• 555 timer

  Hello

  Ive had some issues with the 555 timer. I'm trying to get a signal of pulswidth set to a current signal.

  My problem is that the circuit should work with 0.25 to 1 Hz on the current signal.  I clocked it at 1 Hz, but if I try to go further down the timer begins to go crazy.

  im a noob really into stuff like this and happy with every little help

  I hope someone can help me

  Thank you

• Amnesty International and counter sync + USB signal stream (USB-6210 vs USB-6341)

  Hi all

  I'm at a stage of identification of a material suitable for the following tasks:

  • 5 analog inputs (AIs) of reading at the same time, tensions at a rate of kSps (at least) 10,
  • application captures 2 inputs using timers (detection of contours with timestamps), square wave entry with duty ratio of 50 percent and about 1.5 kHz frequency and variable pulse width / frequency (from 2 sensors hall, representative of the DC motor rotation speed and direction, quadrature signals), resolution of timestamps should be (at least) 50 ns,
  • AIs and counters should behave in a deterministic way, and must be synchronized in a way,
  • data to be transferred via the USB port of a host computer with Matlab Data Acquisition Toolbox (unfortunately not LabVIEW).

  I've identified the long USB-6210 USB-6341 and potential candidates of material to accomplish the above tasks, but after reviewing several documentation and the topics of the forum, I'm still a bit confused, if both are fully working and my approach described below is not working properly.

  Counters: I intend to use the internal time base available 20 MHz as being the source of meter to get into account the resolution of timestamp 50 ns. External impulses hall are used as sample clock (about 1.5 kHz, see above). As the pulse width varies, the sample clock is not constant.

  AIs: Using a 10 kHz internal clock signal derived from the time base of 20 MHz for timing and analog inputs (trigger) start-up and counters simultaneously material should translate into the required synchronization and deterministic behavior.

  It work? Other recommendations?

  Next is the USB data transfer: all HAVE 5 and 2 data entry of the meter must be correctly transferred to the host computer (the corresponding rates are shown above). USB-6210 is capable of 4 USB signal flow, device USB X range (6341) offers 8 of them. Unfortunately, I could not understand the exact meaning of the expression "signal flow" still. Do I need 1 flow of input signals (would be 7 for my application described) or 1 stream for all analog inputs and 1 for counter inputs (lead 2 streams for my request). Is there no further details on this approach (more than Streaming of signals of NOR) USB signal flow?

  Any challenge to the described application that I might have forgotten? 6210 USB seems to a very limited number of entry PFI, maybe even too low for my meter participate application?

  Looking forward to your comments and advice.

  jAwA

  1. I recommend the X-6341 series on the M-series 6210 sake of counters/timers.  It is more of them, and each of them is more capable.   It can also have a great FIFO embarked for meters that may be important in certain tasks, although I don't think that you currently deal with one of them.

  2. your general concepts on timing & sync are satisfactory.  You will be able to share and to route signals that help ensure synchronization and determinism between the timestamps for your various tasks.  Note that for meter entry tasks, you need set up the trigger 'Arm Start' rather than the regular start trigger.

  3 is not authoritarian, but I believe that the flow of signal # will correspond to the tasks #.  For you, it would be 1 task of HAVE and tasks CI 1 or 2.  (Not clear if you have 1 Encoder with 2-channel quad that would require 1 task of CI, or if you have 2 encoders with 4-way quad).

  4. pay attention to the hall effect signals that are not virgins.  Digital filtering is available and probably better on the X-series, the series M.

  5. strictly speaking, edge detection is a type of digital input task that produces samples but no timestamps.  Ideally, I would like to parallel wires on the two digital inputs for the entries of detection and counter change to position quadrature decoding.   Then I would sample the counters Encoder 1 or 2 using the internal pulse 'event of detection of change '.  I would create another counter timestamp change detects pulses as well.

• Waveshaping circuit using a 555 timer

  I tried to reproduce this circuit much longer. I am trying to use a timer 555 as an Astable multivibrator with a suddenly IC monostable circuit.  However, when I create the circuit and use different combinations of RC I actually get a correct output of the timer, but it does not cause the one-shot get active then and I can immediately connect a clock of multisim that turned the circuit works very well.  Can someone please take a look on the circuit, I have designed and see where I was wrong? Refer to the multisim file attached.

  Ohm's law,

  Sorry for the delay on this point - we have been busy in the ISF group.

  Your tour was very close!   I think that by not only not the CLR and a cable entries, your circuit had problems.   Probably the pins of the CLR was defaulting to a low logic (requiring so low Q and Q ~ high) as indicated in the data sheet.

  Here is the circuit has been corrected (note I increased the capacitor to give lasting impulse on Q / Q ~ because the pulse of the 555 timer period was approximately 250 ms).

  In dealing with digital circuits, it is often convenient connect digital inputs to an interactive SPDT switch and VCC (or any level of CMOS circuit is in) and ground as I did here.   This gives you the ability to interactively control parts of the interactive test circuit...

• Log down the accumulated power on/off time and the number of cycles

  Hello

  I use LabVIEW to build a test program to monitor the status of the 9 switches for a long period of time, and I need to connect the following data:

  How many times the switch turned on?

  How long has the switch turned on?

  How long the switch is off?

  I built a VI, but it seems really huge... So, how I can simplify it?

  Also is there any method to reduce the consumption of CPU resources? For example using the function 'to wait '?

