Sorry, Dmitry, but that's so out of touch I don't really know how to
respond so I will just say you don't need a OS to provide I/O services.
You create some routines around the hardware which the rest of your code
can use to talk to the hardware and you structure your I/O support
library so that only the modules needed by the application are actually
linked in.
For the generic I/O support on top of this, you can then use a intermediate
library (in the C world, that could be Newlib for example) or implement the
I/O support in your language (for languages with I/O syntax built in)
or just use your own generic I/O library.
This is the standard approach taken when working with small embedded
systems at bare metal level regardless of language. As Luke said, no
OS needed. How do you think I/O is done on, say, a small AVR or low
end ARM board ?
Simon.
