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

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

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.
