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.....
The link to the OE is: 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.
Also:
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 !!
