DiSlord 237a329226 Add sin_cos table for 6 or 12kHz offset for dsp 
Add support direct clock for AIC3204 from si5351
Now possible made calibration and not reset old calibration data, just made another calibration (not need reset or disable correction).
  Open - Short calibration depend from self, need recalibrate it together.
  Load calibration possible made alone
  Isoln, Thru also depend from self, need recalibrate it together.

DiSlord 2f7f2a2473 Fix AIC NADC to 1 
Fix 300-900MHz gain to 50

DiSlord a1bbee724c Add support 96kHz ADC, allow increase sweep speed and bandwidth to 2kHz 2020-04-29 14:34:05 +03:00
DiSlord 22e4df1577 Little rework bandwidth: 
- Not reset sweep on request
- Better menu response
- little DSP optimization

Faster i2c bus (now 600kHz, allow more faster add settings)
Add i2c command (disabled by default)
Little fix stat command

TT 0d407577f8 style: uniform code style and untabify 2020-03-21 09:33:33 +09:00
DiSlord b77e1d6680 Big work around si5351 generator 
Improve sweep speed about 60%
Stop generation on pause sweep
Remove all hack for si5351
Reduce code size
Fix integer overflow on big freq values

Additional
Change I2C

Others:
 move marker_tracking variable to ui config
 move some definition to correct place
 reduce tlv320aic3204 code size
 Speedup marker move from lever (BUTTON_REPEAT_TICKS = 625)

Need test stability
