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 c322d5e3cb Add limited variable offset support, and constant sin_cos tables for various offset and ADC speed 2020-04-29 13:43:32 +03:00
DiSlord c572e66231 Allow better si5351 generate frequency less than 50k 
Small speedup DSP processing, less size
Add Cortex M4 DSP instruction support

DiSlord e09ee19646 Move bandwidth option from properties to config 
Little fixes
 2020-04-02 16:36:59 +03:00
DiSlord 2ed2f96f4a Size fixes 
- bandwidth count stored in menu (less error on add new values)
- allow set any bandwidth count from command
- bandwidth command print bandwidth freq on apply

DiSlord 4a44ecc37c Fix comment 2020-03-21 16:47:32 +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
