• How to stop the Apple Watch finished my training in outdoor cycle automatically when I hit the break (with the intention of resuming)?

  When I use the external development of cycling in Apple Watch and I stop to use the restroom or coffee and the trip a pause, a moment later he (without any input from me) will complete the activity. It's very frustrating because I'm trying to get a new badge for most cals burned on cycling but obviously impossible training if I'm trying to break the journey at any point. If anyone else has experienced this?

• To use the external clock for SCTL myRIO

  Hi people,

  I'm trying to find a way to get a 2.5 PSM 16-bit ADC, TI ADS1602, to send data to the device myRIO. Ideally, I'd like to bit Records at 40 MHz in order to obtain the benefit of the PSM full 2.5. I know that I can create an 80 MHz SCTL on the FPGA to create a clock of 40 MHz, but when I checked the clock on an oscilloscope signal, it was obviously greatly degraded by bunch speed limits, so he looked more like a sine wave to a square wave. I doubt it would work for use as a clock signal to drive the ADC since ADC specifications say that eligible jitter is around 100ps.

  I can use an external oscillator to drive the ADC, but then I have to find a way to sync the clock with clock FPGA 40 MHz. is there any kind of PLL structure that would allow me to sync the clock FPGA myRIO to an external clock? Is there a way to do a loop simple timed cycle driven by an external clock? Or if I was able to customize the FPGA personality to accept a SPI signal up to 40 MHz (ten times her supported limit...), he would be allowed to use an FPGA to ~ 160 MHz and tell him to taste the SPI line each loop and proceed from there?

  Thank you!

  Hi 3.14159... ,

  The myRIO doesn't have the ability to import a clock to use on the FPGA block diagram for clock loops timed cycle unique (SCTLs). The sbRIO-9651 new coming out week OR (not shipping yet) is the only sbRIO who has the ability to import an external clock in LabVIEW. Many of our products FlexRIO also have this ability.

  Like you we have it, you can taste the signal at twice the frequency (or maybe more) to and wait an edge trigger to run a certain element of logic. "" "If you open the example Finder and navigate to hardware input and output" R series "FPGA Fundamentals ' triggers and guard dog" trigger detection, this gives a simple example to do this. Once again, since you are eager to taste 10 times the frequency of support, all bets are off, but it may be worth trying.

• Why is-DAQ-200714 fatal error?

  I'm having a problem where a system that works well for a while, with a good margin (rate of 1 kHz loop, 300uS PCL loop duration), suddenly throws the error-200714 and stops. I have the filter DAQ errors on, and it's performance that are linked, so why this closure of the system rather than increment on behalf of HP?

  Thank you

  The explanation of the error is "Acquisition has stopped because the driver could not transfer the data from the device to the computer's memory rather quickly. This was due to limitations of the computer system.

  Reduce your sample clock rate, the number of channels in the task or the number of programs on your computer that runs at the same time. »

  Hello Stephen,

  You get this error is because the program is not keeping up with the sample clock.

  I recreated this (outdoor VeriStand) by running the example of shipping single HW-Timed Point LabVIEW and increasing speed until I got this error. I actually got error-209802 several times before to do-200714. The first error is recoverable and I could ignore it and continue, the second execution stops when it is thrown.

  Error-209802:

  «DAQmx wait the next sample clock detected one or more examples missed clock of the device since the last call to wait for the next sample clock that indicates that your program is not keeping up with the sample clock.»

  To remove this error, slow down the sample clock, or else modify your application so that it can follow the sample clock. Alternatively, consider conversion errors affecting true property warnings and then assigned to the case of the appropriate warning. »

  Error-200714:

  "The acquisition has stopped because the driver could not transfer the data from the device to the computer's memory rather quickly. This was due to limitations of the computer system.

  Reduce your sample clock rate, the number of channels in the task or the number of programs on your computer that runs at the same time. »

  Based on what Jarrod mentioned above, the original error might be filtered by VeriStand judging by the part highlighted in blue to the first error. I suspect that the error-200714 is fatal because of the part highlighted in red above; the acquisition has ceased.

  If you monitor the DAQ system channel error, you see error-209802 so? Slow down the rate PCL resolve these errors?

