Innovations-RFID

Innovations ID-2 / ID-12 / ID-20 RFID Reader library for Particle Core (formerly known as Spark Core).

This library is based on "Can You ID This? ID-20 RFID Reader + Arduino" example http://bildr.org/2011/02/rfid-arduino/ with some minor tweaks and checksum function added.

Connections:

RFID Pin	Particle Core Pin
11 (+5V)	VIN
1 (GND)	GND
7 (Format Selector)	GND
9 (D0)	Rx
2 (RES)	D6

Example:

```cpp

#include "innovations-rfid/innovations-rfid.h" #define RFIDResetPin D6

InnovationsRFID rfid = InnovationsRFID();

void setup() { Serial.begin(9600); rfid.setupRFID(RFIDResetPin); }

void loop() { if(rfid.readTag()){ Serial.print(rfid.tag); rfid.clearTag(); //Clear the char of all value } else{ Serial.println("no tag present"); } }
