Enum kernel::hil::i2c::Error

source ·
pub enum Error {
    AddressNak,
    DataNak,
    ArbitrationLost,
    Overrun,
    NotSupported,
    Busy,
}
Expand description

The type of error encountered during I2C communication.

Variants§

§

AddressNak

The slave did not acknowledge the chip address. Most likely the address is incorrect or the slave is not properly connected.

§

DataNak

The data was not acknowledged by the slave.

§

ArbitrationLost

Arbitration lost, meaning the state of the data line does not correspond to the data driven onto it. This can happen, for example, when a higher-priority transmission is in progress by a different master.

§

Overrun

A start condition was received before received data has been read from the receive register.

§

NotSupported

The requested operation wasn’t supported.

§

Busy

The underlying device has another request in progress

Converts this type into the (usually inferred) input type.
source§

impl PartialEq for Error

source§

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

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

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