I have a pn 532 reader breadboard system working.
For cost reasons i would like to use pn522 based boards but the libraries are nowhere near as good for the ones for pn 532.
I have about a year or so experience with arduino and c++.
I have kelley and pohl book on c which has sparse library examples.
I have about 6 months to get up to speed.
Is this a realistic idea please .

That depends. If you are going to ask questions. Put a "?" at the end of your question. I don't know what country you are from but I thought that was an internationally understood concept.
What is your expectation as to what you should be able to do in six months ?????

This means nothing to us. If you are going to ask us questions about things, post the datasheet or a vendor link to the product or device you are asking questions about. If you were asking about an arduino I wouldn't be saying this . This is an arduino forum. Is a pn532 or pn522 an arduino product ?
pn522 DATASHEET ?????
The Adafruit NFC shield uses the PN532 chip-set (the most popular NFC chip on the market) and is what is embedded in pretty much every phone or device that does NFC
Wouldn't using the pn522 defeat the whole purpose of your project if everything uses pn532 ?
The question is given my programming experience is it practical for me to consider rewriting libraries.
I realise that is a bit of a difficult question to answer
I have a habit of jumping in at the deep end but i cannot afford to waste 6 months with no result.
Cost advantage of the 522 outweighs the popularity of the 532.
Additional information.
For £3 everyone in the class can have reader, for £15 they cannot.
There is some educational kit out there which they have a sample of.
Disapoitingly the reader writer has defied all attempts at writing data.
From reading a couple of posts on here and the web i think this is probably something being used in schools.
It may be that i will have to dispense with nfc and settle for reading writing native mifare cards for this application.
I don't think anyone here can answer the question about rewriting the libraries until you can prove that the pn522 can be made to work. Until you have proof that it can be read by an arduino any discussion about rewriting libraries would be a waste of time, because you don't know the extend of the changes necessary. To answer the question of whether or not the pn522 can be made to work we would need a datasheet and so far you have not produced one and I can't find one on the web. Until you can produce a datasheet for the device you want to use there is no point in any further posts on this subject. If you had the datasheet, I can't think of a reason why you couldn't get it to work. The question you should be asking yourself is why are you asking us questions that are irrelevant and impossible to answer without the datasheet ?
