5dac0bbe49 Squelch special case when threshold == 0, do not squelch. 2016-01-10 20:16:21 -08:00

01df79641c Rename squelch algorithm variable for clarity.
Helps to understand meaning of threshold.

497adda390 IIR default constructor passes no audio.
Debugging mechanism -- filter must be configured to pass audio.

4ea84301c6 For non-audio modes, don't bother muting audio.
It's assumed base class will start with audio muted.

d6f797540d Remove baseband message from queue after it is processed.
Application code can now wait on queue empty and know the baseband's state.

136ba895ef Clear spectrum FIFO when streaming is stopped. 2016-01-10 11:00:09 -08:00

62e5ec1dbb Postpone clearing channel_spectrum_request_update until finished with data in array.
There was potential for new samples to be copied into array as the FFT and post-processing were occuring.

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.

0647f26707 Move SGPIO configuration and control to baseband firmware.
Addresses long-standing and annoying bug where SGPIO DMA channel would not disable -- and not configure cleanly next time it was needed. My theory is that the DMA channel couldn't disable until it got a request from the peripheral, and sometimes the peripheral was disabled before that last request.

Anyway, the baseband firmware should control the SGPIO, methinks, despite the impact on baseband code size.

c75c167c25 Rename GPDMA channel disable_force() to disable().
There was nothing particularly forceful about the disable_force() code. Whether it's a "forced" operation depends on what happens before and after (HALT and ACTIVE flags are involved in a smooth disabling of the channel).

365c2ef946 Handle baseband::dma::wait_for_rx_buffer() returning empty buffer.
Was technically OK before, because sample count was zero. But seems silly (and vaguely dangerous) to call all that code with a nullptr.

7710b2d1fa ChannelSpectrumConfig message subsumes FIFONotify.
Separate channel spectrum config from spectrum data. This will permit sending config info only when necessary.
Use type information of ChannelSpectrum to statically define number of FFT bins elsewhere.
TODO: Posting configuration message way too often. Fixing that is the next step.

aaa1bc3a09 Transmit ChannelSpectrum data through separate FIFO.
Allows handling of data during LCD "vertical retrace", independent of other baseband->application messages. A bit kludgy still...

b42d3cc9d5 Move BasebandStatsCollector code into .cpp, as much as possible.
Still have template for callback, but hopefully will mitigate bloat when BasebandStatsCollector is used in multiple places.

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.
