  1. It's working! I ran as admin, no dice. I checked in Control Panel -> Programs and Features -> Turn Windows features on or off, and it looks like Hyper-V was never enabled. (Relevant forum post here at the end of this one.) Finally, I increased the WaveFormsLive HTTP timeout from 5 seconds to 10 and that seems to have fixed it! Thank you for your help James!
  2. Brief update: After a bit more digging, I think I've determined that the drivers are up to date. Unless I'm mistaken, there would be a visible warning next to my device in the Device Manager, which there is not. Just to be sure, I attempted to force an update to the drivers (right click->Update Drivers), having Windows search for drivers online. This resulted in the attached reply stating that my drivers are up to date. Additionally, right click->Properties->Driver states that I have FTDI version So that seems like a dead-end. Any other ideas?
  3. Hello James! I've recently purchased an OpenScope for work, and I'm having the same problems here. I'm running Windows 10, and I've tried this in Chrome, Firefox, and Explorer to no avail. Last night, I was able to connect very briefly, but unable to connect to the COM port. I was a little worried about hardware as I never got any blinking blue lights, but that later turned out not to be the issue. This morning, I tried again on my Macbook, and not only successfully connected, but also updated firmware and calibrated. I tried again on my Windows 10 machine, and even though I'm n
  4. I've just finished reinstalling the WF32 bootloader onto two of my WF32s, and I'm still getting the "Unable to signon, this does not look like a bootloader" error. I downloaded the bootloader from here: https://reference.digilentinc.com/reference/microprocessor/wf32/start I used chipKIT programmer, and programmed using the MPLAB IPE. The IPE claims that the bootloader was verified, so I'm wondering if there's maybe a problem with the bootloader I'm using. Either that or maybe the FTDI is busted? EDIT: I've figured out the problem and of course it was something stupid. While
  5. That sounds about right. I thought that I'd checked all my WF32s to make sure they had the correct boot-loader, but I just tried a uC32 and a Cerebot MX3cK and those worked fine. It's probably the boot-loader then. Thanks! I'll look into how to fix that.
  6. That's great to hear! I've installed it, but unfortunately I'm still getting errors. On Arduino 1.8.5 and 1.6.13, the code compiles, but does not seem to be able to upload. On Arduino 1.6.9 (recommended) I get a compiler error. I've copied the error message for both below. Additionally, the board's port is reliably detected when it is plugged into the computer before I start up Arduino. If I plug the board in after Arduino has started, it is not detected at all.(Arduino 1.8.5 and 1.6.13, verbose) (Arduino 1.6.9, verbose)
  7. I'm having the same problem. Most of the time, Arduino can't even detect my microcontroller's port. When it does, I get the "No Target Found" error (pic attached). I'm on Arduino 1.8.5. I've also tried 1.6.9 (which I believe is the recommended version) and 1.6.13 (which has worked for me well enough). chipKit core 2.0.3. I'm on Mac 10.13.3 (which is probably my issue). I have an additional question though. Would it be more reliable to switch to MPLAB? Arduino has been consistent enough for me, but last I heard Digilent was moving its focus away from the microcontrollers and
  8. Yeah! At some point I'm going to try playing with Fourier transforms and digitizing recordings. I've got another (related) project involving a toy keyboard that I've disassembled.
  9. I'm just playing around for now but in the future I have vague notions of learning music theory.
  10. Probably, but now that I've got it working I've stopped fiddling with it. Thanks for the suggestion tho!
  11. So I finally figured out my problem, and like all truely frustrating problems it was small and stupid. The formula I used to calculate period: period = CLOCK_FREQ / (1<<PRESCALE * frequency); while mathematically correct, for some reason my usage of defined constants throws the compiler for a loop. The result is that my period was (apparently?) set to 40 MHz every time. I fixed this by breaking it up into components: // Calculate the period we need for our given frequency if (PRESCALE == 7) period = 256; // 1:256 is a special case else period = 1 << PRESCALE;
  12. I'm playing around with timer interrupts on the DP32 using Arduino and the ChipKIT Core. I was surprised to find out that this involves register manipulation. So I can set up timers using register manipulation in Arduino, but I can't seem to do anything else with register manipulation. For example, here is some code of mine which should set up a PWM signal on pin 13 (OC4) of the DP32 using register manipulation, instead of analogWrite() function. Problem is that it doesn't work and I can't figure out why. This problem is exacerbated by the apparent lack of documentation on any of the regi
  13. I was doing some things wrong, so here's some code fixes. Line 52: Carrots "^" are used as bitwise XOR, not power functions. Dunno why I thought they were power functions, but I've changed it to a bitshifted 1 instead. Line 55: I swear the example code I pulled this from just set T3CON to whatever the desired prescaler was. I thought this was screwy but I never questioned it. I've since questioned it. Now I've shifted my prescaler and masked my prescaler onto T3CON. My main problem (i.e. the timer not functioning when prescaler is set to 1:64 or 1:256) has gone away, so that's f
  14. I'm using Arduino 1.6.9 with ChipKIT core and a DP32 rev B. My code sets up an interrupt for timer 3. When I set the prescaler to 1:32 or less, the interrupt runs just fine (although with some quirky behavior that I'll explain below). However, when I set the prescaler to 1:64 or 1:256, the interrupt appears to fail. My code is included below but I'll provide a brief explanation of its function here. The ISR increments a count variable, and sets a flag variable to high. The loop checks to see if the flag is high. If it is, it toggles LEDs 1, 2 and 3 to represent bits 5, 6, and 7 (resp
  15. Well I'm glad you've got a working solution. I wish I could have helped you find a more long term solution. I think I can definitively say that my expertise has been totally tapped out, so I have no idea why your LED lights up when mine doesn't! Ha ha! Good luck with your project!