  I hope this helps!

• Helps the workout App Display

  How to customize the app to drive to show me the heart rate, distance and calories status all on the same screen during an indoor workout?

  Hello

  It is not currently possible to display the heart rate, distance and calories status on the same screen when using the app to drive to record an indoor workout.

  Training app can currently view your goal and two metrics:

  • The metric of time (top-right):
    • This can be changed by tapping it, switching between the time of day and the elapsed time.
    • For inside and outside running and walking workouts, pace is also available.
    • For an outdoor cycling training, speed is also available.
  • The primary metric:
    • This can be changed by sliding on the side on this subject.
    • Depending on your type of activity, the choice may include: time, active calories, total calories, heart rate, rhythm, speed and distance.
  • The goal:
    • The objective can be considered as a ring of progress or for distance, calories or the time objectives, as a metric.
    • On your iPhone, in the application of the watch, go to: My Watch (tab) > training > turn on show metric goal.

  However, note that watch OS 3 - coming this fall / fall - allows you to view up to 5 parameters of training at a time without having to swipe: distance, pace, calories, heart rate active and out of time.

• Active measure of calories during the bike ride

  Hello

  I do a lot of road cycling and also use my Apple Watch to measure my fitness activity.

  I used the option open air training on rides Cycle and it seems good but drain the battery of the watch. I don't really it measure the speed and distance as my Garmin that does very well and is also linked to Strava, but I don't want the watch to measure my year, and the number of calories active.

  So, I tried cycling without starting a workout. The watch is a precise measure of the amount of time work, I exercised, but the number of calories burned seem much less than if I used a training to measure the same route.

  The question is, which is more accurate? A workout outdoor Cycle or while leaving the watch to do its own thing? I suspect the former. This then begs the question, how shows measure of calories burned.

  Thank you very much

  Phil

  Hi Phil

  The external Cycle estimate is more accurate.

  When recording a workout outdoor Cycle, Apple Watch esteem Active Energy (calories / kilojoules) using a calculation that is suitable for this type of activity. Apple has not released details of the calculation method.

• Jitter in response to signal generator of digital dashboard by using trigger nor tclk with digitizer

  I've written a VI that uses NEITHER tclk to synchronize a generator (PXI-5422 named FGEN1) and a digitizer (PXI-5122 named DIGITIZER1).  There is also a clock card TIMING3 generating a digital camera.

  It seems that can probably be explained by the way TCLK to synchronize, but I don't understand all the details.  Could someone help explain this to me?

  You are right. NOR-TClk ensures that all synchronized devices start at almost at the same time, to the same sample clock, with timing very tight. Sometimes, the level of synchronization with the devices OR TClk-synchronized beats at the level of the synchronization of the instruments of some competitor channels in the same device. But this is not free, there are compromises and added additional jitter for trigger response time is one of them. Here is an attempt to explain why:

  When you use NEITHER-TClk and send a trigger, the devices will respond to relax on the next cycle of the clock once made the trigger signal to the device. Let's say you have several devices all of them even configured with the same clock frequency. You block the signal of PXI_Clk10 using their PLL, so they drift out. But each unit's clock edge will be off, clock +-0.5 cycles. If you send a trigger to each of them, they will respond on the next clock cycle whenever it is, after the arrival of the relaxation to each device with different propagation times, whatever they may be. You get a single clock cycle of jitter on reaction of device to set it off.

  When you use NEITHER-TClk, several things happen: all devices are locked on the PXI_Clk10 signal to eliminate drift. The device clocks are then adjusted to a period level secondary clock. Very very tight. Then a clock signal common, slower called TClk is produced inside the devices. All the generation of trigger are delayed to be sent to the next rising edge TClk, and all consumption trigger is delayed to be received at the next front descending TClk. This way you make sure that propagation delays don't mean one of the devices does not react to the trigger until the next clock cycle.

  That's why you see jitter above the reaction time of relaxation. When you add devices with different clock settings, so the frequency of the TClk can be slower for a divisible frequency in the device clock frequencies everything is possible. This causes the trigger jitter of reaction time be even slower!

  I hope this helps you understand what you see.

