RC522 RFID library adapted for Spark

RFID

Update for Libraries 2.0 by Paul Kourany, Jan 2017 - v1.0.3 Adapted for Spark Core by Paul Kourany, May 2014

v0.1.2 - SOS bug fixed, now compatible with all Particle devices

Read a card using a mfrc522 reader on your SPI interface on your Arduino

• Pin layout should be as follows (on Spark Core):
• MOSI: Pin A5
• MISO: Pin A4
• SCK : Pin A3
• SS : Pin A2 (Configurable)
• RST : Pin D2 (Configurable)

conflicting declaration 'typedef uint16_t word'

Veryfing code using this library in Particle Build fails with this error:

MFRC522/MFRC522.h:82:18: error: conflicting declaration 'typedef uint16_t word'
 typedef uint16_t word

Using another SPI interface

Hello Paul,

Can you add support to choose another SPI Interface for MFRC522?
I'm trying to use this on a device which has SPI, SPI1, SPI2 and I cannot use SPI as I need for another device.
Could you please kindly help me out on how I can use SPI1

Thanks,
Kishan

Issue compiling this library

Hi, I'm trying to use the library but get this issue:

Thank you

Fails to complie in Particle Web IDE

Hi there

When compiling this library in the Particle IDE it returns an error

"lib/MFRC522/MFRC522.cpp:1631:1: control reaches end of non-void function [-Werror=return-type]"

It looks like the function MIFARE_UnbrickUidSector is expected to return a value, but isn't doing so in some conditions.

Returning true at the end of this function (around line 1631 of MFRC522.cpp) looks like it should fix the problem.
