I2C device connection
[sim] = ld_I2CDevice_shObj(sim, events, ObjectIdentifyer, Visibility, I2CDevicename, I2Caddr)
This function creates a shared object for I2C communications
using the linux kernel's I2C-interface. (linux/i2c-dev.h, linux/i2c.h
https://www.kernel.org/doc/Documentation/i2c/dev-interface )
Hardware supporting this interface is e.g. available at the following systems
*) Beaglebone
*) Rasperry Pi
An I2C device at adress I2Caddr ( numbering as used by i2cdetect; Please compare to other notations!)
is opened via the I2C-bus given by I2CDevicename (e.g. "/dev/i2c-0", "/dev/i2c-1", ...)
Currently there are only functions for writing to the bus.
