FPGA programming depends on the time

• FPGA: unable to update the timer on fpga through host.

  Hi all

  I worked on FPGA project. It has several loops paralel and works with some sampling time.

  I would like to change the "timing" on a single loop, it is called loop output. I would like to slow down the loop so that the loop will update the output less frequently. (see attachment - red circle)

  I modified the code by changing the timer by the host. (see attachment - blue circle).

  I did several things such as:

  1. Add a manual switch that allows me to change the time of sampling mode normal (same time of polling with other loops) in manual mode (set the timer number).

  But it did not work all the time. I checked the value on the host, it is always on the same sampling time, even I write the value of the timer to measure.

  2. I changed the strategy by putting the other control connected directly to the timer (without switch) in the loop so that I can change the value directly. However, there is still no luck. The result is not reliable. It sometimes slows down and many are in the same pace as before.

  3. I even put a case in front of the exit structure so it was only updated after sometimes (all 100 or more loops). It is not always useful. I see the speed varies, but it is not as expected.

  The material is piezo readers/engine. But I want to slow down the speed, does not increase the speed. Thus, it should not be a problem.

  I really appreciate if there are any comments or suggestions.

  Kind regards

  Hi all

  After consulting with my supervisor, he advised me to spend on intermediate or new control value first. Then, update the value of the control that is connected to the timer loop with this intermediate control value. It will update the value of the timer loop after loop (when intermediary value received from the host and update control connected to the timer loop). It works fine now.

  I don't know exactly the mechanism labview of drafting or updating the fpga through host value. But, it seems to me, in my case, there was a problem of writing a value to the control that is connected to the loop timer where ran in relatively fast. Well, little control ignore/reject the new value because it is busy to execute the loop in high speed.

  Thanks again for the response to my post, GerdW.

  Kind regards

• By using the date class to change the alpha of an object depending on the time (GMT)

  Hello

  I'm trying (and evil) to get my head around AS3 and build a flash webpage. I have 2 layers in the timeline, each containing a clip corresponding to the size of the page with instance names backgroundDay and backgroundNight.

  What I'm wanting is for the background to change to the day and night, so that from 18:00 to 06:00 backgroundDay alpha becomes 0 to show backgroundNight behind.

  I've been scouring the internet and haven't found anything, so if anyone can help it would be much appreciated.

  Thank you very much

  Sophie

  Yes, you could use a timer. Something like this:

  var t:Timer = new Timer (1000);
  t.addEventListener (TimerEvent.TIMER, timerHandler);

  t.Start ();
  function timerHandler(event:TimerEvent)
  {
  var d: Date = new Date();
  backgroundDay.alpha = (d.hoursUTC > 5 & d.hoursUTC)< 18)="" 1="" :="">
  }

• Concatenate with DIAdem TDMS files, depending on the time

  This question is in French and English.

  Hello

  I'm trying to find a way to concatenate/merge several files TDMS analog measurements with DIAdem 2012, in order to have more than one file. I be provided with attachment 1.

  I am beginner in DIAdem and don't know not the language of the script code. En 986KO on this forum, I found the script 'Import data from several Files.VBS use', and changed lines 17 and 18 not 'csv' by replacing "tdms" (as it was stated on another topic on the forum). This script also appealed to "concatenate groups."

  The problem is that the TDMS files contain several groups (the slots on frame of measures Canada) each containing several different channels. This script concatenates so each group and the result makes more sense the script to modifier is certainly "CONCATENATE Groups", but in what way?

  Thank you

  Olivier

  I'm trying to find a way to concatenate/merge several files TDMS analog measurements with DIAdem 2012, in order to have at the end only one file. You can find these files with my mail 1.

  I am a beginner in tiara and do not know the language of the script code.

  By searching on this forum, I found the script 'Import data from several Files.VBS use' and changed lines 17 and 18, replacing 'csv' by "tdms" (as demonstrated in another topic on the forum). This script also uses "groups of concatenate.
  The problem is that the TDMS files contain several groups (pointing to the slots on the frame measurements), each containing several different channels. If this script concatenates each group and the result is meaningless. I think the script that needs to be changed is "CONCATENATE Groups", but how?

  Thank you

  Olivier

  Hi Oliver,.

  Try to run the script you downloaded once for each group and encodinng group to load in the assignment of "ChannelSet" in line 10 using the index group, like this:

  ChannelSet = "[1] / *" or ChannelSet = "[2] / *".

  I just found out that this example breaks in 2014 DIAdem because the 'DataFileHeaderAccess' command has been relegated and replaced by a new.  I need update soon.

  I recommend you to go through the basic materials of LabVIEW which will give you an understanding on the basics of bases/components of LabVIEW.

• Program LabVIEW will hang between 33% and 50% of the time.

  I have a problem with a Labview program, I did. I have two programs that do the same thing. One is as a flat sequence, and the other is in the form of State machine.

  As explained in the link below, I would like to use a microcontroller to perform wiring for automation of a measurement process. A separate current source and volt meter will be used.

  https://forums.NI.com/T5/LabVIEW/sequence-a-good-idea/TD-p/2601333

  I did some simple test programs that I join since then. The problem is when running, that the labview program crashes, but not all the time is to run the program.

  For example: Hall 1.2.vi will correctly work twice with the third time, he is executed, it crashes. If Cancel you and try again, it will run again twice without any problem with the third hanging. It is in the flat sequence format (was in a flat sequence, but merged windows because I thought that was the cause). From what I can tell, the program crashes when calling Keithley 6517 unique Read.vi. Two connected Keithley devices are connected to the computer via GPIB to 16 and 27. The way I checked if it was this vi the cause or contributed to what I deleted the program never hung and it. I find it very strange that it crashes exactly on the third attempt every time.

  Simple.VI Hall 1.3 will work the first time and hang the second time. If it works 50% of the time. It is in the format of State Machine. It hangs in the case entitled "Measurement 1" that contains the Keithley 6517 unique Read.vi.

  I used the running highlight button and watched the program to run. Curiously, it only crashes when you use this button. So I tried to add some delays/waiting in different places without success.

  This could be the cause? As a side note, I say that the program is suspended for two reasons. The principal is the program does not run so the execution arrow is always black. The second thing is that if you notice at the end of the labview program, I have a block he who turns to the power source which does not happen when it crashes. I have to turn it off manually, and then click the abort program button to stop labview.

  Hello jerrylumpe

  1. If you use an old mouse, try to clean it.

  2. you can have a running process in the background that keeps XP thinking that he is busy and so the screen standby does not start.
  Go to msconfig and uncheck everything you don't need, then see if the screensaver will kick in.

  Start/run and type
  Msconfig
  Ok

  Startup tab
  Keep the page open then click on the link below. It will tell you what are all the entries and see if you can disable them or not

  http://www.SysInfo.org/STARTUPINFO.html

  Read the key at the foot of the page, then click on "Here" at the top. Use the search box to check all your entries

  Try this too
  http://www.kellys-Korner-XP.com/xp_tweaks.htm

  Line 51 left side. Click on "toggle".

  It could be that something is resetting the timer. For example, it does take much vibration to move the mouse a little, and which will reset the timer to zero. Something like that would be possible? Or a pet that walks on the keyboard?
