C++ (Cpp) BATTERY_CHARGE_ENABLE Examples

Example #1

File: Battery.cpp Project: RAFACG/IndependentlySmartWatch

static int timerBattery(TimerHandle timer, void *context)
{
	// Initiate battery charging control
	BAT_CHARGE_OUT |= BAT_CHARGE_OPEN_DRAIN_BITS;
	BATTERY_CHARGE_ENABLE();

	// Fire off another timer, to wait a while
	Timer_Create(timerChargingControl, NULL, 50, 0);

	return 0;
}

Example #2
