Struct Configuration 

pub struct Configuration {
    pub high_alert: bool,
    pub low_alert: bool,
    pub data_ready: bool,
    pub eeprom_busy: bool,
    pub mode: ConversionMode,
    pub cycle: ConversionCycle,
    pub averaging: Averaging,
    pub alert_mode: AlertMode,
    pub alert_polarity: AlertPolarity,
    pub alert_pin: AlertPin,
    pub soft_reset: bool,
}

A decoded TMP117 configuration register.

Build one, set the fields, and turn it into the 16-bit register value with bits; or parse a register read with from_bits. Configuration::default is the factory state, 0x0220. The four flags are read-only on the device and are ignored when written; soft_reset triggers a 2 ms reset when written and always reads back clear.

Examples

use pamoja_sensors::tmp117::{Averaging, Configuration, ConversionCycle};

// Average 32 conversions every 4 s, leaving everything else at the factory default.
let config = Configuration {
    cycle: ConversionCycle::S4,
    averaging: Averaging::X32,
    ..Configuration::default()
};
// The high byte then the low byte are written to the configuration register.
let [hi, lo] = config.bits().to_be_bytes();
assert_eq!(Configuration::from_bits(u16::from_be_bytes([hi, lo])), config);
assert_eq!(config.cycle.cycle_micros(config.averaging), 4_000_000);

Fields

high_alert: bool

HIGH_Alert flag (bit 15), read-only.

low_alert: bool

LOW_Alert flag (bit 14), read-only.

data_ready: bool

Data_Ready flag (bit 13), read-only.

eeprom_busy: bool

EEPROM_Busy flag (bit 12), read-only.

mode: ConversionMode

The conversion mode.

cycle: ConversionCycle

The continuous-mode conversion cycle.

averaging: Averaging

The number of conversions averaged per result.

alert_mode: AlertMode

Whether the limits act as alerts or as a therm hysteresis band.

alert_polarity: AlertPolarity

The ALERT pin’s active level.

alert_pin: AlertPin

What the ALERT pin reflects.

soft_reset: bool

Soft_Reset (bit 1): set to trigger a software reset when written.

Implementations

impl Configuration

pub fn bits(self) -> u16

Assembles the 16-bit configuration register value.

Returns

The register value to write, most significant byte first on the bus.

pub fn from_bits(bits: u16) -> Configuration

Parses a 16-bit configuration register value.

Arguments

• bits - the register value, as read from the device.

Returns

The decoded configuration.

Trait Implementations

impl Clone for Configuration

fn clone(&self) -> Configuration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Configuration

impl Debug for Configuration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Configuration

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Configuration

impl PartialEq for Configuration

fn eq(&self, other: &Configuration) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
