The *concepts*/design are what you are trying to reuse, not
the *code*.

OTOH, we see increasing numbers of designs migrating into
software that would previously have been done with hardware
as the costs of processors falls and capabilities rise.
This makes it economical to leverage the higher levels of
integration available in an MCU over that of "discretes"
or, worse, a *specific* "custom".

E.g., I can design an electronic tape rule in hardware or
software in roughly the same amount of effort.  But, the software
version will be more mutable, in the long term, and leverage
a single "raw part number" (the unprogrammed MCU) in the MRP
system.

OToOH, we are seeing levels of complexity now -- even in SoC's -- that
make "big" projects much more commonplace.  I'd hate to have to
recode a cell-phone for a different choice of processor if I'd not
made plans for that contingency in the first place!
