tablet, it is to work at home using the Tablet as a desktop PC by connecting a keyboard, mouse, perhaps external screen (with USB to the display adapter) and knit for a long time without time limit prescribed by the battery life because the charger provides energy to all involved.

    If there is only a single connector on the cable #3, then an additional node of coarse had to provide support for these multiple USB devices at the same time.  However, it would be better if there were several #3 connectors integrated in the cable itself.  This would be better as a suitable USB hub also requires its own power.  That an adapter is necessary if the whole thing were integrated into one.

    ~~~~

    I really want answers from anyone who has already accomplished USB OTG delivered with simultaneous load with flow 8. (independent of any published 'proper' way is also welcome)

    Today's date is 2015-01-16.  If in 2015-02-16 (one month), nobody has posted a solution and then starts to bug HP and Microsoft on it's us?

    ~~~~

    Technical training:

    I understand the possibility the tablet software and firmware must take a decision on the manner in which power flows on the power port USB microphone B pins.

    I know that with a proper design of the electronic circuit carring these signals of power inside the Tablet could be sensitive to what is connected and without risk to decide for himself what to do without needing to control software.  For example by testing/detecting periodically differential voltage or current management to see what sides of the connector can supply.

    But this is only one of the many "could bes".

    In addition, this can be no standard regarding the standard USB.  What seems to be actually the case with a lot of cables OTG + fresh, is that physical clues embedded in the cable or charger are used to signal to the Tablet what the situation is.  Then the signal of software/firmware of the Tablet, interprets what the situation is intelligently and responds by flipping the bits of correct hardware control to activate, or deactivate the power flow in the port and also control its direction in or out.

    I'm not familiar with the standard USB.  Maybe I could do more research, if I believed that HP followed with 8 Stream or even the standard covered this situation explicitly.

    But to a certain extent, it seems I'll have to invent something that should be intuitively just like it does with other tablets. Isn't it?  Maybe I'm overthinking, but I can't find any USB OTG + cables load that specify compatibility with 8 HP flow.

    In any case, I was familiar with both methods other use of tablets to send the highest mentioned signal to the hardware/firmware/software of the tablet to the idea that it's time to load / time of OTG or both.

    The first method is a 0 Ohm to 200 ohms short between pin USB A 2 and 3.  This is the bidirectional data differential lines D - and D + respectively.  In data mode, all the data passes back and forth on those lines.  When you load with a cable, it's the charger module that puts this short, not on the cable.  I measured the short on three different Chargers.  It is 0 Ohms on two of them, one of those who are the charger that came with the 8 HP flow.  The others 0 ohms was generic.  The third was for an apple iPad and it measured on 53KOhms.  It's probably not the resistance ohms 0-200, but probably it is impedance termination indicating that there is some intelligent serial port communication in the charger itself.  Leave it to Apple to be different.

    This method is somewhat questionable, as this signaling mode would prevent OTG + fee because it seems unlikely that you will be able to OTG when the data lines are shorted each and overloaded with such low impedance.  I could be wrong on this subject...

    The other method I have seen suggested to work with some tablets and phones other than the 8 stream is too short the USB microphone B pin 5 to Terminal 4 with 0 Ohms to 100 000 Ohms.

    USB B has 5 pins.  USB has only 4.  The extra pin on B moves the GND pin 4 pin 5 pin to and makes pin 4 PIN ID.

    If this signal applies to a drop in the ID pin (4) or in some cases, I saw that she proposed, he runs down with 0 Ohms.

    Dead shorting things always makes me nervous.  If ID is a simple normally high impedance high input, resistance could be used to make voltage well below the low or zero threshold while also preventing the risk of damage when cheat on him with a device that you do not have the diagram for.

    Yet, 100K is a bit high for a 'pull down' in most of the situations that I'm used to.  Even a 10K would be uncertain. A 1 K or 2 K seems reliable enough, but then things are weaker and in know more nowadays low...   All but a dead short but if possible.

