Actel A2F200M3F + SunFounder Mifare RC522
Modified version of this arduino code for use with the Actel A2F200M3F boards.
Check out main.c for a quick example program that listens for cards and echos out the ID on contact.
Quickstart
#include <stdio.h>
#include <inttypes.h>
#include "mfrc522.c"
int main() {
// setup does initial pin config, performs a soft reset on the card, and sets
// some sane defaults for the SunFounder Mifare RC522 card
setup();
// now do what you want
// if you just wanted to do a simple read or write to a register on the chip,
// use one of the below commands...
/*
* uchar readd = Read_MFRC522(TxControlReg);
* Write_MFRC522(TxControlReg, 0x03);
*/
return(0);
