88d9220f56 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.

acefe9aa46 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. 2016-05-09 21:49:47 -06:00

2c1530d33f 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! 2016-05-07 15:01:37 -06:00

8b02d73d1c Didn't actually change much. This is testing with the new diode ring mixer. Seems to be working! Thank goodness!! Reception in 2m seems very weak... might need a preamp or something? 2016-05-01 00:49:43 -06:00
Michael Colton
b3ee5db2b4 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. 2016-04-30 20:55:01 -06:00
Michael Colton
7c84c19d01 Okay! 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 2016-04-26 00:21:16 -06:00

a24a6c6b8c I don't know if I am closer or further away. This stuff is hugely frustrating sometimes..... 2016-04-24 00:54:47 -06:00

86a5916626 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. :/ 2016-04-24 00:17:37 -06:00
Michael Colton
57f3365484 Progress on copying stuff over for the F7. I am making quite a mess, I think I sure hope I can reverse this all if I need to!!! 2016-04-23 21:53:10 -06:00

4385f07394 Trying to get the PSDR code to run on the F7 chip. I'd like to use that one if I can. 2016-04-23 21:23:43 -06:00

59e59d7af1 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? 2016-04-21 20:55:56 -06:00
Michael Colton
a211a0b9dd 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? :/ 2016-04-21 00:57:58 -06:00

1890b25a4f 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. 2016-04-18 22:11:10 -06:00

d227015917 PSDR 2.5 PCB Layout is complete! Updated schematics, layout files, gerbers, and some minor changes to the solid models are included. That was brutal! 2016-03-25 09:27:13 -06:00

d784a1b607 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. 2016-03-20 12:06:36 -06:00
Michael Colton
22fa6da294 ZERO 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. 2016-03-16 19:17:51 -06:00
Michael Colton
8d6e6ed844 Lots of progress! Down to about 35 un-routes. So close! Backing up. 2016-03-16 16:02:24 -06:00
Michael Colton
6093ce3cfd Lots of progress on routing. The end is in sight! 156 Unroutes left and almost all the important lines are connected. Backing up. 2016-03-09 16:44:05 -07:00

4ba725120e I am laying out this PCB in the back seat of a truck on my way to Southern Utah. For some reason that feels hard-core. More layout progress. Backing up. 2016-03-03 12:34:31 -07:00
Michael Colton
1b01060d1c More progress. We're at around 200 unroutes and just about all the components have been placed. I am using pin-swapping to make the routing easier and cleaner. 2016-02-24 23:06:14 -07:00

Michael Colton
35e3a24925 Lots of progress. Less than 400 unroutes now. Looks like everything is going to fit! Thank goodness (but....... I can't say that for certain until I'm done I guess.) Backing up. 2016-02-18 23:51:12 -07:00

70440acfa4 Tons of progress today! Still lots to do. (I started at about 1200 unroutes and now I am down to about 750). Backing up. 2016-02-10 23:50:06 -07:00

df9eb8394a Solid progress on PCB layout (it's going to be pretty challenging!) Some changes to the solid model to reflect board outline changes. 2016-02-06 00:42:17 -07:00
Michael Colton
90281f58d8 Further updates to the PSDR2.5 Schematic, basically done. Time to start routing! Due to weirdness in the .PCB file, I am creating a new file and replacing the old, but I wanted to push it before I do that, as a backup. 2016-01-30 21:00:41 -07:00

57a60ce607 Progress on updating the schematic for the PSDR2.5. This is mainly a backup. 2016-01-29 09:14:52 -07:00

569ef2a22c This adds the final encoder board for the PSDR2.5, and includes much progress on the updates to the schematic and a little bit of work on the PCB layout. 2016-01-22 08:51:31 -07:00

0d6854649c Making changes to encoder board for new housing design, started integrating the new RF synth and mixers into the schematic. 2016-01-12 14:07:19 -07:00

3bdb147fdf Some interface improvements. The filter bars now work, and the characters for the filter values are now better. This also improves the performance of navigating the interface. Also, added a basic volume display. 2015-12-30 21:18:31 -07:00

0d13c419cc 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......) 2015-12-29 15:21:24 -07:00

ff84014cf9 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. 2015-11-24 14:29:46 -07:00

43500cbef3 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. 2015-03-06 22:54:22 -07:00
