Michael Colton 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
Michael Colton 53263f2416 Merge branch 'PSDR2.5_PCB' 2016-05-01 00:57:05 -06:00
Michael Colton 46dc8ad0af Trying to merge, it wants me to commit stuff first. 2016-05-01 00:56:50 -06:00
Michael Colton 155b2700d4 Oops, didn't actually commit the files. 2016-05-01 00:50:49 -06:00
Michael Colton 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 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
Michael Colton 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
Michael Colton 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
Michael Colton 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
Michael Colton 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 e74f299d5e Further updates to PCB and Schematic. Backing up. 2016-02-24 12:49:30 -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
Michael Colton 760a6aeae9 More progress on PCB layout. Backing up. 2016-02-13 14:37:21 -07:00
Michael Colton 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
Michael Colton fc179fae46 Continued progress on the layout. Backing up. 2016-02-10 16:23:27 -07:00
Michael Colton 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
Michael Colton 57a60ce607 Progress on updating the schematic for the PSDR2.5. This is mainly a backup. 2016-01-29 09:14:52 -07:00
Michael Colton 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
Michael Colton 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

Michael Colton 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
Michael Colton 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

Michael Colton 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
Michael Colton acdbc0749a Backin up my work. Is this a really annoying way to use Git? 2015-11-17 23:02:17 -07:00
Michael Colton d81b06c5d5 Saving progress on PCB update. Probably going to be a lot of these soon. 2015-11-14 01:08:38 -07:00
Michael Colton 3236178786 Syncing some more, not sure if these are more or less up-to-date than what's on here already..... 2015-11-14 00:04:20 -07:00
Michael Colton c90ef72637 Updating Main PCB 2015-11-13 23:54:46 -07:00
Michael Colton a84fd4cb4b Getting more files synced up. Organizing things. This includes all the keychain files. I forgot to upload them sooner! 2015-11-13 23:44:39 -07:00
Michael Colton 674b3ef033 Getting the solid models up to date. 2015-11-11 18:11:47 -07:00
Michael Colton b0b9e92391 Getting my other computer synced up, there might be some bumps. I still stink at Git. 2015-11-11 17:54:39 -07:00
Michael Colton 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

Michael Colton d9c9939ab8 Update to bring github up to date with my files. 2014-10-28 00:36:55 -06:00
Michael Colton 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
Michael Colton 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
Michael Colton d04d7845cf Initial transmit support. Internal microphone working. Capacitive touch sensors working. Currently touch TOUCH1 to transmit, waterfall changes color and shows the filtered output that should be transmitted (except that it's MUCH noisier than it looks, due, I think to DSP issues.) 2014-10-06 11:03:34 -06:00
Michael Colton 7f0b21569c Just backing up. PSDR2 is receiving well, image rejection is good. Gain pot settings work. Audio out works (to earphones only, the speaker fails pretty badly, not sure why, but that's hardware anyway) 2014-10-01 10:48:27 -06:00
Michael Colton 817dcff56e Enclosure 3D files, Assembly Diagrams and Assembly Guide. Also so work on getting the firmware compatible with the PSDR2 hardware. Probably some junk as well. Lots of files. 2014-09-28 20:40:01 -06:00
Michael Colton 7742b85c6a PSDR2 Release. Schematic, layout, and gerbers complete. PSDR1 gerbers moved to Old folder (probably should just call it PSDR1...) Started (and almost finished) Encoder daughterboard. 2014-09-18 12:06:24 -06:00
Michael Colton fde421cc95 Backing up. Routing is looking good. Just planes and silkscreen to go! 2014-09-14 01:28:11 -06:00
