Constructor & Destructor Documentation

◆ RefOutput()

RefOutput::RefOutput	(	satcat5::cfg::Register	reg_phase,
		satcat5::cfg::Register	reg_period,
		bool	rising = `true`
	)

explicit

Link this driver to the hardware control register.

Parameters

reg_phase	Sets ConfigBus phase-offset register.
reg_period	Sets ConfigBus period register.
rising	Sets the default output polarity.

Member Function Documentation

◆ get_offset()

s64 satcat5::cfg::PpsOutput::get_offset ( ) const

inlineinherited

Query the phase-offset for this output.

Units are subnanoseconds,

See also: satcat5::ptp::Time.

Definition at line 104 of file cfgbus_pps.h.

◆ get_polarity()

bool satcat5::cfg::PpsOutput::get_polarity ( ) const

inlineinherited

Query the polarity of this output.

See also: set_polarity.

Definition at line 113 of file cfgbus_pps.h.

◆ set_frequency()

void RefOutput::set_frequency ( u32 freq_hz )

Adjust the frequency for this output.

e.g., 1 = 1 Hz = 1 pulse-per-second.

Definition at line 141 of file cfgbus_pps.cc.

◆ set_offset()

void PpsOutput::set_offset ( s64 offset )

inherited

Adjust the phase-offset for this output.

Units are subnanoseconds,

See also: satcat5::ptp::Time. Positive offsets increase delay of the synthesized output.
