SimpleWG

A really simple Wiegand library for Arduino

Features

• Works with any arbitrary Wiegand bit length
• Multi-instance support. Connect independently to as many Wiegand readers as you want! (subject to Arduino memory and pin limits, of course)
• (Hopefully) simple enough to understand

Testing

This has been tested on an Arduino Nano Every, in conjunction of the following readers:

• HID iClass SE RK40
• HID iClass SE R40
• Generic 26-bit EM card reader

Got data on HID iClass SE R40 (R0) (32 bits)
10001010011101100111101100000100

Got data on HID iClass SE RK40 (R1) (4 bits)
0001

Got data on 26-bit EM reader (R2) (26 bits)
10111000100011111101100101

TODO

• Optimize code for style
• Triple-check for memory issues (I don't typically code in C++, so...)
