    I got a 16x2 lcd display that comes with 16 pins. So I would like to try interfacing with my Rx circuit such that when there is a transmission, the lcd would display a message or something. I use HT12E and HT12D for the Tx-Rx circuit.
    My idea is to wire up the 'E' pin of lcd to the Rx data i/p. Then the rest of D0-D7, R/W and Rs, I will connect to my PIC18F4520 port for programming.
    I am unsure of this. Did I missed something else or my idea seems wrong? Anyone can kindly guide me?

    You should check your compiler for integrated LCD support. MANY compilers have built in support for 7seg LED, GLCD, and LCD displays. It can be as easy as using a type of 'print' command.

    As for attaching the display to the PIC, you should check the datasheet of the display and you can do a google search with the LCD driver type and your PIC type to see if there are folks that have posted the proper way to attach the two and get the communications done.
