Lee, thanks for the reply. Problem is I got the LCD from Greenwelds!! The part data they supply is useless - just a list of part types, physical sizes etc. No pinout info. I'll keep trying the web and if I find anything I'll post back to PICLIST. I bought one of the 2*20 modules for £2.50 and it's a really nice size if I can figure out how to drive it. Thanks, Brian.
