I've gotten into the awful habit of submitting before I test. =\ I've tried to power-through the bug but I've spent far more time than I properly have to find the problem.
I stuck a breakpoint into where the wires were being loaded into pin, they were all good, unless I missed one... But when "localConnectedPins" is called, it barfs!! (the wire being pulled is utter nonsense, and it'll segfault when it tries to derefference its pins...) This reeks of memory corruption... I've locked down both wire and pin well enough that they should be very easy to audit, so there's something bugging up the memory. -- I'm pretty sure this is related to why the program misbehaved but didn't crash due to over-reliance on qguardedptr... =\ What might be going on is that something is deleting the wire but not telling any of the pins... THAT WAS IT!! I fixed the destructor in Wire, should be good now. In other news, I assembled all three major sub-units of my DAC, the clock decoder, the input register, and the output buffer into one single HUGE circuit and ran it at 1khz, and was most satisfied with the results. =) (only one channel/8 bits actually implemented still around 50 gates and flipflops.) My current brainstorm is a preamp using a single opamp such as the fairly good TL082 that you can get from some ratshack stores. The problem with usual preamp is that it squanders its dynamic range by using an attenuator followed by a fixed (usually large) gain stage. My solution is to use a quad-gang switched attenuator volume control where the first two decks are attenuation, and the second two decks are stuck in the opamp's feedback loop where they can select from 0- to +10db of amplification. =P They're both wired so that when you turn the control it smoothly shifts from attenuation + buffer to amplification with not one db of gain wasted! =P -- New president: Here we go again...
