Character LCD Displays

[Borisw37]

Hello,
I recently received my EasyPIC2, very pleased with it , thank you.
I would like to add a character LCD display to the board (did not buy one from MikroElektronika). There are a lot of them for sale online, how do i pick one, will any 8/4 bit LCD work with 16f877A? Or does the screen need to have a certain protocol? Or are they all the same?

Thank you,

Boris.

You need to have a LCD that is driven by the Hitachi HD44780 controller (or some clone). The majority of standard character LCDs are compatible with it, and come in many different flavours (2x16, 4x16, 4x20...). Some of them may show strange behaviour when writing to rows >2 (3, 4), so that indexes at LCD_Out() don't match the real thing. This is hard to cope with since there are so many character LCD manufacturers, and many of them are allmost-but-not-fully compatible with each other.

Search through the forum for 'LCD' and you'll find some useful hints there, too.
