linuswck 3ba8b99084 Use degree celsius as temperature base unit 
- Breaking: Erase settings before flashing
- except beta in Steinhart-Hart equation
- to keep the temperature value set consistent with the value returned
- f32 floating point calculation is inaccurate

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.

linuswck a76b8de994 thermostat: Save the user config-ed value directly 
- the firmware recorded the actual value set with quantization errors or
    other errors
- this caused confusion for the user when they read back the settings

- Tested with 0.3A LD output current
 2024-03-21 15:21:24 +08:00
linuswck 607da8a822 ld: Add a delay before turning on LD PWR 
- DAC output might not drop to 0V before PWR is being turned on
- Thus, it might drive nondeterministic current into the laser diode during pwr up