• Hardware timed CI/CO, operation of PCI, I / AO with specific execution order

  Hi all

  I work with a USB-6361 NI data acquisition hardware and I'm writing a LabView 2011 program which sends a signal to my output device and reads several values of various measuring devices. I have a ramp voltage signal (in a table format) and I need to sequentially send the elements of this array on my AO device with very precise timing (ideally timed material). As soon as the value is written to the device of the AO, I need my tasks HERE and CI to record all available data and my task to send a single impulse before the next array element is sent to the device AO. All this needs very precisely timed such that if I perform a measurement on 1000 points in my table of ramp with a timing of 1000 Hz, the program will have exactly 1 sec. to run (less overloading caused in initialization and closing tasks) and produce a table of data consisting of 1000 steps of AI and CI. I had initially tried to achieve this by using a structure of sequence within a timed loop software, but because I won't get into multiple channels of Amnesty International and CI and tables of data, this has proved to be excessively slow. The other danger that I fear I could run is the case in which the LabView program runs more slowly than the process of acquisition data itself, thus causing data to write to the buffer and the measures being lost.

  I didn't spend a lot of time working with the procedures, timing and synchronization, so I apologize if this is a rather naïve question - I'm having trouble reconciling restrict them inherent software and order of execution with the hardware timing. What is the best way to solve this problem? I can only think of two reasonable approaches to the problem:

  (1) should I try to trigger my CI tasks and HAVE run on the completion of the task of the AO (and if so, how)?

  (2) I have the CI and tasks run on a separate clock with a start delay initial light as to compensate for these tasks if they occur reliable after that each value AO is sent to my device?

  Finally, I build an identical for a real-time embedded controller program of SMU-8100. The approach will be different in this case?

  Thanks in advance for your answer.

  I can give you an overview of the steps you'll need, but be ready to spend experiment a little time and some of these individual pieces of troubleshooting before you put them all together.

  First of all, a X-series 63xx allows all you need to accomplish a very precise synchronization in hardware.  When you then switch to a real-time controller, you must include an X-series device in the chassis to maintain this capacity of equipment.

  Second, 1 kHz is not yet a challenge to LabVIEW to catch up with your hardware, even with powered lower RT controller.  You just need to program the DAQmx tasks to let the hardware & driver do most of the work.

  1. I would dedicate a counter of the 6361 to generate the clock shared for other DAQmx tasks.  I tend to create a clock and operating cycle of 90-95% for this type of application of stimulus / response to the response time & maximum stabilization.  Generate the stimulus at the cutting edge of the clock and gain response data on the edge of leak - before the next sample of stimulus.  Call it the task of the clock.

  2 set up a buffered AO task that uses the output of clock as the sample clock. Configure the polarity to be sensitive to the cutting edge (usually, this will be a rising edge).   Start the task AO * before * starting the task of the clock.

  3 configure tasks HERE and CI to use the output of clock as their clocks in the sample.  Configure the polarity to be sensitive at the trailing edge.  Start tasks I and CI * before * starting the task of the clock.

  4. the output pulse should be a task of meter output, configured to generate a single pulse redeclenchables.  Configure it to use the leading edge of the clock as the trigger signal output.  Set the time of 'low' and the 'initial period' to equal precision<1 msec="" delay="" you="" want="" to="" make="" sure="" that="" you="" get="" the="" same="" timing="" on="" every="" trigger.=""  be="" sure="" the="" high="" time="" allows="" the="" full="" pulse="" to="" fit="" within your="" clock="">

  5 examine the "producer-consumer" model so that you can separate your data from your CQI data processing.  You should stream to file continuous rather than it accumulates in large networks.  Write speed of file can be unpredictable, this is why access to the file must be in a separate loop that acts as a data consumer that the loop of CQI data produced.  When you spend real time, assign a lower priority in the process of writing file.

• Deadline for redeclenchables counter finished

  Hello I am new to labview and using a pcie-6323 and had some problems clock. What I'm trying to do is a counter to generate a clock (picture in the figure) and based on it to trigger and generate a different "trigger camera clock' to trigger a camera. Trigger camera clock is a desk finished, redeclenchables. It is a code writtern by former laboratory. Previously it worked very well.

