I changed my VI and inserted a MSO Query Acquisition Status between the MSO Run and the MSO Read. I also put an event structure and a loop to check for Stop button in the same loop. This allows me to hold off on trying to read the data from the instrument until acquisition is complete and check for stop button event. I still can't stop the execution with the Stop button on my front panel. I'm just trying to emulate the functionality of the Stop button in the WaveForms app, in which, regardless of the status of the MSO, you can hit stop and halt execution. This should be simple to emulate with the Digilent WaveForms VI's.

I'm wondering if the DWF MSO Stop.vi function would be able to stop or interrupt the DWF MSO Read.vi function if I invoke it using the same instrument handle from a structure running in parallel. Would it have equal or greater priority? I'll wait for @attila's input. Thanks

Hi JColvin, Yes the DWF MSO Stop.vi is available but I am wondering how to use it once the DWF MSO Read.vi has been called. It seems like once once we are inside DWF MSO Read.vi there's no way to abort or return unless all data has been read from the device data buffer. I'm hoping there's a simple solution that someone can suggest. Thanks!

Hi JColvin, After I hit the Start Button, the execution starts fine and the AD2 waits for the trigger condition. I turned on "Highlight Execution" I noticed that execution is stopped inside the DWF MSO Read vi (see image attached) which is expected since the trigger has not arrived yet. However, I want to be able to interrupt it when I hit the STOP button but it seems like no other event has the ability to interrupt the DWF MSO Read vi (other than unplugging the AD2). Any suggestions?

Hello, I created a sub VI which contains a simple analog channel acquisition flow using the the AD2. I wanted to use a START and a STOP button to control its operation. However, once I hit the START button, the VI hangs and won't respond to any front panel action until I unplug the AD2 device. It's probably something fundamentally wrong with the way I am implementing it. Any help would be greatly appreciated. Thanks Scope Hang Debug.vi AD (SubVI).vi

Hello, I just wondering if the cross triggering capabilities described in the tutorial below can be accomplished in LabView Digilent WaveForms VI library. https://reference.digilentinc.com/learn/instrumentation/tutorials/analog-discovery-studio-using-cross-triggers Does anyone have some example VI's that demonstrate cross-triggering? Thanks!

HI Atilla, I've been using the AD Toolkit with LabView but have not found the Math Channels feature that WaveForms offers. Do you know how to add a Math Channel? Thanks!

Are Analog Discovery Math Channels available in Labview? They are described in the Digilent WaveForms app documentation as follows:

Thanks attila! I'll give it a try! I'm assuming this can also be done using LabView?

Greetings! Is it possible to start sampling the scope channels based on the state of one of the digital I/O input? Suppose I have a CMOS digital input pulse that starts at logic 0 and goes logic 1 fafterr 100 us. I would like to sample Oscilloscope input channel 1 and/or 2 for the duration of the digital input being high. Thanks.

I am using the Analog Discovery 2 with Labview 2018. Is it possible to start sampling the scope channels based on the state of one of the digital I/O input? Suppose I have a CMOS digital input pulse that starts at logic 0 and goes logic 1 for 100 us. I would like to sample Oscilloscope input channel 1 and/or 2 for the duration of the digital input being high. Can someone provide me an example on how to achieve this? Thanks!

Hello, I tired using the Write Delimited Spreadsheet vi to save the analog waveform from my AD2 to a CSV file. However the content of the file that is generated only contains a single data point instead of the entire waveform. I am suspecting I don't have the data connection wired correctly. What is the proper way to connect the Analog Waveforms output of the DWF MSO Read (VI) to the Data input of the Write Delimited Spreadsheet VI Thanks!

OK, I tried it last night. Works fine!

Will the Analog Discovery work with a MacBook Pro Thunderbolt 3 (USB-C) ports?

Thanks!
