Upload of my development on my work computer. This includes some efforts to get serial working for the GPS (I think) and maybe some experimental transmitting test stuff? Anyway, mostly included here for completeness, and because I will not be doing PSDR development on this machine anymore.

Backin up my work. Is this a really annoying way to use Git? http://i2.kym-cdn.com/photos/images/original/000/234/765/b7e.jpg

Honestly, it's been a while since I did any coding, with getting the kickstarter ready, so I don't actually remember what the state of the code is right now. I think I was working on getting the UART up so we can use the GPS. I'm commiting this as more of a backup than anything.

Pretty big improvements to bitmap drawing code, and waterfall display code. Also a hack to deal with the red-things-stay-red bug (it's not ideal, it just blocks the encoder tick() if the display is drawing, doesn't seem to effect the feel of the interface in a bad way. Beginning to include GPS support. Working on some other display speedups (DMA and 16bit transfers, both are currently disabled)

Big improvements to audio! I was doing overlap-add wrong. There are still issues, but it's much better. Also, changing modes between LSB/USB/AM works now (though the menu doesn't show USB correctly, and the filter bar doesn't change). Improvements also effect transmitted audio.

Initial transmit support. Internal microphone working. Capacitive touch sensors working. Currently touch TOUCH1 to transmit, waterfall changes color and shows the filtered output that should be transmitted (except that it's MUCH noisier than it looks, due, I think to DSP issues.)

Just backing up. PSDR2 is receiving well, image rejection is good. Gain pot settings work. Audio out works (to earphones only, the speaker fails pretty badly, not sure why, but that's hardware anyway)

Enclosure 3D files, Assembly Diagrams and Assembly Guide. Also so work on getting the firmware compatible with the PSDR2 hardware. Probably some junk as well. Lots of files.

PSDR2 Release. Schematic, layout, and gerbers complete. PSDR1 gerbers moved to Old folder (probably should just call it PSDR1...) Started (and almost finished) Encoder daughterboard.

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.

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.

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!

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.

Further improvements to the menu system. Now, rather than a red underline, the item itself turns red. Logic for updating runtime settings and updating the display is improved. Main() is streamlined. Looks rather nice, if I do say so myself.
...
Does seem a little slow sometimes. Not sure why it would be (not more than it was before, anyway) Also, if you move through menu items too fast, some of them stay highlighted incorrectly.

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!

Huge improvement in display. It was basically a bug that made it so hard to read. Playing with an IF shift feature, and filtering and stuff. I think the overlap-discard is not quite right yet....

Starting to implement overlap-discard in the DSP code. I think maybe I've gotten it working, with a pretty large improvement in audio, but reception was so bad I had a hard time finding things to listen to to test it with. Also added the ability to switch mode (LSB & AM).

The beginnings of AM demodulation. I think it works, but it doesn't sound good at all (then again, SSB leaves something to be desired as well.) Graphical display of filter (nice!) Doesn't crash if you set the FFT size to 1024.

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.

Added a crude Automatic Gain Control (AGC) that's happening on the audio output side. I want to add one for the RF side as well, but I'll need to change the hardware to do it.
...
Also fixed some weirdness with the filter menu items.
Verified that the recent changes to applyCoefficients() function are good and necessary to the proper operation of the filter.

Menu system is improved. Arbitrary filter control is working pretty well. You can set the upper and lower bounds of the filter and that's pretty neat! Strange to say, but this radio now beats my Yaesu FT-817 for filter performance (by a whole lot).

Haven't committed in a while :o . Currently waterfall is disabled while I work on audio processing. I am capturing, FFT, filter, IFFT, and output. It seems to be working partly. I don't think I am doing things right yet.
...
Also, starting to implement the menu system. Oh, and fixed some indentation, so it looks like there was more changed to main() than there really was....

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.
