The Wiegand protocol, also commonly called the Wiegand interface, developed by Motorola, is a wiring standard found on card readers and access control systems, and has become the most common de faction communication method for such systems. The most common format is the standard 26-bit packet. This sample code is based on the N76E003's Timer and GPIO to send and receive 26-bit Wiegand format data.
