'HC11 please. You wouldn't like translating to an '05.
Oops, you're right, it's the HC16 that's the 16-bit, while the HC11
is the MC6802-compatible instruction set (what the heck was the HK05
then???). Boy, go off the meds for just a little while, look what
Why serial for LCD? You can wire them directly to the address/data bus if
you are running at 1MHz, just pick an unused address to gate
the E clock to the LCD. Or if you want it remote, one 8-bit latch
is all you need. (Assuming you are talking about the 1/2 line
dot-matrix LCDs that are around $10 in just about any electronics
Serial is trivial to think about, and readily implementable (don't have
to worry [much] about "long" wire runs, injecting noise into the bus,
and the like. I'm not opposed to something better.
My current project (after I finish the Duty Cycle and O2 meters) is
an Audi turbo data collection/logging box which will drive such an
LCD... ignition timing, duty cycles, pre/post intercooler temperatures
and G-Tech pro like accelerometer based timings.
