First time using an LCD (Jameco/Ampire 2x16 unit), and just
experimenting a bit for now.  If you're curious, datasheet
is at: https://www.jameco.com/Jameco/Products/ProdDS/171715.pdf

I'm controlling the LCD manually (for now) with 11 DIP switches.
Sounds painful I know, but it's not that bad... if it works.
Which it doesn't exactly.

For each bit-combo. I setup the bits with enable set LOW, then
toggle enable to HIGH and back to LOW.  First I ran though the
initialization sequence this way, then set DDRAM to address 0,
then wrote data LLHHLLHH to the RAM.  What I get is the char
'3' display, but on the first 6 character positions.  If I
toggle the enable to HIGH and back to LOW again, it writes '3'
in the next 6 or so positions.

That's odd.  Anyone know why?  My guess is that I'm missing
something fundamental on the operation of LCD's, and the
datasheet is not exactly as well detailed as, say, a Microchip
datasheet.

Another Q... I guess CG stands for character generator, but
why is there an operation to write to CG RAM?  What's the
purpose of that?  Can I create my own fonts or something?

Thanks,
-Neil.
