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).

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.

Transmit DisplayFrameSync message, handle in WaterfallSpectrum.

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?
