janusboandersen 5:df18de5caf9f 9 * Description: Demo program for Mifare RC-522 RFID reader/writer chip. Will:
janusboandersen 5:df18de5caf9f 10 * : Communicate with RFID readers, transmit card numbers to terminal
janusboandersen 5:df18de5caf9f 11 * : and toggle a digital pin(s) upon reading a card.
janusboandersen 5:df18de5caf9f 12 * Structure : Uses SPI protocol to communicate with the RFIDs.
janusboandersen 5:df18de5caf9f 13 * : Uses U(S)ART to communicate with connected computer/terminal.
janusboandersen 5:df18de5caf9f 14 * Adapted for: STM32 Nucleo L432KC and NXP KL25Z (macro settings).
janusboandersen 5:df18de5caf9f 15 * Changelog : 27 Apr 2019: Created demo program
janusboandersen 5:df18de5caf9f 16 : 02 May 2019: Update pin mappings for FRDM-KL25Z Board
janusboandersen 5:df18de5caf9f 17 : 02 May 2019: Added set and reset for a latched circuit
janusboandersen 5:df18de5caf9f 18 : 03 May 2019: Upgrade to RTOS 5.
janusboandersen 5:df18de5caf9f 19 : 03 May 2019: Run two RFIDs simultaneosuly (changed library setup
janusboandersen 5:df18de5caf9f 20 : by decr. SPI freq. and adding reset managers).
