Struct Sccb 

pub struct Sccb<I> { /* private fields */ }

A sensor’s control interface over an I²C bus.

Implementations

impl<I: I2c> Sccb<I>

pub fn new(i2c: I, addr: u8, width: RegWidth) -> Self

Talk to the sensor at 7-bit address addr with width register addresses.

pub fn for_sensor(i2c: I, desc: &SensorDesc) -> Self

Talk to the sensor desc describes.

pub fn addr(&self) -> u8

The 7-bit bus address.

pub fn release(self) -> I

Give the bus back.

pub fn write(&mut self, reg: u16, value: u8) -> Result<()>

Write one register.

pub fn write_reg(&mut self, reg: Register) -> Result<()>

Write one Register.

pub fn read(&mut self, reg: u16) -> Result<u8>

Read one register (write the address, then read one byte).

pub fn apply( &mut self, table: &[RegOp], delay_ms: impl FnMut(u16), ) -> Result<usize>

Run a register sequence. delay_ms is called for each RegOp::DelayMs step (the caller owns the clock). Returns the number of registers written.

pub fn probe(&mut self, desc: &SensorDesc) -> Result<bool>

Read the product id and compare with desc.

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

Formats the value using the given formatter.
