This library will allow you to read iClass DH cards with a multiClass HID Card Reader.
These card readers come in two flavors: Wiegand protocol or Clock and Data protocol.
This library currently supports the Clock and Data protocol. Readers that use the Clock and data protocol should have a 'CD' in the model name.
At the moment you need to include
void readBit() { reader.readBit(); }
in the main sketch and attach it to an interrupt in setup()
attachInterrupt(1, readBit, RISING);
You'll see in the example file there is a wrapper function for attachInterrupt() in the setup function. We will work on
