Big LCD compatible with Stamp 2

Josh Foure

Hi all, I've gotten the 2x16 Parallax LCD to work with my Stamp 2 but I am now looking for a much bigger LCD. Ideally I would like to be able to display at least 2 rows of characters in font that is about twice as big as the font in the 2x16. A 4x40 LCD would be about as small as I want but I haven't found one where you can increase the font size where 1 character would be 2x2. So I have been looking at graphical LCDs. I stumbled up the GLK24064-25-GW from Matrix Orbital (http://www.matrixorbital.com/glk2406425gw-p-278.html) which is 132mm x 39mm. Does anyone have any experience with these? Based on the manual it looks like it will work with 5V and support RS-232. Can anyone validate that this will work or point me to another one of similar (or bigger) size?

Thanks!
Josh

Not exactly sure what you lloking for but Scott Edwards sells a 4x20 that supports "big character mode" in this serial LCD and it works great with the Basic Stamp...

Thanks ronczap. The issue is that I would want at least 2 lines of text and would want to do about 20 characters per line. The 4x20 LCDs I have found appear to be able display 1x1 characters to get a 4x20 display or 4x4 characters to get a 1x5 of large character displays. I haven't seen an LCD capable of displaying 2x2 characters which would give a 2x20 display of these medium sized characters. For my purposes I think the Matrix Orbital would work and it is fairly big. I was wondering if someone else could validate this. I saw from another post (http://forums.parallax.com/forums/default.aspx?f=5&m=367907) that a similar screen from the same manufacturer does work. But it would be great if others would post their experience with big LCDs as well so I could make an informed decision.