  

  Recently, I would like to add a constant delay for all trigger camera clock pulses, not just the initial one. When I saw this example, https://decibel.ni.com/content/docs/DOC-10685, I tried to add the start.delay to my code, as in the following figure. But once I run the program, I got a 200452 error code and the program must be closed.

  

  I saw this link mentioned to use activate Initial on Retrigger. delay, http://digital.ni.com/public.nsf/allkb/204538A044431C9B86257377004EB952 . But I tried to put it in several different positions, for example after the Creat channel vi, after the moment where vi, after the left trigger vi and the node property trigger, I have always the same error problem.

  I think that the pcie-6323 should be with the STC3 timing engine, http://www.ni.com/pdf/manuals/370784g.pdf , so I don't know why I got the 200452 error. I wonder if there is a simple way to solve this problem and reach my goal. I have seen a few examples used two counters to this late, but I think that there should be an easier way? If anyone can show me a figure or taste vi, it would be very useful. I really appreciate it!

  Thank you very much!

  Startup time is bad, use Initial delay (entrance in create virtual channel - original 0.0008 trigger closed task of the clock). Delay enable initial on retrigger applies to it.

  Another way is to use frame duration clock pulse (duty cycle) as control to delay - start a task on the forehead and the other - on falling edge.

• HSDIO trigger for the transmitted waveform record

  I use a card OR-6552 (actually this system eventually will use 7, so I'll try to get my head wrapped around the trigger events).

  I use dynamic generation to generate a binary pattern on the pins 0-15.

  I'm tracking the trigger from start to RTSI6.

  I use a software trigger.

  On the side of the reading, I use a dynamic Acquisition.  The start trigger is triggered off the coast of RTSI6.

  Everything works exactly as it is supposed to. I get the binary model, BUT

  The read function is advanced clock EXACTLY 50 cycles.  So, I get a '0' reading the lines of channel for 50 cycles before the binary sequence appears in my wave of reading.

  I suspected that it has anything to do with the outbreak of the reference, so I tried to define the source of command reference for RTSI6 also, with delay sample 0, and I get a timeout.

  I'm so close, but I would like to know why I'm getting a pre-roll buffer 50 cycle even if I did not specify...

  CCITest,

  If you are looking to synchronize several 6552 juries, you will want to use TCLK.   NEITHER TCLK is the synchronization scheme products Memory Core (SMC)-based and integrated with National Instruments synchronization.  More information about the details behind this technology can be found in the help HSDIO document (start > programs > National Instruments > NOR-HSDIO > Documentation > NI Digital Waveform Generator-Analyzer Help).  Inside of this help document, a good starting point is the title of programming > references > NOR-TClk synchronization help > preview OR-TClk.

  NOR-TClk will allow you to start several cards at the same time.  Leave your post I don't know if you are using a card PCI-6552 or PXI-6552 module, however when you use a version PCI RTSI cable allows up to 5 tips be connected.  Using PXI, you can fill the frame and synchronize your 7 boards.  There are several examples that show how to use NOR-TClk.  These examples can be found under start > programs > National Instruments > NOR-HSDIO > example.  Then choose your preferred language and select synchronization.llb or the sync folder.

• A measure of speed high speed with encoder in quadrature and NI 9401 on cDaq

  Greetings,

  We use an encoder in quadrature with 360 pulses/turn on the tracks (track A and B) and no trace of Z to measure motor speed at startup. Data acquisition, we use a NI 9401 in 9178 cDaq chassis and a pc with LabVIEW. The problem is that the start-up period is relatively short (less than 1 second), during which we measure speed as precisely as possible. The speed range is from 0 to 10000 RPM.

  What type of measurement method that you would recommend.

  Here are a few methods that we have already tried:

  -Measure with DAQmx CIFreq--> high frequency with 2 counters: speed measurement, but with a very big mistake (+ 166 RPM).

  -CIFreq DAQmx--> wide range with 2 counters: good speed data but more slow measurement,

  -CICntEdges DAQmx (counting separated the two lanes, speed conversion): very incoherent speed data.

