2 Line Chars on a 2 Line LCD

[Squibcakes]

Hey Everyone,

Is it possible to display double sized Characters on a 2 line LCD display?

Not directly. but it does allow you to create custom charachters (only eight, IIRC) then you could piece them together to make your own chars.

I seen sombody advertising a 4 line LCD that made tall letters this way. (seetron, I think)

Some Alphanumeric LCD's using the Hitachi HD44780 chip allow you to switch into a 5 x 10 character set from the usual 5 x 8. This however stops you using Line 2 of the two line display.

There are just so many variants of this LCD in existance, it's almost impossible to know if your one would work that way without referring back to your devices manufacturer.

An additional problem here is that the Font selection is performed as part of the Function Set byte which is also used to define the Data Set length and the number of Display Lines. This is done behind the scenes by PBP's LCD routines which is not easily got-attable within your code. Once set, you can't change it without a reboot first, as the Function Set byte has to be amongst the very first bytes sent to initialise the LCD - again, done behind the scenes for you by PBP, so you never have to worry about it.
