    Hi Andy,

    Well, as you can see it has been a full year since I posted that code.
    I would have to spend several hours studying it to make suggestions that you request.

    Have you tried to load it up and see if you can make it work as is? Just as a starting point?
    As to your question about the R/W pin of the lcd... I was using an LCD with Serial backpack.
    If you don't know what that is take a look here...

    So if you go that route then you will not have to worry about the R/w line.
    They sell just the backpack if you have your own lcd.
    these are VERY handy for prototyping and testing code because they can be written to via a SEROUT command.

    It should work with a regular LCD also just follow the example in the PBP manual as a starting point.

    The real way to learn is to study and try and modify a small portion of the code or the font data table and see what it does.

    My suggestion is that you load the code up in Microcode studio... or even better is the IDE called FineLine as it allows you to visualize the various subroutines and loops very well.

    Give the code a try and then ask questions.

    It is very easy to just copy the code above and past it into your IDE and study it there. Then it will be color coded and easier to read.

    If you havent tried FineLine then give it a try.

    Just search the forum here for FineLine as the author is a regular here and you should be able to find a link to down load it.

    good luck
