  1. Thank you for replying. I was able to get around this issue by using the Digilent Waveform vi's. I suspect that the AD2 toolkit is not supported by Labview 2017.
  2. Hello, I've constructed a VI that captures analog data from two channels on the AD2. I can successfully collect data, but for some reason, if the number of samples exceeds the sample rate, the data is truncated to only 1 second of data. This occurs for various sample rates (10 samples @ 1 Hz or 10,000 samples @ 1000 Hz, etc) - see attached for more details. I've timed the execution of the "Analog Read" function, and it executes in multiples of 1 second (i.e. 250 samples and 300 samples at 100 hz, both execute in 3 seconds), but I only get one second of data. Questions: Shouldn't this function be able to provide the complete set of data, as long as buffers aren't overrun? I don't see any terminals on the sub-VI's that allow the data buffers to be altered. Is there a way to modify the sub-VI to provide a complete set of data? Any help is appreciated Timing Issue.pdf AD2 - Multiple

    AD2 Toolkit Errors

    Update Feb-16-2019 So I read thru some older posts about the AD2 toolkit, and discovered this post, which was never resolved: As noted in that post, and verified by me, the AD2 toolkit VI's will not work unless a Waveform VI is opened first, and then the AD2 VI. I was able to run the example VI's, but Labview did issue a warning as shown in the "error 3" image. It seems that I've found a work-around but not a solution. -------------------------------------------------------------------------------------------------- Hello All, I will be using the Analog Discovery 2 (AD2) device for several DAQ projects in my measurement and instrumentation class. Unfortunately, I am struggling to resolve numerous errors when I attempt execute example VI's from the AD2 Toolkit. Regardless of the example, Labview outputs errors essentially from all the VI's failing to execute (see images), and that the function nodes cannot be executed because the library is not found, yet all of the functions are in the installation directory (C:\Program Files\National Instruments\LabVIEW 2017\vi.lib\Digilent\AD2 Toolkit). I installed the AD2 Toolkit Using VI Package Manager. I've uninstalled and re-installed the toolkit with the same results, and followed the setup instructions: What's strange it that I can interface my AD2 with Labview using the Digilent Waveform Tookit without any issues. Here is my Setup: Windows 7 Professional 64 Bit Labview 2017 Verson 17.0, 64 Bit Home / Student Edition Waveforms Version 3.9.1, 64 Bit Qt5.6.3 Windows 7 Digilent Waveforms VI's v1.0.3.26 AD2 Toolkit v1.0.0.3 Analog Discovery 2 (non NI version) I will need to use the AD2 toolkit for my coursework and am not sure what the issue is. Any help is appreciated.
