Description

This class implements the access to a single I2C device using Linux' file system interface.

Please check you have loaded the Kernel module i2c-dev before creating an instance of this class. This module creates the /dev/i2c-* files, which are used by user space programms (like yours). You may need to load another kernel module, for making the I2C busses accessible by the kernel itself.
