Robert Mosher / Mbed OS door-access-controller-dev

An access controller for man doors at our facility. It receives Wiegand signals from a keypad/card reader and activates a relay to open the door. Access codes are stored in EEPROM. The active code list is updated from TFTP on a local server.

Dependencies:   24LCxx_I2C CardReader USBHOST
