The i2c interface
i2c provides access to a specific I2C controller. This interface is restricted because it provides privileged access to hardware devices.
path(slot): path to i2c device node e.g.
To use a i2c device, the snap developer must add
plugs: [ i2c ] to a snap’s snapcraft.yaml. The snap user can then access a specific i2c device with an interface connection.
snap interface i2c to see which i2c devices are available on the system:
$ snap interface i2c name: i2c summary: allows access to specific I2C controller slots: - pi:i2c-0 - pi:i2c-1 - pi:i2c-2
Once connected, the consuming snap can use the device via the path specified by the connected slot.
This is a snap interface. See Interface management and Supported interfaces for further details on how interfaces are used.
