public class I2CPermission
extends DevicePermission

The I2CPermission class defines permissions for I2C slave device access.

A I2CPermission permission has a target name and a list of actions.

The target name contains hardware addressing information. The format is the one defined for the base DevicePermission class with the following addition:

{channel-desc}

The {channel-desc} string (described in DevicePermission) is the hexadecimal string representation of a device address on the I2C bus as may be returned by a call to I2CDeviceConfig.getAddress. The characters in the string must all be hexadecimal digits.

The supported actions are open and powermanage as defined in DevicePermission.
