Welcome


A number of years ago I had finished A Distributed Data Acquisition and Control System which included Sun Microsystems workstations and a number of single-board computers based on the Motorola 68000 microprocessor utilizing the VMEbus.   If I had not stumbled across the the first of Douglas Comer's books on the Xinu operating system, I'm not sure where that project would have gone.  In the end there were as many as four VME system crates each with a master processor running Xinu connected to an ethernet and as many as four slave processors in each crate also running Xinu.

In the last few years I've gotten interested in small microprocessors again and drifted to the Atmel AVR series of processors because of the open GCC support for these chips.  Then I realized that some of the ATmega processors could provide a Xinu platform.  Here we are ...
