Title: LCD Questions
Post by: spizzak on July 13, 2009, 10:13:04 AM

Hey everyone, I'd like to do some experimenting with some LCD displays. Could anyone suggest a good one (easy to use, and inexpensive) that I can start with. (I'd like to control it with the ATmega8)

Thanks!

I would go for one of SparkFun's serLCD's... although it will use up one of your uarts, but if that isnt a problem, it saves on all the I/O pins you would be using otherwise ;)

1 line, 24 character LCD for $1.85

The pin spacing is a bit close - it doesn't plug into a solderless breadboard. But otherwise these are great little character-based LCD displays.

Also there's my library for outputting chars, with source code.

The sparkfun serial LCDs won't need any tinkering, all you do is rprintf to them and they just work. If you want to experiment a bit get a standard HD44780 driver-based LCD. Those are the most common types used in hobbiests, and there are plenty of libraries to use.
