In the FAQ, there is a section on serial communication with pics.

Step 1 is getting communication between 2 chips.
Step 2 is easy too.
With communication established, you can use SERin and SERout to control which chips receive what. The "Code" string can be 2 charactors chosen specifically for a certain chip. and the data following the code string is your info being sent to the chip.

So lets start with Step 1 ok? Have you got communication between two chips? Where one will send data, and the other will put the data on a LCD? If you do not have this communication between two chips, you are wasting your time.
