Jared Boone
9cab3c9978 Remove message_map from Context. 
It doesn't belong in a display/rendering context object, it has much broader significance, mostly distributing messages via the M4->M0 IPC mechanism.
 2016-01-13 15:46:04 -08:00
Jared Boone
731cea1b96 Move event.* code into event_m[04].*. 
Slightly more duplication of code now. Need a base class...

Jared Boone
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.
 2016-01-10 10:42:20 -08:00
Jared Boone
8fde4972b4 Methods to peek and skip messages in queue. 
Allows receiver to not consume a message until after it's handled. And that enables the transmitter to block until the queue is empty, knowing that when unblocked, all messages in queue have been handled.
 2016-01-10 10:15:25 -08:00
Jared Boone
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).
 2016-01-10 10:11:16 -08:00
Jared Boone
43d6098c48 Move baseband_sgpio.* to common/. 
It'll soon be used by M4 code, not M0. SGPIO baseband streaming needs to be tightly controlled by... the baseband!
 2016-01-09 17:57:37 -08:00
Jared Boone
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.
 2016-01-09 12:20:57 -08:00
Jared Boone
8fba47b7d8 FIFO in and out indices should be volatile. 
Later code revealed that the receiving core never notices (reads anew) the _in member variable when waiting for the FIFO to be empty (_in == _out).
 2016-01-07 10:53:27 -08:00
Jared Boone
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.
 2016-01-06 12:10:30 -08:00

ba33cc737d Transmit DisplayFrameSync message, handle in WaterfallSpectrum. 
More kludginess, especially around initialization and timing. But it addresses the flickering lines of pixels at the bottom of the waterfall scroll area!
 2016-01-06 11:36:57 -08:00
Jared Boone
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.

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
65dd385c94 Little FFT loop indexing tweak. 2016-01-03 17:47:08 -08:00

0497dbf62f NBFM configuration message.

 2016-01-03 12:46:21 -08:00

c179b9e1cd Move FIR filter configs to common/, so M0 can use it.

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
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?
 2015-12-24 10:36:26 -08:00

fa3eaf0820 Disable audio codec wait-for-zero-crossing volume change mode. 
This may explain (now unreproduceable) issue where UI volume changes weren't always changing the gain on the audio codec.
 2015-12-14 12:26:41 -08:00

b058d609eb Move packet timestamping into baseband. 
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.
 2015-12-12 11:37:30 -08:00

42d13e6713 ui::OptionsField match option value by ==, not >=. 
I think I used >= to match baseband filter bandwidth, but then the options would all have to be in increasing order to do the right thing, which is not what another developer would expect!

85383e488b std::fma not necessary with proper compiler options. 
std::fma isn't available on Ubuntu 15.04 arm-gcc, apparently. Hence my reviewing this code...

RRC filter alone will do the trick!

9e694ce836 AIS decoding and really bad UI. 
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.

a366b3ac4f CRC class. 
Has some more efficient code, commented out because I was having trouble getting it to work. However, it may have been due to the particular data I was trying to decode and CRC-validate.

f82fd1f8d7 Tease apart utility.hpp, other header dependencies. 
Trying to get a host-testable FSK demodulator, and finding a lot of M4- and ChibiOS-specific code is getting included. Boo.
