!!!!! Don`t understand why si5351 non stable on band 2 then change from band 3
It fixed if set before sweep one frequency from band 1 (for example 50MHz)
Possibly problem in tlv320aic3204_set_gain, call only si5351_set_frequency_with_offset not work
Little faster call command from shell
Fix interpolation if points < POINTS_COUNT
In plot.c prepare for 8bit/pixel mode (test, allow increase cell buffer size by use 4 or 8bit/pixel mode, but not need for now)
main.c little change wait execute shell command in sweep thread
Use int64_t acc for values
Use double on calculation
Not cache freq on si5351_set_frequency_with_offset (to fast change in rare cases on cw mode, and process wrong DSP block) as i write before need change DSP delay tactic
Little code optimization
Add commented 600kHz I2C bus timings (work, give x1.5 speed, but need change DSP ready timings not by wait_count, need use chVTGetSystemTimeX() its better)
DSP_START(delay)
//================================================
// Place some code thats need execute while delay
//================================================
DSP_WAIT_READY
Fix Band table description
Add power stabilization delay on sweep start
Start/stop generation feature (unstable on segment scan from CPU)
Calibration on paused sweep (need more stack, need find better solution)
Variable use optimization
Cleanup and optimize code
Add comments, fix definitions
Fix rounding errors
Fix band 1 stability
mcuconf.h
Set I2C bus clock to SYSCLK (more fast)
Apply 400kHz bus I2C clock timings for 8MHz and 48Mhz clock
main.c
Remove and reset some variables
Add separate sweep for calibration (allow calibrate if sweep paused)
Increase main thread stack (need for run calibrate, possibly need execute some commands in sweep threads for reduce stack usage)
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
