4c2ab407f5 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. 2014-09-13 17:48:18 -06:00

9439b576fd So tired. Time for bed. I'll finish it tomorrow. 2014-09-12 22:58:31 -06:00

44e5663274 Backing up. All components placed and only a few routes left. Cleanup, and other finishing details will happen next. Almost there.... 2014-09-12 17:03:20 -06:00

4f7c43aa12 Except for the microcontroller, component placement and routing is complete. Now it is time to start doing that..... 2014-09-11 17:21:50 -06:00

15efd49cde Backing up. Routing is coming along very well. Getting close! 2014-09-11 12:31:40 -06:00

2e3f852f88 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. 2014-09-10 08:36:18 -06:00

d110ec9f47 Started at about 900 unrouted traces, now I'm down to about 135. Not bad. 2014-09-08 00:05:49 -06:00

96076b56d7 Preliminary component placement is basically complete. Saving as a backup. 2014-09-07 18:24:50 -06:00

f8ec3099b8 More progress. Just committing as a backup. 2014-09-06 22:13:56 -06:00

6c9d585c8a 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! 2014-09-06 19:14:59 -06:00

ffcb904b66 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.
