Convert code 12C508 to 12F508

[Olivier]

Hello,

I am new in the forum, My name is Olivier, and I like electronic and my passion of electric trail, scale HO (1/87).
I hope somebody can help me about PIC 12F508.
I have a file XXX.asm and XXX.hex for a PIC 12C508, It's a program for "Decoder for Locomotive"(see attachement files)
but this PIC is obselete now, and I Would like use a PIC 12F508.
I would like to know how I can do for convert my file XXX.asm or XXX.hex for use with my PIC 12F508?
I am new on program PIC, I have a programmer PIC and MPLAB

In advance thanks you

Olivier

This should be 100% compatible with your code. Well, at least 99%.

I did notice that it would not compile with my mpasm. They use a variable called CONFIG, and this is in the first column. Mpasm does not like this. So I renamed it SETTINGS, and it compiles fine. Should operate fine too, but you will have to check that out.

        LIST	P=12F508             ; target processor
        #include	"P12F508.INC"        ; include Header file

	__CONFIG	_CP_OFF & _WDT_OFF & _MCLRE_OFF & _IntRC_OSC
