linuswck 3f9a4bf140 ld: Block pwr on request if alarm is asserted 
- Align the alarm and pwr up behavior with thermostat temp_mon
 2024-07-26 14:29:46 +08:00
linuswck 201148fb21 main: allow loading flash without device settings 
- Fix bugs: ld & thermostat settings cannot be loaded if device settings
    are not present. But, device settings can be left not configured.
 2024-07-26 11:10:32 +08:00
linuswck a90031dd6c ld_pwr_exc_protector: clear irq bit at pwr up 2024-07-26 11:10:32 +08:00
linuswck 7b52072617 ld: cfg hardware when pd_mon params changes 2024-07-26 11:10:32 +08:00
linuswck c241d34434 gui: fix default units and mv to params' titles 
- siPrefix(eg. m, u, k) is no longer editable and fixed
- the displayed unit is relocated to ctrl panel params' titles
