Hi mackrackit

The program worked a treat, many thanks for your time and input on this. I saved the HEX code as Blink.HEX just added .HEX to the end (Doh) and it loaded into the PICKIT1 and then loaded into the PIC and away it ran:

D0 - D1 - D2 flashing one after the other, brilliant!

I noticed you wrote the program for the 16F676 PIC yet it ran perfectly on my 12F675 chip, very clever but how does that work? I guess both chips have certain ports and configurations that are common.

Would it have been possible to have copied the program you wrote and pasted that directly into Microcode Studio - demo and created the HEX file that way? I would like to do this if it can be done to get a feel for converting program code to a HEX file.