  The data stored in the table are in this format:

  	Cycles counter	In time	Out of time	Buffer
  Switch 1
  Switch 2
  ...
  Dip-Switch 9

  Thank you

  David

  Your method would require repeating the log F-> T and T-> F routines in each case for ever value, structure, which can be a pain if you need to make a change to this routine.  Review the code that I joined.  The deal structure that I will contain an instance of every routine and the line of the 2D array that it applies to is dynamic and determined by which switch has been switched.  In addition, you can just the array of Boolean to the tip of needle of the index and read its value.  If set to True, then this was a F-> T transition, and so wrong it is a T-> transition F.  Another thing, you had connected the stop button to a terminal of the while loop stop.  When you have a structure of the event he's right there waiting for one, it's events to trigger it in action.  There was no event stop Stop button never actually stopped the VI.  So I added back a change of value of Stop event if it would work.  Let me know if that makes sense.

• Problem with timer and Reset. Help please :(

  Hello everyone, I have a big problem when I put a button to reset my program. In addition, from the time of my game.

  I am doing a project named "Simonsays" which consists of a sequence of colors that you need to remember and must click on each color to pass the level.

  The problem is that I do a clock or a counter to count the time of a game. For example when I press "start" the beginning of time, and when I make a mistake in the game time must stop. There is another button named "New Game" or "Nuevo Juego" which is used to 'RESET' of the game, but I can't this is the button used to RESET.

  The game starts when you press "COMENZAR" and labview window disappears, then you will need to click on "START" and the game begins... BUT when you make a mistake, the game must be stopped with the TIME that you make throughout the game, and the game must wait until you press "NEW GAME" and newly him game begins with a new counter of the time.

  I hope you can help me. Please, I beg you.

  There are 3 files, because the files are connected.

  Thank you.

• Problem about the listener, the timer and the timer task

  Hi all

  I create an application that is listening to the incoming call.

  When incoming call arrives that a single clock time is beginning for 1 min.

  If an another incoming call arrives less than 1 min this timer must be handed over to zero and count from the beginning.

  but in my case it not to reset the counter, will launch the counter where it was finally.

  both my variable are static

  any help...

  And what is the status of idel of application if the incoming call is coming.

  application is paused or in working order?

  I suspect that you have other problems, but before we start looking at these, please can you change your "static" variables and use RuntimeStore for these.  static variables are not singletons, except in certain specific circumstances.

  http://supportforums.BlackBerry.com/T5/Java-development/create-a-singleton-using-the-RuntimeStore/TA...

  Another recommendation.  Do as little processing as you can in a listener.  Swap in your own application to perform any significant processing.  Use GlobalEvents to swap in your own application.  Here's the good KB article that will help you to do so.

• Questions AS3 Timer and navigation

  I'm working on a project with AS3. On the timeline, I have a clip that contains a timer (single frame). The timer for testing purposes was put at six seconds. In the timeline are two labels (page1 and page2). Timer is on page 1.

  PROBLEM:

  I would like timer passage on page 2 on scene1 when time is zero (0). Please suggest how to do this.

  Here is my script:

  var myTimer:Timer = new Timer (1000, count);

  myTimer.addEventListener (TimerEvent.TIMER, timeRunning);

  myTimer.start ();

• Delete one sentence at a time and keep the rest

  Hi all
  
  I wonder how can I do this in the jargon
  
  I have an XML file that contains 4 sentences. I load these phrases in Director and I would like to allow my users to delete words from the NCB at a time and keep the rest. For example
  
  Phrase1
  Statement2
  Phrase3
  Phrase4
  
  If the user selects a 2,3,4 must remain in the display area. If 2, 1,3,4 must remain in the area of the display and so on. The process must continue until there is only one sentence in the window (one of the 4) where the user must open a window of message (game over).
  
  Do you have any idea how to do that?
  

  This behavior removes a line when clicked and displays the
  message when there is a single line on the left. You can easily modify it to display
  the message when there are 2 lines to the left, 3, or whatever. It also records the
  complete original list and restores the Member on sprite end.

  Of course, you have to fix induced unintentional line breaks

• Worn and counting on the same query?

  I have a table with the following fields: groupname, FULL_NAME, DEFAULT_X, SUPPORT_GROUP_ID and PERSON_ID (among others)
  A user (PERSON_ID) can be different times, they appear once for each group (SUPPORT_GROUP_ID) that they are assigned to.
  When the DEFAULT_X == 0, this means that the user's default group is on this line. Each user should have only one only by default the group, but for some reason, the table was corrupted and there are a few users that don't have a default group.
  What I'm trying to do is to select all the users (FULL_NAME, PERSON_ID) where the PERSON_ID COUNTY is equal to the SUM of DEFAULT_X
  It sounds easy enough, but I don't even know where to start.
  Any suggestions?

  Hello

  So you say
  default_x = 0 if this is the default group, and
  default_x = 1 in all other cases
  Is this fair?

  If so, you can say:

  SELECT    person_id
  FROM      table_x
  GROUP BY  person_id
  HAVING    COUNT (*) = SUM (default_x);
  

  HAVING is similar to WHERE, except that HAVING is applied after the merger took place and functions of aggregation (like SUM and COUNT) were calculated.

  However, your problem is that default_x is not entered correctly. If default_x is sometimes 1 to 0, are not concerned it may contain other errors, like having 2 or - 1, whereas she would have to have 1?

  Here's a better way to find person_id who don't exactly have a single line with default_x = 0:

  SELECT    person_id
  FROM      table_x
  GROUP BY  person_id
  HAVING    SUM
            (
                CASE
                    WHEN  default_x = 0
                    THEN  1
                    ELSE  0
                END
            ) != 1;
