How to program a PIC16F877a or PIC18F452?

1. How to program a PIC16F877a or PIC18F452 :

The method is analog as for a PIC16F84.

2. Which programmer to use :

Also with a PIC16F877a or PIC18F452 you need a programmer to write a program with picprog to the PIC. I have made a little adapter-print, so that I can use my old PIC16F84-programmer to write a program to a PIC16F877a or PIC18F452.

2.1. My old PIC16F84-programmer build into a little box.

2.2. The adapter-print.

Not very beautiful... I know, but it does the job ;-)
BTW, the ZIF-socket that you can see on this pictures is a gift from Jan Verhoeven at IWM2003.

2.3. My old PIC16F84-programmer with the adapter-print.

3. Tip : --erase :

Try to use the option --erase with picprog when writing a hex-file to the PIC16F877a or PIC18F452 doesn't seem to work.
