Static Public Attributes
constexpr static uint32_t	counter_modulus = (1U << 24)
	Modulus for the 24-bit RTC counter.

	Mask for the 24-bit RTC counter.

Detailed Description

Wrapper around the nRF51 RTC peripheral.

Note: When a soft device is used RTC0 is restricted to the soft device. RTC1 is available to applications, but is probably taken by clock::uptime.

Member Function Documentation

constexpr static unsigned int nrfcxx::periph::RTC::counter_delta	(	uint32_t	a,
		uint32_t	b
	)

inlinestaticconstexpr

Calculate the tick-count between two counter values.

Returns: The value that when added to counter value a would produce counter value b.

Note: a and b are assumed to be 24-bit counter values; if bits are set outside counter_mask the result may be incorrect.

static RTC& nrfcxx::periph::RTC::instance ( int idx )

static

Reference the abstraction instance for a specific peripheral instance.

Parameters

idx	the peripheral instance desired.

Warning: If idx specifies a peripheral instance that does not exist on the device the system will reset into failsafe mode with FailSafeCode::NO_SUCH_PERIPHERAL.
