b03da8d693 Fix calculation of work_audio_buffer item count. 2016-01-03 22:42:40 -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.

5547782f5a Improve FFT twiddle factor precisions using Python SymPy. 
Python math, numpy, scipy produce values with significant rounding errors.
 2016-01-03 21:02:44 -08:00
Jared Boone
963b6e257a FFT twiddles can be used for all K <= table length. 
Change assert to allow FFTs < 8.
 2016-01-03 20:25:31 -08:00
Jared Boone
54e59cc224 Hard-code K=8 FFT twiddle constants for now. 
So low on baseband RAM! This eliminates the sin_f32() function and table, which is only used in the FFT, for the moment.
 2016-01-03 20:08:26 -08:00

Jared Boone
07cd99d85d Removing baseband MessageHandlerMap. 
It's a bit heavy (362 bytes smaller with switch/case implementation), hard to access to add/remove handlers, doesn't bubble events like I'd like. (I'm going to bubble events to the baseband processor shortly.)
 2016-01-02 22:54:09 -08:00
Jared Boone
fea5dd536f Move baseband working buffers from member variables to stack. 
It's temporary, after all...

 2015-12-30 12:20:25 -08:00

Also added normalized filter pass/stop values to each set of taps.
 2015-12-30 12:19:42 -08:00
Jared Boone
3db0820b54 Remove LOCATE_IN_RAM from DMA IRQ handler 
Not needed for M4, was causing code to be located in data RAM, and veneers to jump between code and data RAM. Reclaimed a few hundred bytes of code RAM.
 2015-12-29 11:24:23 -08:00
Jared Boone
bbfcca8ec0 Rebake of AM, NFM demodulators -- more flexible filtering/configuration.

df593c2f0f Run codec at 1 x baseband sample rate. Do not use CPLD decimator.

b8726b6ecf Un-bitfield PinConfig, GCC 5 didn't like it. 
And GCC 4.9 was very touchy about it. Attempts to fix by other means broke MAX2837 register readback (but not writing?). It suggests there might be a deeper issue -- setup/hold timing?

bddd26d557 Perform frequency-domain windowing of spectrum.

 2015-12-20 13:31:00 -08:00
Jared Boone
b38338efc0 Keep MAX2837 in standby so temperature can be read.

Now reads the RTC peripheral at the end of each received packet.
TODO: Improve resolution to milliseconds or better.
TODO: Work back from end of packet to compute timestamp for beginning of packet.
TODO: Reuse ChibiOS RTC code, which isn't used now because ChibiOS on M0 core is responsible for RTC configuration, and including ChibiOS RTC API on M4 will also try to initialize/manage the peripheral.

bb3cb6f080 Push packet timestamping earlier in packet handling.

Half the amount of tap memory required.
Performance is significantly degraded due to greater flexibility -- most likely due to separate sample buffer shift phase, instead of performing shift during output sample calculation.

45d26abf10 Use correct memory region for persistent storage. 
Turns out 0x10088000 - 0x10089fff is not the right place. It's 0x40041000, and is only 256 bytes!
Move PPM to correct place, change representation to PPB for finer control.
Reset PPB value to initial value if read value out of bounds.
Clip PPB value on write to permitted bounds.
Contributes to resolution of issue #11.
