=) so far i've coded the core.. =) coded overflow protection etc. what manual are you looking at? can you paste a url? =) thanks man.

a bomb jk.. just a really good interface.. that works @ 19200 bps.. and does a lot of stuff.. like oscilliscope etc.

it's like the programs out there, but will be better. honestly.. those programmers don't know how to give an lcd the looks

oh i just remembered.. cursor on / off?

lastly custom characters?
henry.. i'll write you a nice program..
it uses Perl/Tk =)

cursor moving? :smile: so far i have this:
(note this is perl)

# sub that clears the LCD.
sub clear_lcd { syswrite LH, sprintf ("%c", 12); }

#move the cursor down by a line.
sub cursorbyline_lcd { syswrite LH, sprintf("n"); }

#turn on backlight
sub backlighton_lcd { syswrite LH, sprintf ("%cB%c ...

Alpha Demo's source would be nice.

doesn't matter. paste any bc code..
i just need to look at sample code snippets to figure out.. how to move the cursor around (ie what ascii char's to pass.. to the serial port).

i'm writing a program in perl. i'm having a hard time.. figuring out all the control codes.

ie. to turn on a black light.. you have to do something like
sub backlighton_lcd { syswrite LH, sprintf ("%cB%c", 254, 0); }
where as LH is a filehandle to your serial port. (254 ascii, B(66 ascii), 0 ascii ...
