MraaI2c class

The I2C MRAA API

An I2C context represents a master on an iI2C bus and that context can communicate to multiple I2C slaves by configuring the address. It is considered best practice to make sure the address is correct before doing any calls on I2C, in case another application changed the address on that bus. Multiple instances of the same bus can exist.
