No.....This example was not a discussion of the best way to handle 8 switches that pulse on 8 LEDs. It is a tutorial on how to write an efficient state machine.

And NO the design of Window's software architecture or other RTOS schemes do not have a place on an 8051 type processor.

It is best, in my opinion, to design the state machine architecture as close to the needs of the problem at hand and not try to pre-dispose the design to the rigors of fancy intellectual concepts and shoe box type software.
