How to run 4 LED in a circle

Hello guys,.

I have a situation that uses a clock (called every 5 seconds).  When a timer is called, there are 4 LEDS which are in action. I have travel blick in a circluar for the next 5 seconds, and then the control is passed to another series of LED that performs the same operation.

My question is, how can make a set of 4 leds blink and close way circluar (ONE IE 1, 2-ON-1 FARM, 3-ON-2 OFF, 4-on-3, Ontario - 4 OFF 1 OFF and so on). in such a way that they are visible to the user.

Thanks and greetings

Roussel

This looks like a good application for arrays of LED control; You can find an example distributed with CVI, called ledctrlarray, or examples of application here or here

Your existing timer would trigger, which is to launch a second "clock LED" operating at 5 / 4 = 1.25 s (or faster), so that each 1.25 s a LED is on and the last LED is off. You will also need a counter so that after one (or more) full circles the second timer and so the flashing is off again

    I have an executable file coded in python. I can run this program on linux but not on Mac.

    Do you have any idea how to run it please?

    Thank you.

    Python is available in the Terminal, which provides a unix command-line environment.

    Some python applications may need to be recompiled to run on Mac. You should maybe download and install Xcode Tools to get full access to all the compilers and related tools.

    Hi!, Ahkran:

    Happy new year and welcome to the Forum!

    (1) you need to download the library library 764, BESSEL V1.2, HP50G, in the HOME directory.

    Now, you need to install and stay permanently in memory, in any port (0, 1 or 2). Best if the option port 2 (Flash)...

    Now, reset the HP50G, with YOU and key F3 (C)...

    Find the library in Port 2, with orange right shift key and key LIB (2), with name BESSE. If necessary, use the NXT (L) key...

    Now press the function key (F1... F6), just below the word BESSE, in your HP50G.

    You have to see...

    and with NXT - key...

    Carefully read the instructions for use library 764, the .pdf file, the author.

  • Lean how to run the stop code when the highest level VI ends

    Hi people.

    I am a newbie of LV with 30 years of experience in embedded SW engineering.  I searched for how to run the stop code when a VI of highest level ends.  I found many examples, but they are horribly complicated.  A little birdie told me that such a model of simple design should not be so compilicated.

    My application is an application of high tension control to disable all HV checkpoints when the SW ends.  My VI code is running in a while loop with a stop button that leads out of the loop.  I can easily accomplish my requirement by programming with a sequence of plate that runs after the end of the main loop.  The technique of flat sequence does not work when the user clicks the Cancel button in the toolbar of façade, more than that market when the user clicks the close button of the application (X button) when you run the exe application.

    Can someone tell me please a simple technique, the code example that can show me a lean and elegant way to accomplish my task?  It doesn't have to be an obvious solution (for example a stop induced watchdog seems simple enough).

    Thank you - John Speth

  • How to run XsdObjectGen in Visual Studio 2010?

    If Visual Studio 2010 does not support this tool, what is the replacement tool? But the generated XML classes must be the same, because we have other classes and third party requests for reference for the classes and the XML files generated by XsdObjectGen in 2005 VS.
