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	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
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.	2014-06-22 17:49:43 -06:00
