[sdiy] 4-bit encoder?

"Counterpoint: a Cortex M0+ offers a whole lot more horsepower in the same
form factor for the same or lower cost, yes - but the overhead of all that
complexity can be fairly substantial in terms of development effort. Getting
from "power-on" to "peripherals initialized" to "application running" on the
8051 or Z80 is simplicity itself; doing so on a modern processor with an MMU
and dozens of integrated peripherals, not so much. (And sure, sometimes your
development environment will have library functionality to take care of that
for you, but not always, if the number of tutorials I see on a quick search
is any indication.) There's plenty of merits to newer hardware, but when all
you really *need* is a lawnmower engine, why go to the trouble of trying to
mount a top-of-the-line fuel-injected turbocharged V12 with a CVT?"

See what I mean?  To me, one minute spent learning why the Cortex MO+ is
better than the Omnicorp BR-549 is just another minute of my life gone.  I'm
very happy that there are people who do make it their business to know such
things, and that they design and make products that I might want or need.
