For enable use external (LSE) clock generator need un comment in Makefile
#UDEFS+= -DVNA_USE_LSE
By default use internal (LSI) clock generator, but it stop then VNA power off
For enable use external (LSE) clock generator, need install 32.768kHz clock quartz on PC14 and PC15 pins, it allow clock run while power off
For enable use RTC in code uncomment in nanovna.h
#define __USE_RTC__
This enable command 'time'
usage: time [y|m|d|h|min|sec] 0-99
Example set 2020 year run 'time y 20'
Add show current time in version screen
Better use font size constants for all screen size
It allow:
- reduce shell thread stack size
- more compact code
- fix some hardcoded scan command code, allow write better scan version
- run calibrate (not depend from pause sweep flag)
Rewrite uint32_t my_atoui(const char *p), now its allow read:
hex 0xaAbBcC1122
dec 12345678
bin 0b00011100
oct 0o12345678
Add some comments
CH_CFG_USE_WAITEXIT (used only is Shell run as thread)
CH_CFG_USE_EVENTS (NanoVNA not use events)
CH_CFG_USE_EVENTS_TIMEOUT (NanoVNA not use events)
Implement stack use check in "threads" command, now free stack space show in table as "stk free" in hex
Check stack usage by sweep, and main threads (seems all ok, but add 64 bytes to sweep)
Replace some const values to defined
