Found one of these 2 line by 16 character LCD displays in my junk box. On a whim, I thought to hook it to a chip and display some gibberish.
I find a PDF with descriptions of the 15 pins and timing diagrams, but no command information. Seems to me these had commands to move to a position, write a string...
Anybody know where to find a description? I'm not above trying to use a library. Maybe there's one in the toolchain? This module has the 15 pins,
4. Register Select
I see it has a 4 bit and an 8 bit mode. My stupid idea only needs a couple other IOs, so I figured on using PB0-7 for the display, some others for Register Select, Read/Write and Enable.
(No, it's not for the Shakespearean insult program, though that does sound fun.)
