Hi all !!
I was trying with some 4 lines LCD driver from OE, and I found this, maybe it could be usefull for begginers, to avoid headaches..... http://forums.parallax.com/images/smilies/smile.gif

The link to the OE is: obex.parallax.com/objects/104/ (http://obex.parallax.com/objects/104/)
Name: LCD parallel demo using the Hitachi HD44780 LCD
Version: 1.2

In the code say:

These are the connections I used

PIN 5───────── PIN 4 Enable
PIN 4 ──────── PIN 6 Register Select
PIN 3───────── PIN 11 D4
PIN 2───────── PIN 12 D5
PIN 1───────── PIN 13 D6
PIN 0───────── PIN 14 D7

Be aware !!!

Usually the Enable pin for LCD is pin 6, and Register Select is pin 4.


PIN0 must be D4
PIN1 must be D5
PIN2 must be D6
PIN3 must be D7

Following this, you'l get the driver working nice !!
