  1. Hi,

    I'm trying to use the Analog Discovery 2 to control a stepper motor driver board. All I need to do is send an output (5V) signal using a DIO. I find the Waveforms 2015 manual to be lacking in terms of documentation for this - it does not explain how to give an output signal. How do I do this? Thanks!


    For instance, the reference manual has this sample code:


    function doStaticIO(){

    print("Running StaticIO script");

    StaticIO.Channel0.Mode.text = "IOs";

    for(var c = 0; c < 8; c++) {

    StaticIO.Channel0.DIO[c].Mode.text = "Switch";


    But it is never explained what a Channel is either. What is a Channel and how is it different from DIO1, DIO2, etc.? 

    Thank you so much!



  2. Hi Attila,

    Thanks very much for your response. How do I make an acquisition last for a longer period of time, though? I describe how despite running the oscilloscope for 10 minutes (pressing "run" and then "stop"), I only get 0.1 seconds of data when I save my acquisition. I'm not sure why this is happening.

    Can the scope record data over a longer period of time, like 3 minutes or 10 minutes?

    Thank you!

  3. I'm using the Analog Discovery 2. When I use the oscilloscope, I seem to only be getting a signal snapshot as my output. For example, I ran the oscilloscope for about 1 minute (by hitting "run" and then "stop." I went to the Logging panel and hit "save." I got the attached data as my output. The attached data only spans about 0.1 seconds and also starts at a negative time, even though in my oscilloscope settings I specify that I want time to start at 0 secs. Also, I've tried logging data for different amounts of time (10 seconds, 1 minute, 2 5 minutes) and all the outputs come out to 8192 samples - I would prefer it if I could obtain more samples with an increased length of time sampling. Attached is a screenshot of my oscilloscope settings and logging settings.

    How do I program the oscilloscope so that I can acquire data over a longer period of time?

    Thank you so much!
