+/*
+ * File : main.cpp
+ * License : MIT License
+ * Version : 0.91
+ * Author : Janus Bo Andersen (JA67494)
+ * Last edit : Janus
+ * Created on : 27 Apr 2019
+ * Last change: 03 May 2019
+ * Description: Demo program for Mifare RC-522 RFID reader/writer chip. Will:
+ * : Communicate with RFID readers, transmit card numbers to terminal
+ * : and toggle a digital pin(s) upon reading a card.
+ * Structure : Uses SPI protocol to communicate with the RFIDs.
+ * : Uses U(S)ART to communicate with connected computer/terminal.
+ * Adapted for: STM32 Nucleo L432KC and NXP KL25Z (macro settings).
+ * Changelog : 27 Apr 2019: Created demo program
+ : 02 May 2019: Update pin mappings for FRDM-KL25Z Board
+ : 02 May 2019: Added set and reset for a latched circuit
+ : 03 May 2019: Upgrade to RTOS 5.
+ : 03 May 2019: Run two RFIDs simultaneosuly (changed library setup
+ : by decr. SPI freq. and adding reset managers).

-//Test of cheap 13.56 Mhz RFID-RC522 module from eBay
-//This code is based on Martin Olejar's MFRC522 library. Minimal changes
-//Adapted for Nucleo STM32 F401RE. Should work on other Nucleos too
+/*Connect as follows:
+
+Power supply MUST BE 3.3V and GND to the respective pins.
