    Keep track of your gosub / return and gotos so you do not get stack overflow or underflows a return should only be approached from a gosub and gosub should always be terminated with return. You should not make word vars unless you actually need them, so as to save memory space. When you post a project, you will make it far easier to debug if you include ALL the code including the setup code, configs and variables. If you do not need IF/THEN/ELSE/ENDIF use a simple IF/THEN
    one liner to save memory.
    18F chips MAY require a programmer upgrade, I found my JDM did not work and had to buy PICKit2.

    Working with the 18Fs is not really any different than the 16Fs.

    The 18Fs have many more options so sometimes the configs are a little more difficult, but the default setup in the PBP *.inc file is good to get started.

    The benefits make running the 18Fs worth it in many cases.

    I think I will go aheah and get started with the 18F series. I will see what happens then programming it.

    I do not find it on Microchips web site either. Do you mean another chip? 2455?
    The 2455 is in PBPs current version, I do not remember when it was added.

    The 16F88 is there. If Micro Code has it then it is in the PBP directory.

    I am not familiar with the INC files. What are they used for ?.
    That is where the configuration bits are set.

    One other thing about the 18Fs. You hace to use MPASM for the assembler. PM will not work.

    Dave,

    Talking about upgrading, do you know if MeLabs is making any plans to include the 24 and 32 PIC series for PBP?
