any one happen to have a pic16f688 bootloader? i'm building my programmer this week (and i will be releasing it and it's code on the pic site etc., after writing said code also hopefully this week), but it would be nice to be able to have users able to upgrade later (i may eventually make a little money, it's a clock chipping toy, i'll put a link in my sig line when it works, more advanced chipping may follow). i'll be using said chip because of it's size. i don't think i'll have trouble writing code for what i need to do, but if someone already has a bootloader working i can avoid worrying about that part. if no one has one i'll try writing one and if it works i'll definitely make it available (though i'm not letting out the rest of my design right away, i'd really like to at least make back my startup cost for things like the programer, having boards made, etc.), though if i break even and make enough money for my next project i'll more than likely release the whole thing (besides, the board is so crowded you really wouldn't want to try and copy it, 6 hours for 27 connections with 3 chips! and i've done layout before, it's just very, very crowded for 2 layers). any help would obviously be appreciated, and would probably mean i owed you a favor or at least a large discount (labor i can give away, parts i usually can't). thanks in advance either way, and like i said if i have to bang one out myself i'll definitely post it. oh, and by bootloader, in this case i mean something that can update the code through the built in serial port that will be connected to the users machine (i'll probably have to write a little code for the computer end as well unless i use a common exchange format like kermit or whatever which i'm not terribly familiar with yet, not in the details at least). on the other hand, a bootloader for any format/interface would be a good start. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
