I need a serial lcd object to replace debug lcd.

I am new to propeller. I just finished my code for my project. and decided because of space limitations i want to use this lcd

instead of the lcd that i made the prototype with.

So the problem is my original lcd had 2 data lines, this one has 4 or 8. I used the commands I found in the debug_lcd object. Now I need a new object to take the place of debug_lcd so I don't have to rewrite my whole code.

What you're proposing to use is not a serial LCD. It's a parallel LCD and it requires a completely different I/O driver. There are several in the ObEx including this one. You will need to do some work to adapt it or one of the others to take the place of the debug_lcd object. It depends on how many and which of the special display functions that you use. Have a look at the various parallel 16 x 2 LCD drivers and see which one(s) fit best with what you're trying to do.

There are several objects for the HD47780 LCD controller (which controls this LCD you are wanting to use).

I have tried several but all require me to change a lot of my code.
