Figuring out the FUSES is half the battle...

Posted: Wed Jul 20, 2011 1:57 pm

Hi Everyone -

I've spent a good deal of time trying to get some explanations as to the various fuses that I have seen listed in the codes that are provided in this forum. In searching for other things (that I will post soon enough), I found the "Rosetta Stone" of the fuses in the PICC directory. It would have been GREAT if this had been in the Manual.

C:\Program Files\PICC

Code:

ABW20 20-bit Address bus
ABW16 16-bit Address bus
ABW12 12-bit Address bus
ABW8 8-bit Address bus
BANDGAPLOW Lowest Bandgap voltage
BANDGAPHIGH Highest Bandgap voltage

Yeesh...it was a lot simpler 25 years ago.......seems there's more fuse options than processor instructions !!

One thing I ran into the other day (compiler 4.116?) was with the wizard (which I believe was dropped on his head at some point ... ). Did a quick new project for a 16F1827 and got a bunch of compile errors. In looking at it, the header file it had generated had put multiple fuse definitions on one line in several cases - not in the legal format, but combined two lines: #FUSE fuse1 #FUSE fuse2 When I split those up into separate lines, all was well. Just a bit of warning to others if they run into this situation (the wizard has a strange sense of humor) mikey _________________ mikey -- you can't have too many gadgets or too much disk space ! old engineering saying: 1+1 = 3 for sufficiently large values of 1 or small values of 3
