Michael Colton 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
Michael Colton 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
Michael Colton 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
Michael Colton 71b87a38d7 Added a crude Automatic Gain Control (AGC) that's happening on the audio output side. I want to add one for the RF side as well, but I'll need to change the hardware to do it. 
Also fixed some weirdness with the filter menu items.
Verified that the recent changes to applyCoefficients() function are good and necessary to the proper operation of the filter.

Michael Colton 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....

Michael Colton 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
Michael Colton 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.
