Library and example for TI MSP430 LaunchPads and Energia that reads a card number using a RC522 MIFARE module, takes action depending on the card number, and prints it to the serial monitor.
Tested with Energia V16 on the following LaunchPads:
MSP-EXP430G2553 LaunchPad MSP-EXP430F5529 LaunchPad MSP-EXP430FR5969 LaunchPad CC3200 LaunchPad
Tested with Energia V17 on the following LaunchPads:
MSP-EXPF5529 LaunchPad MSP-EXP432P401R LaunchPad - does not work
