History
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

Enclosure 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
Gerbers 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
Keychain 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
Logos & Silkscreen Art 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
PSDR 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

Test Boards 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

Block Diagram.pdf Added block diagram in a few formats. This is for the complete design, hopefully most/all of this will make it in the next board revision. Look at all that stuff!! 2014-08-11 23:05:17 -06:00

Block Diagram.vsd Looking at adding PJRC optimized display code to the PSDR. But his chip is rather different (no hardware FIFO) so I'll need to implement the changes with DMA I think, I'm sure it will work well, but it's going to be some work.... Update to block diagram. Also, finally getting to work on next rev of hardware!! 2014-08-23 14:08:17 -06:00
Bottom Assembly Diagram.pdf 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
ComponentPlacement.txt 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
PSDR Schematic.pdf Update to bring github up to date with my files. 2014-10-28 00:36:55 -06:00
PSDR.pcb 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

PSDR1_BOM.xlsx 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

README.txt Added PDF of schematic, and moved the gerbers a little. 2014-06-22 17:59:36 -06:00
STM32F429_Config.ioc 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
STM32F756_Config.ioc Trying to merge, it wants me to commit stuff first. 2016-05-01 00:56:50 -06:00
