fe1a6c09bb Clean up baseband processors to each have a main(). 2016-07-24 21:42:11 -07:00
Jared Boone
500a651bcf Give Processors a run() function. 
So main() can call it, start a Processor linked in to the baseband binary.

3e08318012 Pass CaptureConfig to StreamInput as pointer. 2016-04-27 10:31:37 -07:00
Jared Boone
91ee2dbb67 Move FIFO and write size to CaptureConfig structure. 
Now configured from baseband, where write size and appropriate FIFO size is known.

d5e21ce972 Use CaptureConfig to share state between cores. 
Remove awful FIFO_HACK.
TODO: Lots of repeated code...
TODO: Capture thread is signalled too frequently.

0c29308eb9 Fix FM squelch. 
Forgot to recalibrate when adjusting normalization of float/audio signal path.

a558565886 Further template BlockDecimator by element type, use for audio buffer. 
Appropriating for use as a buffer accumulator that will save up enough audio samples to put into an audio DMA buffer.

aead1d8798 Change NBFM audio fs->24k, AM ->12k. 
Send channel decimation factor from application to baseband.

d821afc60d Spectrum streaming control, spectrum attributes back in each frame. 
TODO: This feels kinda complex, and there's some repeated Processor code that needs to be refactored into a base class.

222b878629 Use BasebandProcessor::mute_audio(), remove I2S #include dependencies. 2016-01-04 09:07:07 -08:00

8fb3ffaedc Reorder squelch code to group things a bit more logically. 2016-01-04 09:01:51 -08:00
Jared Boone
d9017530c6 Moved baseband temporary buffers back into class member variables. 
Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.

fea5dd536f Move baseband working buffers from member variables to stack. 
It's temporary, after all...

7de80edcd3 Move baseband FIR filter defs to common file. 
They will likely be shared with multiple decimators/demodulators.
Also added normalized filter pass/stop values to each set of taps.

bbfcca8ec0 Rebake of AM, NFM demodulators -- more flexible filtering/configuration. 
Also make SpectrumCollector dynamically configurable.
Add deemphasis filter to NFM.

088f60f2bc Extract spectrum collector from BasebandProcessor. 
Code size improvement, and less confused classes. :-)
