Struct i2c::SmbusReadWrite

pub struct SmbusReadWrite<I>(pub I);

A wrapper around an i2c::ReadWrite that attempts to impl Smbus.

Repeated START is not supported, which may confuse some devices and probably makes this a non-conforming implementation.

Trait Implementations

impl<I: Master> Master for SmbusReadWrite<I>

type Error = I::Error

The error type returned by I2C operations.
