[−][src]Enum rppal::i2c::Error

pub enum Error {
    Io(Error),
    InvalidSlaveAddress(u16),
    FeatureNotSupported,
    UnknownModel,
}

Errors that can occur when accessing the I2C peripheral.

Variants

Io(Error)

I/O error.

InvalidSlaveAddress(u16)

Invalid slave address.

I2C supports 7-bit and 10-bit addresses. Several 7-bit addresses are reserved, and can't be used as slave addresses. A list of those reserved addresses can be found here.

FeatureNotSupported

I2C/SMBus feature not supported.

The underlying drivers don't support the selected I2C feature or SMBus protocol.

UnknownModel

Unknown model.

The Raspberry Pi model or SoC can't be identified. Support for new models is usually added shortly after they are officially announced and available to the public. Make sure you're using the latest release of RPPAL.

You may also encounter this error if your Linux distribution doesn't provide any of the common user-accessible system files that are used to identify the model and SoC.
