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.)

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......

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>.

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.

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.

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!

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.

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.

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.

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.

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.

Tons of progress today! Still lots to do. (I started at about 1200 unroutes and now I am down to about 750). Backing up.

Solid progress on PCB layout (it's going to be pretty challenging!) Some changes to the solid model to reflect board outline changes.

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.

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.

Making changes to encoder board for new housing design, started integrating the new RF synth and mixers into the schematic.

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.

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.)

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

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.

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.

Backing up. PSDR2 has reached the point where it could be produced and would work; all lines are routed and there are no clearance issues. I am cleaning up the layout now, need to do some planes, silkscreen, then I am DONE.

Backing up. Cleaned up component placement a lot. Made moats around circuit blocks so there is room for vias. I also like the idea of the blocks being separated, maybe even labeled. I'll do it if I have room. Need to redo almost all of the routing, then I'll be ready to move the MCU into place and start hooking it up! Lots of work to do, but it's coming along very nicely :D.

More progress on PSDR2. Schematic is basically complete (at least, all the components and blocks are in, though some connections between blocks and to the MCU are not in there yet.) Also started layout. Location sensitive components have been placed. It's going to be so cool!

Initial commit to GitHub.
...
Includes the Source (as an Eclipse project) and the Hardware files (including schematic, layout, gerbers, and bill of materials.)
The firmware is extremely incomplete. At this point the DDS chips work (with controlled phase relationship), the LCD (with fast-ish SPI, scrolling, and GFX, modified from Adafruit's library), the encoder knob, and LED work.
The ADC is capturing, but not in a usable way, but it's enough to feed the DSP code and see a nice pretty waterfall. Timers, interrupts, and DACs are not working yet.