    So, it seems possible that the device might be able to "indicate" by the specific value of the resistance, which can be found here.  In other words the resistance is not a pull down but in fact a signature analog ID, in which case the exact value will be crucial. So if this is the case, a guess is not going to work.

    Obviously in such a system as described above, a chip inside the Stream 8 should be responsible to support this information. I hope the 8 Stream has such a chip.

    Probably a register inside this chip would be at all times what the State of the pin ID is a binary number.  All that is needed is for the BIOS to the chip and the registry in it and read this number via the bus to determine what happens to the port. Finally, he would use that signals of info to send the order of material to the electrontics of power set the appropriate direction to take etc.  (and change the State of the icon on the screen of the rude)

    I don't know if the PIN ID method described is a standard USB or not either.

    Eventually, there may be a third way. But I do not suspect that it would be possible with a non-active external device. In any case too complicated for the novice DIY for sure.

    The device would need to act is a kind of extension of bus.  As an active hub.  But she would use the negotiation of data USB serial lines and in addition to reproduce one or more additional USB ports, intelligently inform the tablet to get with the program which is "now we're going to otg and recharge at the same time."

    This requires a smart external device with a processor Inside, no doubt.

    It seems to me that many other tablets have been able achieve avecjoint here the need for a smart external device and thus the flow must also be able to do.

    There is a device that claims to be able to work with the HP Jet 7 and 8 and provides same ethernet and USB and big DVI ports so loads the data stream.  But its expensive because it is active.  Se here:

    http://AMZN.com/B00OVDE0GC

    It's called a "Docking Station".

    A reference to a product that does exactly what I want (possibly without active electronic components) is here:

    http://AMZN.com/B00LTHBCNM

    It's by Kirin and it is a device of type squid with four USB ports.  Precisely, which is my goal.  But read in the comments stream 7 user indicated that he would not be OTG and load, not really clear if it worked as a hub USB OTG or not.  Another evaluator stated that she would not support even a single USB device much less fees of 8 Stream.  This device has a switch.

    I forgot to mention that some 'hackers' have claimed success with other tablets to deceive their devices by using a multi-step process to plug things in.  Usually in general they would get connected Tablet and load first, then they would return a switch or something remove some resistance or the signal was introduced by the first position of the switch. For some reason any Tablet would continue to require. Then the data lines would be free and they would plug in a usb key and it mounts correctly even if the tablet was always in charge.

    It's like the power circuit has a lock which does not allow it to return to the mode "power flow" as long as he still feels the power flows inward regardless of what software it is telling.  Full proposal here.

    These tips seem dubious to me.  Changes in the BIOS could change the way it works.  Also you can not be sure what actually happens if you do not have a schematic representation.  You could damage your tablet.  Many people will support icon in the operating system whether the Tablet is in charge.  But I'm sort of a low-risk guy and my policy is generally indicators of intereperet not to have meaning at all once a device is functioning in a non-standard setting.  Especially when it's something that I did not built and could not fix if I FRY.

    Hypothetical reasoning: tell me what data sensory discs really the State of the charging light screen?  This reflect the bit of hardware control programs actually feeding management and status on the port?  Or does it measure the direction of the flow of power, said in the section of the circuit battery monitoring?  Point - none of us have a schema because it's owner. To really be sure according to the smart electronic hardware, the port must be mode flow under advisement "of power. If it's in a "power flow out" mode and power will be delivered externally as well you wind upward with both power supplies the same power at the wheel nets.  In this case, the two opposing regulators attempting both to drive 5 V can have slightly different voltage calibrations.  That could lead to fighting between them, with more than 100% of their capacity.  For example if you try to regulate 4.95 real V and the other and other attempts to regulate 5.05 V.  Current then flows to the tune of 100 mV / a few milliohms in the cables linking the two.  This may be several amperes. (many)  In other words, like I said: you want the tablet to know that power is coming in don't go out and automatically hitting the internal switches needed for that to happen. Probably the icon should indicate this with precision, but in some wacky situation, he could not. There may be a chance that the icon could indicate the load and still be burning or focusing on some circuits of the tablet or the charger.

