Note to self... while it is perfectly possible to NOT use the R/W pin on an
44780 LCD panel by simply waiting more than long enough for each operation
to complete, you DO still have to ground the R/W pin...

Failure to remember this may cost you hair.... and rather more time that yo=
u
might wish to admit with the logic analyzer attempting to figure out what
you are doing wrong in the code, checking all the /other/ signals, delays,
pouring over the data sheet, checking the code to verify it hasn't been
changed since the last time you used it, etc...=20

/sigh/=20

I have a /really/ nice setup for my ancient HP 1662C for reading 44780 LCD
panel signals if any is interested... and can read 3.5 inch floppy disks.
