Hi,
I found this device and I'll like to use it hopefully with libnfc. I think this should be straightforward, but this particular device has 4 contact interfaces, one contactless, a keypad and a display. I certainly don't care at all about the display, keypad and the contact interfaces :).
The ACR API PDF talks about how it works, but I'm not well versed in PCSC as to identify what should I do, or if it's way too different than the ACR122 that everyone seems to have available.
I just did a cursory examination of the frames, the slot numbers for the PICC and such, and seem to be similar.
Adding this device as a new supported device on acr122_usb.c I get some activity, but it seems the PC_To_RDR_XfrBlock and RDR_To_PC_DataBlock return an error:
I took it apart, and found that it has a MFRC531, and it's way too different than the PN53x (i.e. different set of commands, formats, etc.).
This is the full command set of the MFRC531 (or the one publicly available):
You think it'd be possible to adapt one of the lower layers (i.e. a pn53x.c like driver) for this? I didn't check if every available command matches the one of the pn53x series, but I can do that.