    Another thing, I could see that happening is if you play with these reported resistance types enough you might find a resistance value that winds up place the device in an intermittent condition.  In other words it keeps flipping back and forth quickly between OTG and fresh.  It can give the illusion that it works.  You can have marginal communication with your USB devices and battery could even load.  But will still be a lot of stress on the power circuit.

    It is difficult for me to risk a Tablet perfectly well if I don't know exactly what I'm doing.

    If a brave individual makes their own experimentation and verifies that it charges and OTGs and you tell the rest of us, you're a hero.

    Maybe one of you has a good knowledge on the USB standard to have more confidence in such an experience... like what the ID pin 4 REALLY supposed to work for example?

    That's what I know so far.  If you think you can help, thanks in advance, or if this helped you, then your quite welcome.

  • Questions about serial port read and write at the same time

    Hi I create a user interface for the communication serial port, where there are essentially 2 front panels, where the user enters commands one and the other where the prints of UART is delivered. I thought initially using a state machine but the reading and writing may be independent sometimes and so I can't rely on States. I searched a bit on the forum and he left me even more confused. Help, please.

    (1) in a thread that sessions visa duplicated has been used for writing and reading at the same time, is it recommendable? How will this affect performance?

    (2) essentially when the vi is reading data are it must constantly view as well, however, someone said that it takes too much memory to use shift registers, so how do I go about this? If using a State in queue after the loop of reading it affects the playback loop and be sequential?

    In addition anyway is to move the cursor to the latest data from the indicator

    (3) for the control of the user input, assumes that the user has entered an order in the control and press ENTER, then writing visa is launched, but if it comes in another string and press enter then write must be called again... is - it possible? will detect the previous commands in the control of compensation?

    (4) according to my understand the expectation for the event do not monopolize resources and writing can go in parallel, am I right?

    Thank you. I have attached a very basic vi which took me to the point, but I want to make it more robust. Please help especially in the part of the user interface.

    su_a,

    (1) you can have only one session to a port. Several UART can handle full duplex so performance is not affected.  At flow rates of high data and large amounts of data, buffering and latencies of BONE can become a problem.

    (2) who told you that shift registers using too much memory? Shift registers are usually the best way to transfer data from one iteration to another. String concatenation inside a loop (registry to offset or not) causes the chain to develop and may require re-allocation of memory.  Your VI never clears the string so its cold length become very large.

    Generally, you do not have an active cursor on an indicator.  If you want to always display the most recently received characters and turn on the vertical scroll bar use a property node to keep scrolls to the bottom.  This can be annoying for users if they attempt to manually move the scroll bar and find that the program continues to move it back automatically.

    (3) if the user has changed the value in the chain of command, when he hits enter the modified value event fires.  Simply strike brace does not change the value and does not trigger the event.  Not control need to be erased, but the value that he has to change.  If you want to send the same command again, have a button send a command may be a better choice.

    (4) write is a case of the event.  It is not in parallel with anything.  The structure of the event do not monopolize resources.  The other loop will run while it waits.

    The event loop will not stop when you press the STOP button. Probably it wll take two command: change events of value after JUDGMENT before any loop stops.  Replace the Timeout event (which never expires) with a STOP: value change event and a real wire of this judgment to the Terminal endpoint.  Remove the local variable.  Make mechanical locking when released.

  • Satellite M30X-122: how to use the headphones and speaker at the same time?

    When I plug the headphones into the Jack, the speaker is created off the coast of the moment.

    Thank you
    Peter

    Hi Peter,.

    There is unfortunately no way to use both headphones and speakers at the same time. This is because tghere's a disconnection physical power for the internal speakers when you plug in the headphones. It is not by software. The only way around this would be to dismantle the headphones Jack and solder connections that are broken when you insert the headphone permanently.

What we do when she wants to print something, it is transferred to an SD card, then put the SD card in the office and printing from it.  Aging.  It would be much better if she could just walk into the 'office' and turn the printer on and print directly from his laptop.  I like to keep the printer connected to the desktop also.
