Enumeration Type Documentation

enum BALLAST_MODE

Ballast pump state machine.

Enumerator:

WAIT_ACTIVATION	Wait 90 minutes after boot or higher than BALLAST_HOLD_ALTITUDE to activate ballast pump.
CONTROL_ALTITUDE	Determine if altitude is less than BALLAST_HOLD_ALTITUDE.
PUMP_RUN	Run the ballast pump.
PUMP_RUN_DELAY	Time delay after ballast pump runs to determine effects of fluid loss.
