Description

This class is an abstact interface for sending data to and receiving data from a I2C device attached to an I2C Bus. If you are using only one device in your application, you should use a derived class, e.g. TI2CLinuxDevice. If there are multiple conccurrent threads in your multi threaded application accessing on bus, you may want to use TI2CBus for request serialization. As an alternative, you should be able to create multiple instances of TI2CDevice---one for each device (not tested). This class is not threadsafe.
