LCD - 4x20 display
Archiver
Posts: 46,084
Hi:
I am using a 4 x 20 LCD idplay with a BS2P stamp. The manual covers use of 1
and 2 line displays, but not 4 line, except to mention that scrolling won't
work.
Has anyone used a 4x20, and if so, can they provide the necessary overhead
software to make it work?
Thank you,
George

for multiple lines. The reason scrolling doesn't work with these displays is
that physical line one wraps to phsyical line three. So ... don't try to
scroll mutli-line displays.
These are the constants I use for locating the cursor to a specific line:
Line1 CON $00
Line2 CON $40
Line3 CON $14
Line4 CON $54

specific to the 4x20 display, but with the information you have now, it will
be enough to get you going. Take a look at the BS2p "Plus Pack" page.

It's easier than you'd think. I've managed to control a 2 x 20 display on a
BS2 which doesn't even have the LCD commands built in. A 4 x 20 shouldn't
be too much more effort. The 2 x 16's are easy to get in NZ via Dick Smith
Electronics, but I'm not too sure where to get the other versions.
The 2 x 20 was given to me by a guy who works at Captron in Auckland, so
they may supply the other versions. Any Auckland Stampers on the list who
could check for me?
Cheers,
Ben, Wellington, New Zealand.
