GCA51 is a sketch to attach 2 RC522 RFID readers to an Arduino Nano based LocoIO module. Earlier version were successfully used in RocRail and JMRI.
Beta version 151b includes the updated rfid2ln library, flexible use of 0-2 RC522 readers and startup reporting in the Serial Console and blinking outputs using the Blink Rate board setting.
NOTE: This code is under development as per February 2025 (see Issues).
The code requires GCA51 hardware, available as a PCB or kit from P. Giling.
Follow the Arduino IDE guidelines.
Download the mrrwa LocoNet library as a .ZIP and install it in the IDE using the Sketch > Include Library > Add .ZIP Library... menu.
Also download the rfid2ln library by Immeng. This sketch replaces the included .ino file, but you do need to copy both the rfid2ln.h and the rfid2lnFunc.cpp files to your Arduino IDE project folder.
