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
 2020-04-02 22:11:32 +03:00
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
 2020-03-21 21:58:51 +03:00
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
