Attiny2313 and LCD example

This is a very similar example to our ATMEGA16 and LCD example. We simply connect our 16×2 LCD display to our Attiny2313 PORTB. Again for simplicity the code is written in MikroC PRO for AVR.

We actually added and LCD breakout to our Attiny2313 development/experimenting board
