Hi,it maybe sound like a dumb question,is any PIC with f2f decoder built in on the market?

NAFAIK. F2F calls for ASICs or specific code(=$$$), & it's complicated by varying card read speeds.

With hindsight, manuka seems to have had the key; "complicated by varying card read speeds". F2F seems to be the encoding mechanism used on plastic card magnetic stripes. I hadn't twigged which "cards" manuka was talking about.

So, the answer to the original question seems to be, "The Microchip site is the best place to check".

F2F or Delta ASIC means that decode the data from analog to digital,or in this case from a wave to data(dont know exactly how to explain) just google Delta ASIC and you will find there the explanation

can you be moore specific please?have a link of this?

It is not clear what information you are after. With respect to whether any PICmicro's support F2F ( your original question ) then Microchip would be the best place to ask and look. None of the PICAXE support F2F per se.

If you are just after further information on F2F, Google or your favourite search engine would be the best way to research and find the information and links you require. Many companies supply ready built hardware for F2F decoding and it can be supported using microprocessors, for example -

It appears F2F or Aiken Biphase is quite a simple protocol and should be fairly easy to implement -

The real question is, what is your real question ?

My real question is if you can implement the F2F decoding into a PIC or if its any PIC on the market witch has F2F decoder built in.Simple as it is.Thanks

As this forum is for the Rev Ed range of PICAXE devices using the BASIC programming language you may do better to ask your question on the MIcrochip forum as Microchip are the manufacturs of the PIC chips.
Then again there may be a PIC guru or three here ;)
