Add ISO14443B support

[zhongfu]

These changes allows users to detect, inList and exchange data with ISO14443B cards.

This commit has only been tested with ISO14443B cards (e.g. Singapore CEPAS standard cards) and SPI with an ESP8266 -- more testing may be required to ensure it doesn't break anything with other cards or protocols.

(As a unrelated sidenote, in case you're planning to test this with a CEPAS card: on certain modules, the antennas may not be able to read CEPAS standard cards. I've had success with a larger module with a rectangular (not square) antenna though. YMMV.)

Hello, I tried your branch, as I need to read some type b tags (VaultIC 154). But I always have "Timed out waiting for a card" in loop. I use the adafruit PN532 in SPI mode. Any idea ?

Thanks in advance!

Hi I am currently facing the same issue. "Timed out ..."

My first check : the chip Seems like pn532 does accept 14443B mode whereas pn522 does not. Both readers have a pn532 chip, so this is not an issue with the chip.

Next check : library Using libnfc. Investigated through the libnfc c files and searched for the term "14443B". Mentioned so many times that it can be inferred 14443B is being supported.

Google https://github.com/nfc-tools/libnfc/issues/397 I quote neomilium "Some hardware are not able to communicate with ISO14443B tags due to antenna or amplifier. In this case, there is no way to fix it using software, sorry." It turns out Neomilium is a libnfc author.

So, it looks like an antenna issue. I've just ordered another bunch of readers to be tested. I'll share the results.

Would be really nice if this would get merged

Hello gentlemen,

i am very interested in reading iso14443b cards, i have a box full of them the i purchased. I recently bought the PN532 cause according to the specification when i bought, that it can read iso14443b cards. i look everywhere and i came across this github link and it brought some hope after so much time searching.

Anyways I visited this https://github.com/nfc-tools/libnfc/issues/397, and tried the code that is there, i played with it but i couldn't never find the nfc/nfc.h library anywhere.... any hopes or ideas?

[asdfjkl]

It did extensive testing with the shield and ISO 14443 B cards, and thorougly studied the NXP chip documentation of the PN532. Some Type B cards worked, some didn't. I had success with some Japanese passports. Lot's of European ID cards and some non-NXP JavaCards did not work.

These cards simply didn't show up in the field at all. This means that either these cards require some obscure combination of RF settings (I could not find an RF setting of the PN532 that worked) or that the antenna design is not suited to reliably working with Type B cards.

In other words: If you rely on Type B cards working I recommend to look for other solutions than the Adafruit shield. Type A works fine (even though no extended length support). I therefore think this pull request should not be merged, as users might falsely think that they can get any Type B card working.