  Thanks in advance for your help.

  Matej

  I would definitely say a 4, the measure of a low freq called option with 1 meter.  (Frankly, I've never been

  fond of this name because it is useful for freqs much higher than what I expect most people think "low freq".)   This

  is the method that I almost * always * use for frequency of counter measures.  It works really well to capture transitional

  variations in speed.

  10000 rpm and 360 cycles/rev, you are looking at a maximum frequency of 60 kHz.  The frequency measurement mode 1 meter

  There will be 80 MHz internal clock by encoder cycle edges, then you will get more than 1000 strokes per measure.  The point

  that means only 1 number of quantization errors, you can expect<>

  Further, you can average overall, say, 10 samples to you give even better accuracy and you could still be a data capture

  rate significantly higher than the probable bandwidth of your mechanical system.  (The average would just clean the jitter and noise and would not

  Hide answer true mechanical characteristics).

• The relay through time and Total flow control

  Hi all

  I'm relatively new to Labview and have worked on a great program from lately, which uses a Module with my cDAQ-9178 OR relay SPST 9481 to open and close the 3 different solenoids. The program should open at a specific time and leave it open until a certain amount of flow is passed through them. I already finished the programming to record the total flow through the valves, and after many hours past the forums I found a way and changes in the code that turns on the relay based on the amount of time spent searching, however it turns on the relay and leave them on until the 'period' are filled then pass on the next round. I need to change this option further so that it lights when my "Cycle Start Time" is reached, turns off when reaching the set amount of flow for this cycle and then continues to wait until the next "Cycle Start Time" occurs.

  I imagined a way to proceed would be; by eliminating where departures from the clock a new cycle each run and just have it constantly by comparing the time of "Initial start (run)" 'Start' time sequence (when I push the start sequence and actually start to opening the relay). Then change the "delay" to 'Cycle start time' and the (> =) function to a function (=). So now, it begins after the elapsed time is equal to the start time of Cycle. Certainly, this opens the questions, because currently, at the beginning of the cycle the command of the relay begins. So I need make my comparison outside the case 'Cycle' or move the control relay in the case of 'true/false '. However, then I run the question of how to get the software to change the case once he saw to stop the relay.

  As you can see, I have about 1 million different things in my head that I played with. Advice or assistance to get me on the right track, or you know of examples would be great! My code is attached below, and I'll post a photo after this post about how I'm taking care to record the total flow. Thank you for your time and help!

  Hi M_Blaylock,

  You mentioned that you are relatively new to LabVIEW. Are you familiar with some of the debugging tools?

  http://www.NI.com/getting-started/LabVIEW-Basics/debug

  Turning on climax execution should allow you to see the data flow through your schema. Also, probing the wire just before the input case structure should allow you to see what data is actually trying this case selector. If you get unexpected data, you can probe the front steps to see source these unexpected data.

  I hope this helps and good luck with your code!

• How can I create delays for many digital outputs?

  I use a PXI 6537 DAQ card to produce four digital signals for each starting at a different time. In order to create this delay the appropriate number of '0' have been placed at the front of the boolean table before converting it into a digital signal. It works by creating the delay, however using this process, the delay may be discrete increments equal to 1/╔chantillonnage and my card can be up to 50 MHz, this means that I can produce only delays 20ns increments (check my calculations). For my application, I need to be able to control the time until the second nano. Delays will usually be more than 20 ns, but less than 40ns. I tried to use the entry 'to' the 'build waveform.vi' but it doesn't seem to do anything to manipulate the data. The sub VI used to create the waveform is attached. Sending the data isn't a problem. Thanks in adavnce for any suggestion.

  JS

  Hi JS.

  The 6537 allow placement of subsample edge on its i/o lines.  The best you can do is unique (like you the noticed) examples of resolution (20 ns @ 50 MHz).

  Have you looked at the SMU-6545?  It is a 200 MHz Board, which means that you will get 5 placement ns, as WELL as data delay feature which lets you place your samples with ~ 150ps resolution compared to the output clock.

  Are you having to change the location of a signal in the clock period each cycle?  Or is the position fixed by reference to the clock, but must be placed exactly?

  Thank you
