There are at least six different Microchip boards that start with "PICDEM".
What's the full name of your board ?

This is a drawing of the LCD.

It has 4 "commons" and 10 segment lines. The pin connections
are listed on page 6.

The ASM code in the Microchip LCD driver file would have to be
translated to use the CCS LCD functions. Here's one post where
I tried to help someone figure out the CCS example file, Ex_LCD92.c:

The 16F917.h file lists the constants that can be used with the setup_lcd()
function. Since your LCD has 4 "commons", you would use the
LCD_MUX14 constant in setup_lcd().

If you're new to C and electronics and LCDs, this is not going to be easy.
