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

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

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

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

7b8b1ac023 Starting to (slowly) make changes to the schematic for the next hardware version. 
Making/made a lot of changes to the graphics and some to the menu system. Want to do a commit before I change too much more, incase I screw things up, you see. Graphics look much better!

a9f466d396 Added some color bitmaps and some code to draw them (way prettier graphics, here we come!), fixed a minor bug in the mode selection menu. 2014-07-23 09:31:17 -06:00

31de146601 The main thing here is moving the FFT/Filtering/IFFT to a timer interrupt that has a lower priority than the audio capture/playback timer interrupt. This way I don't care how slow the display code runs in the main loop (for now) enabling me to have the audio processing and the display working at the same time. 2014-07-14 01:41:46 -06:00

7b1da77c21 Haven't committed in a while :o . Currently waterfall is disabled while I work on audio processing. I am capturing, FFT, filter, IFFT, and output. It seems to be working partly. I don't think I am doing things right yet. 
Also, starting to implement the menu system. Oh, and fixed some indentation, so it looks like there was more changed to main() than there really was....

8c308e12c0 Got a timer up and going, and it's firing interrupts! Next up is to change the audio capture to use the interrupt and some buffers. Basically separate the display loop stuff. 2014-06-23 00:00:31 -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.
