A heroic effort to push things forward. Now working includes the I2C interface and the code to talk to and start up the frequency synth. Flip flops are on, frequencies are being divided. No luck on actually getting a signal all the way through though. I currently suspect the transformers or the mixers..... how high can a quadrature sampling detector go again? :/

PSDR 2.5 prototypes are assembled. This commit includes notes for things I want to change or improve (in the notes section of the schematic) as well as preliminary code changes to make it work on this hardware. Display comes on, lots of the parts are working, but no frequency synth yet, so it's hard to know how well the design is working.

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.

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)
