Struct Reading 

pub struct Reading { /* private fields */ }

One result register word, with the conversion to illuminance.

Examples

use pamoja_sensors::opt3001::Reading;

// Exponent 0 over mantissa 3200: 0.01 lux per count, 32 lux.
let reading = Reading::new(0x0C80);
assert_eq!(reading.milli_lux(), 32_000);
assert_eq!(u16::from_be_bytes(reading.to_bytes()), 0x0C80, "high byte first");

Implementations

impl Reading

pub fn new(raw: u16) -> Reading

Wraps a result register word.

Arguments

• raw - the word: a four-bit exponent over a twelve-bit mantissa.

Returns

The reading.

pub fn raw(&self) -> u16

Returns the register word.

pub fn milli_lux(&self) -> u32

Returns the illuminance in millilux, exact in integer arithmetic.

pub fn lux(&self) -> f32

Returns the illuminance in lux.

pub fn to_bytes(&self) -> [u8; 2]

Returns the register bytes, most significant first, as the part sends them.
