Silvano Seva 10b8b59e21 Added to MDx tone generator API functions allowing user code to temporarily disable generation of 'beep' tones 2022-05-27 21:48:46 +02:00
Niccolò Izzo f9c23452bc Add plotting function to graphics library 
Added plotting function to graphics library which is native C++, so
refactored the graphics source file to allow that, consequently adapted
the hwconfig header files to be included also in C++ sources.
Propagated compile flags also to C++ sources, including asan what was
previously disabled for C++ compilation units.

Niccolò Izzo 4b498689f5 Replace RRC filter taps, update M17 testsuite 
RRC filter taps have been replaced with the ones generated by Wojciech,
a new baseband for the M17 demodulation testsuite has been generated,
using OpenRTX itself and some further minor changes.

Niccolò Izzo 3163dd49d7 Add M17 demodulator code and tests 
Added implementation of the M17 4FSK demodulator, including clock
recovery, phase detection, and quantization algorithms.
A testsuite is also included to do regression testing against a
reference baseband pre-generated and the corresponding reference
bitstream.

A 1% BER is still present due to a fault likely in the RRC filtering,
since the eye diagram of the filtered stream is bad.
