I have absolutely no idea how to connect up my digispark pro with an RFID RC522 module (
http://www.amazon.co.uk/Sintron-Reader-Writer-Module-Arduino/dp/B00DSKGYQS/ref=sr_1_1?ie=UTF8&qid=1438160529&sr=8-1&keywords=rfid+arduino), I tried connecting it to the same pins as on my arduino uno where I had success, but couldn't get it to work on my pro!
My software:
// Example sketch to read the ID from an Addicore 13.56MHz RFID tag
// as found in the RFID AddiKit found at:

#include <SPI.h>
#define uchar unsigned char
#define uint unsigned int
//4 bytes tag serial number, the first 5 bytes for the checksum byte
uchar serNumA[5];
uchar fifobytes;
uchar fifoValue;
AddicoreRFID myRFID; // create AddicoreRFID object to control the RFID module

const int chipSelectPin = 10;
const int NRSTPD = 5;

//Maximum length of the array
#define MAX_LEN 16
void setup() {
Serial.begin(9600); // RFID reader SOUT pin connected to Serial RX pin at 9600bps
// start the SPI library:
SPI.begin();
pinMode(chipSelectPin,OUTPUT); // Set digital pin 10 as OUTPUT to connect it to the RFID /ENABLE pin
digitalWrite(chipSelectPin, LOW); // Activate the RFID reader
pinMode(NRSTPD,OUTPUT); // Set digital pin 10 , Not Reset and Power-down
digitalWrite(NRSTPD, HIGH);
pinMode(LED, OUTPUT);
myRFID.AddicoreRFID_Init();
}
void loop()
{
uchar i, tmp, checksum1;
uchar status;
uchar str[MAX_LEN];
uchar RC_size;
uchar blockAddr; //Selection operation block address 0 to 63
String mynum = "";
str[1] = 0x4400;
//Find tags, return tag type
status = myRFID.AddicoreRFID_Request(PICC_REQIDL, str);
if (status == MI_OK)
{
Serial.println("RFID tag detected");
Serial.print(str[0],BIN);
Serial.print(" , ");
Serial.print(str[1],BIN);
Serial.println(" ");
}
//Anti-collision, return tag serial number 4 bytes
status = myRFID.AddicoreRFID_Anticoll(str);
if (status == MI_OK)
{
checksum1 = str[0] ^ str[1] ^ str[2] ^ str[3];
Serial.println("The tag's number is : ");
//Serial.print(2);
Serial.print(str[0]);
Serial.print(" , ");
Serial.print(str[1],BIN);
Serial.print(" , ");
Serial.print(str[2],BIN);
Serial.print(" , ");
Serial.print(str[3],BIN);
Serial.print(" , ");
Serial.print(str[4],BIN);
Serial.print(" , ");
Serial.println(checksum1,BIN);
// Should really check all pairs, but for now we'll just use the first
if(str[0] == 113) //You can change this to the first byte of your tag by finding the card's ID through the Serial Monitor
{
Serial.print("Tag!\n");
if (state == 0) {
digitalWrite(LED, HIGH);
state = 1;
} else {
digitalWrite(LED, LOW);
state = 0;
}
} else if(str[0] == 135) { //You can change this to the first byte of your tag by finding the card's ID through the Serial Monitor
Serial.print("Card!\n");
}
Serial.println();
delay(1000);
}
myRFID.AddicoreRFID_Halt(); //Command tag into hibernation
}
Help would be massively appreciated as I'm very inexperienced.
