pub struct Lp55231<I, P> { /* private fields */ }

The LP55231 device

Implementations

impl<E, I, P> Lp55231<I, P>where
    E: Debug,
    I: Write<Error = E> + WriteRead<Error = E>,
    P: OutputPin,

pub fn new(i2c: I, en_pin: Option<P>, addr: Addr) -> Self

Create a new instance of an LP55231 that exclusively owns its I2C bus. Optionally takes a power control pin.

pub fn enable(&mut self) -> Result<(), Error<E>>

Enable the device for use

Sets the enable line high, then sends an enable command, waits 500us, and then configures to device to use its internal clock, enable the charge pump at 1.5x boost, and auto-increment on writes.

pub fn reset(&mut self) -> Result<(), Error<E>>

Soft-reset the device NOW

pub fn disable(&mut self)

Turn off the device NOW

pub fn set_pwm(&mut self, d: D, pwm: u8) -> Result<(), Error<E>>

Set the D line to the provided PWM value
