c508 to f84?? | Piclist | EmbeddedRelated.com

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

Yes, The GPIO pins on the C508 correspond to PORTB on the F84. Just use PORTB.0 thru PORTB.5 remembering that GPIO3 (IIRC) is an input only. This equates to PORTB.3. Regarding ocsillators, the F84 doesn't have the RC oscillator that doesnt need any external components. You'll have to use an external RC on the F84, but that shouldn't be a big problem. If it were me, I'd just use a canned oscillator to run the F84. I use the canned oscillators all the time. And finally, don't use anything on the F84 that isn't included on the 508, and you should be okay. And as a last note, you may want to consider the F67X series. They are pin compatible with the 508 (again IIRK), and they have flash memory, so you don't need an eraser. Hope this helps.

Hi List.
Any idea how to convert a program for 12c508 to 16f84 and back, in order to use the re-programmable 16f84 to fix an OTP 508 ?

I believe that's the 12F629/12F675 which are pin-compatible with the 12C509/12C509. More memory too. --- In , "Paul James E." <jamesp@i...> wrote: > > Yes, > > The GPIO pins on the C508 correspond to PORTB on the F84. > Just use PORTB.0 thru PORTB.5 remembering that GPIO3 (IIRC) > is an input only.
