We've squashed the bugs and straightened out the kinks... Here's the first screenshot of real data coming in from the ADC! We use pyqtgraph for the data rendering, which performs excellently and has all the plotting and UI features we want baked right in, so we've avoided sinking a ton of time into displaying the waveform. Tomorrow we will add the actual units to the GUI and support setting the parameters of the device, and on Friday we'll have the real boards in our hands.

(disclaimer: we're driving the ADC directly with a function generator here, just for simplicity's sake)

(also disclaimer: we're not using a teensy and I don't know why Windows thinks it is one, only on this computer does it say that...)
