Hello,

I developed an NFC library that supports .Net Micro Framework 4.2 and 4.3 (and other frameworks).

For now, it supports NXP PN532 chip with all possible communication channels (I2C, SPI and HSU).

You can find it at following links on CodePlex and Code Gallery :

I hope it could be useful !!

Paolo.

Hi Paolo!!

Great job!!! I�ve been working on this also some time ago. But I came across with a problema when I tried to communicate a Netduino2+ Adafruit NFC shield(PN532 chip) and a Windows phone..........Have you done any kind of test in something similar to this????

I testd the library with Netduino Plus (first generation) but I will test it also with Netduino Plus 2 (you can start to test if you want :-))

I used following breakout board :

I can't run this library on netduino plus, because netduino uses microframework 4.1 and library needs 4.2. Is there any way to solve this problem?

Hi vz10, I'm pretty sure that the library can work on 4.1 too. For this, create a new 4.1 project and import the cs files shared by Paolo.

Hope that you will succeed.

I've already tried it, but I've got a lot of errors like "unknown name in this namespace", which didn't appear when I triedit in 4.2 version.

Hi all,

excuse but I'm very busy with my other open source projects...for example M2Mqtt :-)

However ...

Hi vz10 can you share more details about "unknown name in this namespace" errors you have ?

Thanks,

Paolo.

Hi Paolo,

Thanks for doing the hard yards.

I have got the following NFC board http://www.aliexpres...2038722238.html

Have configured it to use I2C, but not having any luck communicating with it.

Using 2.2KOhm pull up resistors and have tried both 3.3V and 5V.

The Execute in I2CWrite fails with write = 0

Any idea on what it could be?

PN532 is a specific chip from one company only, right?

I have an I2c lux meter and that works fine.

NP2

FW 4.3.1

Can't wait for my Agent watch to arrive..........

I've made it finally. And it works very good, thanks for the great work you've done.

But sometimes I got exception "System.ArgumentOutOfRangeException', on some kinds of nfc labels.
