Topic: Open PCD 2 NFC RFID Reader

Hello!

Does anyone here have tried to implement the Open PCD 2 reader with NFC, http://www.openpcd.org/OpenPCD_2_RFID_R … _13.56MHz?

It uses an PN532 NFC controller and an LPC1342 ARM Cortex microcontroller. It seems interesting but I have not found sufficient background on this one.

Exactly same here, it seems really interesting to me but I didn't understand the project goal.

Re: Open PCD 2 NFC RFID Reader

Hi, I am also fiddling around with an open pcd device. At the moment I am thinking about writing a driver (or whatever is necessary) to be able to use it with libnfc. I have some experience programming ARM controllers, but very little experience in programming c on computers. I was browsing the libnfc source a bit today and didn't look too different from stuff I have been doing previously. What would have to be done to get the open pcd device integrated to libnfc? The onboard ARM can be programmed at will and communicates to the PN532 by SPI as far as I know. Would it be possible to emulate the protocol of some device that has already been integrated into libnfc? That would limit the programming to the arm controller. Or would it be better use some custom protocol?

You have to wrote a libnfc's "driver" like Anugrah Redja did for ACR122S:

You could wrote a ARM code that forward input bytes to PN532 using SPI. This way, you could simply clone pn53x_usb or pn532_uart driver and adapt it for you device. That's the easiest way for now.

Does the source code and firmware available in the Open PCD website work? I am currently developing my own Open PCD 2 hardware and I have very little experience in programming ARM controllers.
