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!>

Semi working DMA code for the display driver! So excited! Now to work out the bugs :)

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?)

PSDR 2.6.1 PCB complete. Updates to BOM in preparation for order. Also added a little bit of code to turn off printf statements when not debugging (otherwise the board wont run without a debugger attached.)

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.

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.

Progress, I think. The thing compiles and builds something, but it's only 1K and won't run. Trying to figure out what I am doing wrong. :/

Trying to get the PSDR code to run on the F7 chip. I'd like to use that one if I can.

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.

Making changes to encoder board for new housing design, started integrating the new RF synth and mixers into the schematic.

Got trace statements though the debugger! Cool! And it was so minor. Also, fixed a weird issue with missing linker files (at least on this computer......)

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.

Getting my other computer synced up, there might be some bumps. I still stink at Git.

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.

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.

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.
