b78769a2caThis 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.

c2b94ddce0Fixes 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?)

2016-06-08 12:18:57 -0600
7e1addf952Almost 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......
Michael Colton
2016-05-29 00:14:03 -0600
f0a4472f27More progress on v2.6 PCB. Almost done. Length matching the signal lines by hand is a bit of a pain..... the version of PADS I have can't do it <rolls eyes>.

8e248a52cdMostly 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.

88d9220f56This 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.
Michael Colton
2016-05-11 16:57:45 -0600
acefe9aa46Seems 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.

2c1530d33fControl 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!

b3ee5db2b4Saving 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.
Michael Colton
2016-04-30 20:55:01 -0600
7c84c19d01Okay! I've got it compiling and largely running on the F7! Still not everything is right, but a lot of it is. I think I am almost there! Maybe I'll get to include the F7 after all :D

59e59d7af1Simple 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?
Michael Colton
2016-04-21 20:55:56 -0600
a211a0b9ddA 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? :/

1890b25a4fPSDR 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.

d784a1b607Cleaning 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.
Michael Colton
2016-03-20 12:06:36 -0600
22fa6da294ZERO unroutes! (Also, there was an extra pin on the MCU, so I added a second LED. Can't let pins go to waste!) I still need to clean up the routing, do planes, and silkscreen, but the worst is over! Backing up.
