Backing up. PSDR2 has reached the point where it could be produced and would work; all lines are routed and there are no clearance issues. I am cleaning up the layout now, need to do some planes, silkscreen, then I am DONE.

So tired. Time for bed. I'll finish it tomorrow.

Backing up. All components placed and only a few routes left. Cleanup, and other finishing details will happen next. Almost there....

Except for the microcontroller, component placement and routing is complete. Now it is time to start doing that.....

Backing up. Routing is coming along very well. Getting close!

Backing up. Cleaned up component placement a lot. Made moats around circuit blocks so there is room for vias. I also like the idea of the blocks being separated, maybe even labeled. I'll do it if I have room. Need to redo almost all of the routing, then I'll be ready to move the MCU into place and start hooking it up! Lots of work to do, but it's coming along very nicely :D.

Started at about 900 unrouted traces, now I'm down to about 135. Not bad.

Preliminary component placement is basically complete. Saving as a backup.

More progress. Just committing as a backup.

More progress on PSDR2. Schematic is basically complete (at least, all the components and blocks are in, though some connections between blocks and to the MCU are not in there yet.) Also started layout. Location sensitive components have been placed. It's going to be so cool!

More schematic progress. The VNA stuff is mostly done!

Saving progress. Nothing to see here. Updates to schematic and BOM.

Mostly just a commit so I have a back up of my work. Continued progress on next revision of hardware.

Looking at adding PJRC optimized display code to the PSDR. But his chip is rather different (no hardware FIFO) so I'll need to implement the changes with DMA I think, I'm sure it will work well, but it's going to be some work.... Update to block diagram. Also, finally getting to work on next rev of hardware!!

Has the beginnings of an S-Meter. Audio seems worse than before that was added, so I want to check on that. Uploading the image files (even though the PSDR uses them in code form... still, might be handy)

Added block diagram in a few formats. This is for the complete design, hopefully most/all of this will make it in the next board revision. Look at all that stuff!!

Added basic volume control (not sure why I didn't do that a long time ago!) also a HackADayPrize logo, can't hurt, right? A few other small things.

Starting to (slowly) make changes to the schematic for the next hardware version.
...
Making/made a lot of changes to the graphics and some to the menu system. Want to do a commit before I change too much more, incase I screw things up, you see. Graphics look much better!

The main thing here is moving the FFT/Filtering/IFFT to a timer interrupt that has a lower priority than the audio capture/playback timer interrupt. This way I don't care how slow the display code runs in the main loop (for now) enabling me to have the audio processing and the display working at the same time.

Got a timer up and going, and it's firing interrupts! Next up is to change the audio capture to use the interrupt and some buffers. Basically separate the display loop stuff.

Added PDF of schematic, and moved the gerbers a little.

Initial commit to GitHub.
...
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.
