Attribute List

current_slave: Optional attribute; read/write access; type: Object or Nil.
The slave of the currently ongoing transaction, if any.

current_state: Optional attribute; read/write access; type: unknown type.

i2c_device_state: Optional attribute; read/write access; type: [iiii].
List representing data state in the device

i2c_devices: Pseudo attribute; read-only access; type: [[si]*].
Contains a list of the devices connected to the bus. Each list entry is a list of (device, address) for each address that has a device connected. Devices connect themselves using the i2c-bus interface.

sda_target: Optional attribute; read/write access; type: n|o|[os].
Describes where the outgoing SDA signal should be connected
