  1. Hi I've been using the AD1 for about a year. But now it seems the second scope doesn't function properly. When i run the scope on WaveForms it stays at -29V. Does anyone know if it's an SMD or something i can fix myself? Thanks
  2. Hello, I am working on a project that involves using the digilent analog discovery 2 to act as a an input and output for a VI in LabVIEW. I have downloaded the Adept and Waveforms software to communicate with the discovery 2 and LabVIEW. In this VI, I am getting an error number 1097, which has to do with the call library function. The error is in an attached photo. I have tried the suggested fixes online but have not found one to work for me. The error does seem to occur at the sub-VIs I downloaded from National Instruments, built to work for the discovery 2 in LabVIEW. When I open the ca
  3. Hello, I'am writting my own software to setup an Analog Discovery 2 device and conduct some mesurements in C# using SDK library and wraper. I can connect with the device, disconnect and even retrieve some information such as serial no. I would like to have some sort of protection in case if device is rapidly unplugged from computer. In this particular circumstances in Waveforms software an error will occur. I have tried some sort of checking with use of enumerators but enumerators works poperly when device is connected. When device is disconnected last status is remaining a
  4. Hello, I have an Analog Discovery (legacy) and the latest Waveforms app. I am trying to write a script that makes the protocol module write to a 24C16 eeprom, read it back, and print to the screen or window. I can access th I2C (can see on my scope), but I can't print anything. The print() function does nothing unless in debug mode, but then the app seems to hang. I tried Custom mode and Sensor mode. And I tried the ADXL345 example, with a known good breakout board, and it always returns the same thing, doesn't change with orientation of the chip (but my main concern is the eepr
  5. Hello I am a user of Analog Discovery2 and I believe it is missing one very important (for me at leas) function. I basically want to monitor and register the communication between two devices which use UART to do so. The Protocol panel looks great but I am able to register only one of the devices at the same time. Logic panel is very unfeasible in my case because I want to register many lines of the communication (like 5 min). Is there any way I can achieve that? Maybe there is a custom script which would help in my case?
  6. Hi Folks Although the Analog Discovery has fully differential analog (scope) inputs, the Discovery BNC adapter board does NOT! For some reason the negative inputs of both analog channels have been connected to the Analog Discovery ground. Therefore, they form a short circuit between any conductors they are connected to. Why is this important? I just found out the hard way, when I connected the scope leads from the Discovery BNC adapter board to parts of a circuit at very different voltages. I was expecting each channel to measure the differential voltage across each probe. Instead, there w
  7. Hello all. New to WaveForms, so excuse me if this is too easy. I'd like to capture an analog channel, and two digital ones - where information is encoded into the width of the pulses. Sure enough, I can do this. But of the digital, one is PWM, which I'd like to manipulate into the corresponding stream of percentages (or 8-bit values, does not matter); the other one encodes the duration of something - therefore I'd like to measure their positive duration, as in a timer/counter... Can this be done in WaveForms with the AD2?
  8. Hi, so I am trying to complete a project for one of my classes and I decided to us the script part of the analog discovery; however, there is not enough comments on the code to explain what it is specifically doing. I found an example code that is titled "Wavegenpiano". I would like to know if someone can explain what that code is doing., ie, what each part of the code is doing. I would like to use that code associated with a buzzer to output a song. TL;DR How can I use the script part of the analog discovery to have a buzzer output out a sound?

  10. I'm trying to take accurate readings using the "Logger" module in Waveforms 2015. When I power up a simple DC circuit with +5V, and use a DMM I get readings of ~4.44 volts. However when I run the data logger module, all of the readings are <100 mV. Shouldn't the logger be reading ~4.44 volts, or is there some configuration I am missing Thanks in advance!
  11. Hello, I'm a newbie using the Analog Discovery (Legacy), and attempting to run through a few experiments. When using the Power Source or "Supplies" tool in Waveforms 2015, all the directions and manuals show a dropdown menu where you can adjust the voltage (0-5V). The manual from Digilent's own website SPECIFICALLY regarding the Analog Discovery Legacy shows this as an option as well. I can't find any such option however in my program, it just isn't there. I should mention that I am powering the AD itself via USB from my laptop, but I don't think that is the issue as according to the

  13. Can the Digital Discovery logic analyzer be configured for state analysis? Specifically, can you designate one of the IO's as an input clock source and choose the appropriate edge for capturing data?
  14. Hello, I have an Analog Discovery and I recently installed WaveForms version 3.3.5 (I actually found it a bit ambiguous how to install WaveForms. I attached an image below of the files I downloaded from Digilent. All I did was click and drag the framework into the corresponding directory and likewise for the application. Then I ran the driver installer). I am running Mac OS X El Capitan 10.11.5 on my Mac laptop. When I look under the USB device tree in System Information I can see "Digilent USB Device" but when I open up WaveForms it alerts "No device detected". Would anyone kno

  17. Hi Folks I'm using an Analog Discovery. For my current project I need to isolate it, but it doesn't work when I try to connect it with a USB isolator. According to the manual... I've tried USB isolators from 2 different manufacturers. The Analog Discovery doesn't work with either of them. When the device connects I get an error message during device configuration (image attached). Is it possible that the software has changed so that it now doesn't work correctly with a USB isolator? It may be a timing issue during configuration, since the isolator only runs at 12Mbps. If so, is it possibl
