About this Code Example
In this code example, XLCD library support for PIC18F4685 is used to interface the device with LCD module
available on PICDEM2+ board. The software implementation makes use of the following connections described below.
HARDWARE CONNECTION DETAILS:
**DATA_PORT defines the port to which the LCD data lines are connected */
DATA_PORT <--------> PORTD
TRIS_DATA_PORT <--------> TRISD
* CTRL_PORT defines the port where the control lines are connected.
* These are just samples, change to match your application.
RW_PIN <--------> PORTA<2> /* PORT for RW */
RS_PIN <--------> PORTA<3> /* PORT for RS */
E_PIN <--------> PORTA<1> /* PORT for D */
