NPL decoder class

Implementations

impl NPLUtils

pub fn new() -> Self

pub fn get_first_minute(&self) -> bool

Return if this is the first minute that is decoded.

pub fn get_new_minute(&self) -> bool

Return if a new minute has arrived.

pub fn force_new_minute(&mut self)

Force the arrival of a new minute.

This could be useful when reading from a log file.

This method must be called before increase_second()

pub fn get_new_second(&self) -> bool

Return if a new second has arrived.

pub fn get_second(&self) -> u8

Get the second counter.

pub fn get_current_bit_a(&self) -> Option<bool>

Get the value of the current A bit.

pub fn get_current_bit_b(&self) -> Option<bool>

Get the value of the current B bit.

pub fn set_current_bit_a(&mut self, value: Option<bool>)

Set the value of the current A bit and clear the flag indicating arrival of a new minute.

This could be useful when reading from a log file.

This method must be called before increase_second().

Arguments

• value - the value to set the current bit to

pub fn set_current_bit_b(&mut self, value: Option<bool>)

Set the value of the current B bit and clear the flag indicating arrival of a new minute.

This could be useful when reading from a log file.

This method must be called before increase_second().

Arguments

• value - the value to set the current bit to

pub fn get_radio_datetime(&self) -> RadioDateTimeUtils

Get a copy of the date/time structure.

pub fn get_parity_1(&self) -> Option<bool>

Get the year parity bit, Some(true) means OK.

pub fn get_parity_2(&self) -> Option<bool>

Get the month/day parity bit, Some(true) means OK.

pub fn get_parity_3(&self) -> Option<bool>

Get the weekday parity bit, Some(true) means OK.

pub fn get_parity_4(&self) -> Option<bool>

Get the hour/minute parity bit, Some(true) means OK.

pub fn get_dut1(&self) -> Option<i8>

Get the value of DUT1 (UT1 - UTC) in deci-seconds.

pub fn get_spike_limit(&self) -> u32

Return the current spike limit in microseconds.

pub fn set_spike_limit(&mut self, value: u32)

Set the new spike limit in microseconds, [0(off)..ACTIVE_0_LIMIT)

Arguments

• value - the value to set the spike limit to.

pub fn handle_new_edge(&mut self, is_low_edge: bool, t: u32)

Determine the bit value if a new edge is received. indicates reception errors, and checks if a new minute has started.

This function can deal with spikes, which are arbitrarily set to spike_limit microseconds.

This method must be called before increase_second().

Arguments

• is_low_edge - indicates that the edge has gone from high to low (as opposed to low-to-high).
• t - time stamp of the received edge, in microseconds

pub fn get_minute_length(&self) -> u8

Determine the length of this minute in seconds.

pub fn end_of_minute_marker_present(&self, look_ahead: bool) -> bool

Return if the end-of-minute marker (0111_1110) is present at the end of the A bits.

This method must be called before increase_second()

Arguments

• look_ahead - look ahead one second to check for a positive leap second

pub fn increase_second(&mut self)

Increase or reset second and clear first_minute when appropriate.

This method must be called after decode_time(), handle_new_edge(), set_current_bit_a(), set_current_bit_b(), end_of_minute_marker_present() and force_new_minute().

pub fn decode_time(&mut self)

Decode the time broadcast during the last minute.

This method must be called before increase_second()

Trait Implementations

impl Default for NPLUtils

fn default() -> Self

Returns the “default value” for a type.
