  1. Hello! I'm not trying to be an internet troll and perhaps I'm misunderstanding what you mean by satellite, but I suspect most of them are some expensive military grade processor that isn't very user friendly. This website seems to list some processors that have been used but it hasn't been updated in nearly 6 years... On the other hand though, what exactly does a satellite have to do with Digilent products considering this is on a Digilent forum instead of something like stackexchange or reddit? ~Natsu
  2. Hello! I'm by no means an expert or anything like that on oscilloscopes or software or drivers or anything like that, but it seems like there are a lot more threads on the WaveForms software than just this thread that seem to have been resolved successfully... and if you've given up and have no interest in seeing if anything has changed, why are you still here? Mostly I'm just a curious passerby. ~Natsu
  3. Hello, I don't have any technical advice to offer, but to a certain extent this conversation all seems like a problem with the Xilinx software experience since I don't think it's on Digilent to provide methods on what appears to be (from my inexperienced viewpoint) a non-standard use case. Or at least I presume Digilent isn't obligated to support non-GUI usage of Vivado. On another random side note, it may sometimes be a bit for Digilent to get responses from co-workers since there doesn't seem to be that many Digilent support people available to begin with, especially if it happens to be
  4. Hello! I don't know much about PWM or PDM, so maybe I've misinterpreted everything but I was under the impression that the blog post wasn't intended to be the ultimate solution for everything. I don't disagree that engineering should be replicated by other people to help ensure it all works rather than accepting stuff blindly, especially if it's vital for a projects success, but it looked like [email protected] was looking for better audio quality rather than launching rockets... On a different note, it looks like from his main blog page that [email protected] was at some conference these past few days so mayb
  5. Hello! I don't know the answer to your question at all, but if it's an option to you, it seems like a microcontroller based solution will be a lot easier to work with in terms of bit-banging SPI rather than working with Xilinx SDK which inherently has to use high level abstractions to control and rewrite the FPGA fabric to have it perform as you want it to. I'm guessing Digilent didn't create the SPI IP or the Microblaze, so I'm not sure anybody here on the forum could give you the internal details on how the IP works at a low level or what specific commands it uses; you'd probably have t
  6. Hi! I don't have much in the way of useful advice to offer, but I'm thinking that the SEL pin can probably be left floating since it has a pull-up resistor to Vcc on it, at least according its schematic, so the IC5 is using that 20 Ohm resistor in what kinda looks like a differential amplifier in that lower right hand corner of the schematic. Setting SEL to ground would switch it so that the IC5 is using the 100 kOhm resistor, at least as far as I can tell. -Natsu
  7. Gotcha, that makes sense. I hadn't considered the fact that you would need hardware at least twice as fast as the signal of interest to nicely analyze it. I can still dream about it though at least. -Natsu
  8. @attila, Could the USB protocol become supported? I don't have a particular application in mind that I would use it for, and I imagine that it would be tricky to show nicely since I think USB tends to have some overhead in the datastream, but I think it would be super cool to tout that WaveForms 2015 can analyze USB -Natsu
  9. Hi Jon, I obviously haven't been back on here for awhile, but I did finally get that code working (after months of not looking at it). The problem I ended up having was I was having the LED output be based on the current LED state rather than the current switch state...XD. Since this nicely creates a recursive function (did I mention recursion?) or combinatorial loop in FPGA land, Vivado nicely decided to avoid letting me do that. Of course, the learn module based the outputs (leds) on the inputs (switches) and did not run into this problem...evidently I didn't actually read through examp
  10. Hi PaulStoffregen, I tried out your library from your github and didn't get any of the compilation errors you were mentioning. I wasn't sure how to specify path file within the .ino to make sure it linked to your library rather than the defaults, so I ended up deleting the Ethernet library folders from both the chipKIT core library set in AppData and the Arduino Ethernet library folder from the Program Files on my Windows 10 machine (since I figured I could always uninstall and re-download if something went drastically wrong). I am using the Arduino 1.6.13 ide and the chipKIT boards 1.3.1
  11. Hi! I've been working on learning how to use FPGAs on my own and was feeling pretty good after finding a nice getting started guide for Vivado and some introductory projects using Verilog and successfully getting those projects to work on the Arty and even using some external IO with the Pmod ports since the Arty doesn't have all of the embedded switches and what not that some of the other Digilent boards seem to have. I'm using Vivado 2015.3 with the WebPack edition (maybe the Design Edition, I don't know if my voucher ran out yet or not). But my question is on the project 5 in the
