  1. In case your Electronics Explorer board is not detected by WaveForms application try to do the followings: 1. Check if it is properly supplied with 12V and the Red Power LED is on? The USB controller is powered by this supply, connecting only the USB cable is not suffice. 2. Check if the Yellow USB LED is on when the USB cable is connected? Otherwise, try to use another micro USB cable and computer plug. 3. Remove the board supply, wait a minute then connect it back. Do this, to make sure that all the internal circuits are reset.
  2. Hello, Is there a way to set the voltage level of the digital I/O on the explorer board to 5V? I see the board has a 5V Vcc supply. Is the only possible way to do open-drain? Thanks, Dylan
  3. Hello, My name is Oliver and I am a research assistant at the Technische Universität Ilmenau in Germany. Among other things, I teach fundamentals of power electronics for mechatronics bachelor. Last year I started with a lab course where I use eleven Electronic Explorer Boards. It makes a lot of fun for me and the students. From time to time it comes to an error regarding the scope. After connecting the board, starting the WaveForms application and opening the scope all four channels show -20 V. They stick there regardless what is connected to them. Usually disconnecting the board a
  4. Note To Staff There is no need for help here; I just wanted to share this with others, since it was useful to me. As far as I'm concerned (have power to say?), this code, text, graphics, and attachments are all public domain (preferably with attribution). If there is a specific area or protocol for these sorts of things, I haven't seen it. This post and contents could be stickied, moved, and otherwise used as the powers that be see fit. If there is something wrong, something that needs changed, or something the needs clarified, feel free. /Note To Staff Hello all. I have a small gift for
  5. Hi, I am trying to do some test automation on the electronics explorer board. I have been looking through the Javascript and Python documentation and haven't been able to find a good mapping of values passed to the API's and where they correspond to the on-board resources. Does one exist? I have really been struggling for example trying to enable/change power supplies. Have variable Vp/Vn values and Vcc (on/off/5v/3.3v). Thank you for your time! Dylan
  6. Electronics Explorer Static I/O DIO pins configured as LEDs that are unused/unconnected will light when an adjacent driven LED lights. Details: Board power ON, nothing in the breadboard area, Supplies "Fixed Supply - Vcc" = 5V and "Master Enable" On, Static I/O DIO 31-8 = LEDs, DIO 7-0 = Bit I/O, Switch, Push/Pull. Connecting a wire from DIO 8 to Vcc lights both LED 8 and 9 solidly (DIO 9 has nothing connected to it.) Similarly, connecting Vcc to DIO 9 only results in both LED 9 and 8 on. The same is true for LED pairs 10 and 11, 12 and 13, 14 and 15... The current workaround is to co
  7. Hello all, I am having some trouble with noise from the waveform generator on the electronics explorer board. I have made an op-amp, but the output is very noisy, I thought it was my circuit at first, but it seems the input signal itself is noisy. Noisy in, noisy out. If any of you know of a solution to this problem I would greatly appreciate it. I have attached images of the the oscilloscope readings as well as the inputs I am supplying to the circuit. Thank you for your time, - Micah
  8. Hi. I'm working with the SDK and finally got to the point that I can control the Vcc power supply to be either 3.3 V or 5.0 V. It seems the channel numbers are 0 = Vcc, 1 = VP+, 2 = VP-, 3 = Vref1 and 4 = Vref2. Something like this dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(1), c_int(0), c_double(True)) dwf.FDwfAnalogIOChannelNodeSet(hdwf, 1,1,c_double(1.86)) will work fine and give me 1.86 V or close to it, but if I try to go past about 2 V, it seems like it can't get there and fluctuates a lot. I'm not sure of the difference between AnalogIOChannelNodeStatusInfo and Analog
  9. Hello all, First of all thank you for clicking this post, and please if you are knowledgeable in the network analyzer functions read this if you have time. I am having some trouble with the gain reading of the network analyzer. I am currently a student with a simple project of designing an inverting op-amp with a gain of approximately 32 db (and no this is not me trying to get someone to do my project for me). As far as I can tell the network analyzer must be reading it wrong or I have some setting that is off. I will try to summarize: I designed the circuit by hand, hand calcul
  10. Hi, As seen on the picture I have a problem with the usb connector of the electronics explorer board which keeps breaking. The question is: Can I drill a hole on the red marked circles?
  11. I purchased an Electronics Explorer Board several years ago and used it a hand-full of times and it has since sat in a desk. I've recently been required to use it again for an electronics lab and have discovered it cannot seem to output negative voltages. I have the board plugged into a 12 volt power supply and a usb plugged into a pc. The board's LED lights up and the computer/waveforms recognizes the board correctly. I'm running the current version of waveforms. While running the scope I can measure VP+ correctly with whatever voltages I set. When I atte
  12. Hello, I have a new Electronics Explorer, using WaveForms 2015 software to interface with it. I'm sure I'm doing something wrong, but... * The Vmtr sockets don't read any voltages in he Voltmeter panel of WaveForms * The scope DC pins show their values in both the Voltmeter panel and the scope panel This seems to be contrary to logic, and to the example given in the manual for how to wire up the Vmtr pins as a DMM. Also checked: * Verified with external voltmeter that there is voltage coming out of the VP+, VP- and VCC pins * The AWG works fine It's alm
  13. I purchased the Electronics Explorer a couple months ago and when I tried to use it for the first time last week, I kept getting an error that "There was a power surge on the USB port. Unknown USB device needs more power than the port can supply. " I had the 12 volt power supply plugged in, so I am not sure what I need to do. I did notice that when I first tried to plug the USB plug into the board, it was very difficult to plug in, like something was blocking it. After a second try, it seemed to go in okay, but then I started getting the above error. Please let me know what my opti
  14. Hi, I am wondering if there is any sort of intention to update the electronics explorer? The board looks like it would be perfect for any EE student and hobbyist, but it appears as though the board has not seen any updates in a while (maybe I am wrong?). With the newer FPGAs and parts out there, I am sure you could beef up the sampling rate and bandwidth, and also make for a little higher voltage on the power supply given the space constraints are not as tight as this as they are on the Analog Discovery 2 (which I have an absolutely love!). Does anyone know? Thanks!
  15. My electronics explorer board is not powering up when i connect it to a 12V adapter. I checked the output voltage of the adapter and it is 12.2V when not connected to the board. When I connect it to the board and probe the exposed metal behind the power connector jack, it reads 6V. The potential across the power-on LED is zero volts. I am wondering if there is a fuse on the board that might have tripped due to a current spike or a short? Anyone with a similar experience?
  16. I am trying to use older PAL devices with a Vcc requirement of 5 V on the EE . When using a Switch or Push Button in the Static I/O Module, the output levels are: HIGH: 3.3 V LOW: 1.6 V The low level is obviously too high. Is EE's Static I/O not intended for 5 V?
  17. Hi, I’m using Digilent EEBoard trying to get 1MHz 0V to 4V square waveform from Analog Wavegen. My setting is amplitude 2V & offset 2V but actual output is still -2V to +2V square waveform. Anyone can help? Many thanks.
