Member Function Documentation

static void BatteryCharger::setChargingWitness	(	InputGPIO	sensePin,
		bool	negativeLogic,
		bool	enableInternalPullResistor )

static

Set a GPIO pin to sense if the battery is being charged.

Parameters

sensePin	GPIO pin attached to the battery charger chip
negativeLogic	If true, LOW voltage means the battery is charging. If false, HIGH voltage means the battery is charging.
enableInternalPullResistor	If true, the corresponding internal pullup/pulldown resistor is enabled. Set to true if the witness signal works in open drain.

static void BatteryCharger::setExternalPowerWitness	(	InputGPIO	sensePin,
		bool	negativeLogic,
		bool	enableInternalPullResistor )

static

Set a GPIO pin to sense the power wire.

Parameters

sensePin	GPIO pin to sense the power wire
negativeLogic	If true, LOW voltage means there is external power If false, HIGH voltage means there is external power
enableInternalPullResistor	If true, the corresponding internal pullup/pulldown resistor is enabled. Set to true if the wire sensing signal works in open drain.

static void BatteryCharger::update ( BatteryStatus & status )

static

Update the battery status according to the witnesses.

Parameters

[in,out] status Battery status
