Hi,

I have a home-brew programmer that uses a 16F627 to program either
16F877s or 16F872s (or any similar devices)  There is a picture here
http://www.btinternet.com/~Peter.Onion/PIC/DevSys1.jpg

I now want to improve it to handle 18F devices, (initialy just 18F452s).

I'll probably write my own boot load in the end, but to start with I
need to be able to use High Voltage programming.

Does anyone have any 16F series code to program 18F devices that I can
use as a starting point please ?  I've read the programming
specification, and although I understand it, it is much more complex
than the scheme used on the 16F series.  

Peter
