Includes the Source (as an Eclipse project) and the Hardware files (including schematic, layout, gerbers, and bill of materials.) The firmware is extremely incomplete. At this point the DDS chips work (with controlled phase relationship), the LCD (with fast-ish SPI, scrolling, and GFX, modified from Adafruit's library), the encoder knob, and LED work. The ADC is capturing, but not in a usable way, but it's enough to feed the DSP code and see a nice pretty waterfall. Timers, interrupts, and DACs are not working yet.
