Hi there! >:04400E00F93F010075 So I just have to put that line in the beginning of my hex file right? Is it like that for all the other programmers? >I'm working on a EXE file that will make this change for you/me and when I >get it done, I'll send you a copy if you want. I don't want to get >overwhelmed with requests for copies so if someone has a site where it >could be accessed, let me know and I'll send it to them when I get it done. Great then! Thanks a lot! By the way, anyone can explain to me what is a fuse? Im just starting to learn PIC programming so I don`t know much... Did someone ever tried programming a PIC16C84 using the electronic shematic in Microchip`s application notes? What are the results? Talk to you soon, Jean-Francois ----------- Jean-Francois & Alain Joly jolyal@capitalnet.com
