1aa391bac8 Whoops. Revert to baseband -O3 compiler flag.

8d2a86a499 Change baseband optimization from -O3 to -O2

58e6d26910 Move AudioOutput back to inside audio processor classes. 
Was wasting precious RAM making it static. I lose 400 bytes of .text, not sure why, but I think the trade is worth it.

731cea1b96 Move event.* code into event_m[04].*. 
Slightly more duplication of code now. Need a base class...

Jared Boone
1f3c182b7f Add missing message handler for wideband spectrum. 
Spectrum processing was not enabled, and hence wideband spectrum was not being displayed.

64966d4539 Fix NaNs coming out of angle_approx_0deg27(). 
Used in FM demodulator, was causing downstream problems when using the floating point values directly.

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

eb5b2d7d30 Fix broken audio stats when audio is muted. 2016-01-10 11:34:06 -08:00
Jared Boone
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
Jared Boone
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...

c1e5577669 Eliminate duplicate code between event_m4.hpp, event.hpp. 
event.* is common code, _m0 and _m4 contain specific event mask definitions.

229c1e9a3c Move M4 MAPP IRQ handler to be with the event handler class. 
event.[ch]pp and event_m4.[ch]pp are looking almost the same now...

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.
 2016-01-04 11:49:39 -08:00

6d3cdb9bbf Separate template/callback code from method code. 
...for more small reductions in code size.
