c2b94ddce0 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?) 2016-11-07 23:23:26 -07:00

468dc41b7c 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.) 2016-07-31 22:05:44 -06:00

7a70b17276 Adds BOM for PSDR2.6, also some notes on the schematic, and defining the pin for charge source control. 2016-06-09 00:35:57 -06:00

8ad6b3ca50 PCB 2.6v is complete and prototypes will get here on Friday! 2016-06-08 12:18:57 -06:00

7e1addf952 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...... 2016-05-29 00:14:03 -06:00

f0a4472f27 More 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>. 2016-05-26 00:49:25 -06:00
Michael Colton
8e248a52cd 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. 2016-05-25 18:23:03 -06:00

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.

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

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

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

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

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

acdbc0749a Backin up my work. Is this a really annoying way to use Git? http://i2.kym-cdn.com/photos/images/original/000/234/765/b7e.jpg 2015-11-17 23:02:17 -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

46c832e409 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) 2014-10-15 09:31:08 -06:00

f694e53e46 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. 2014-10-07 10:31:07 -06:00
