This is a major architectural change. It's based on STM32CubeMX building a Makefile project with a lot of the configuration already done automatically. The reasoning being that they'll get right on the first try what I have to torturously fiddle with. And the result? With minimal effort, I already have a build that is more portable to develop on, uses the latest drivers, includes FreeRTOS, and I've already got DMA video working pretty much perfectly (though not 100% optimized and tested). This is also giving me a convenient opportunity to massively clean up my code and just a few tricks I've learned since writing the old code. So far so good!! BUT! It can't do any radio like things yet, none of that is implemented at al, no interface, no audio, etc.

Dude, this DMA thing is killing me!!! I can write to the display at blistering speeds, but there are errors in the picture and I can't figure out why! <pulls all hair out!>

Further progress on DMA. The radio is now "usable" with it turned on. There is a whole lot of weird corruption to the graphics... anyway, it's progress and I want to make sure it's saved.

Fixes very basic transmit support. Adds assembly instructions. Cleans up the Solid Model a little and moves older items to an Archive folder (basically to make sure they are okay to delete, since Git is keeping a history, there is no real reason to have an archive folder, right?)

Almost done with PCB 2.6v. I decided to change the reference designators so it's easier to find components. But PADS randomly swapped a bunch of parts. I wasted HOURS fixing it! :( Anyway, it's almost done, and the new reference designators are going to be nice..... maybe not totally worth it......

Mostly changes to the PCB and schematic. This is PSDR v2.6, and it's almost done. I am committing here as a backup. Also changed the code to use internal pull-ups for the I2C.

This fixes (I think) the ADC issue. Or rather, interprets the already correct values correctly. Anyway. I think we are good, though more testing would be nice. I compared the F4 display performance to the F7 to see if the flickering/shimmering effect was there. It was not..... because the display was scrolling so slowly by comparison! The F7 is so fast that it was sometimes calculating and drawing the waterfall twice! Should be better now, but I may want to slow it down further. Also some changes to the power up/clock settings functions. Turns out there were two, not sure which is better or more complete. They both work well enough for now.
...
So with this, I think the F7 is now doing everything the F4 was doing, and can become the official chip of the next board revision.

Seems I've pretty much got the F7 working now. There is still something weird with the ADC not returning the right value.. Also, the screen looks shimmery if viewed from the right angle. I've never noticed it before. Not sure if that's the F7's fault? Saving here so I can try the F4 again to compare.

Control of the new frequency synth is pretty much working (not completely optimized, probably isn't taking full advantage of its resolution, and doesn't cover its full range yet) the PSDR can now tune from 2.5MHz to 175MHz! Sensitivity isn't great (currently around -90dbm on 7MHz and about -80-85dbm on 146.4MHz. Still pretty cool!

Saving current progress. Still some weird issues. Having trouble with I2C (again! It was such a pain to get working on the F4) and also something with the ADC I think.... I suppose it could be assembly issues of the F7 board too.... Hmmm.

Simple test that the GPS module is indeed talking and the MCU can indeed hear it. It's dropping characters though, and it's polling based and whatnot, so it will need to change fast. Also, so far, in my office, the GPS hasn't gotten a lock. Is the antenna good enough? How about the antenna match?

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.

Cleaning up the routing, a lot! At this point the goal is to increase performance, reliability, and manufacturability, but there is also an element of making it look good and being a perfectionist. I won't go too much longer. Backing up.
