DiSlord 20649012df Little speedup and less size fft 
Better support other size LCD and font
Fix CH1 unstable at begin sweep
 2020-03-30 20:01:51 +03:00
DiSlord 48e28f79d0 Use compact variant sin_cos table in fft (not decrease speed, and need only 208 bytes flash) 2020-03-23 15:10:01 +03:00
DiSlord 9221ad04ca Revert, use sin_cos table in fft.h 
#define FFT_USE_SIN_COS_TABLE by default
Increase code size on 700 bytes, but huge speedup (x3) transform

DiSlord 922b66abdb Move offset variable to si5351.c (better use it as independent library) 
Define and move constants in nanovna.h, and use it
Fix command 'marker' - display marker freq (not current freq)
