  Hey. I donno about how to go about it, but all I would first do is do a research in display driving technics and how to interface it with a PIC to display the message.
  about righting the program for the PIC, well I'm also learning it, it's a bit too early for me to teach it.
  My next option will be to google all info and read and read, it always helped.
  Cheers

  If you are using Character LCD, you must know how to configure that LCD first. Then, you coding your FPGA.
  Normally it's fast learn through the example. I'm sure many example in PIC. For FPGA, I have ever done. It's more complicated to control the timing.

  hey guys....thanks for the replies but it was not what i was looking for. maybe i was not articulate enough with my first post. i am using the actel proasic3 fpga and i want to display three various words on the lcd of the fpga when switches are pressed. For example 1. sw1 pressed - lcd displays "cat"
  2. sw2 pressed -lcd displays "dog
  3. sw 3 pressed -lcd displays "monkey"
  
  i need to implement this using vhdl and really soon.......anyone who can help???
  
  thanks 😀

  i know that i should design a state machine, use a multiplexer. But what else and how do i interconnect them?HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  The connection is simple, just direct connection. Your VHDL depends on your skills. You may need design a timer also to control the LCD timing. See this ex. fpga4fun.com - Text LCD module
