I would like to build a Wiegand device from Raspberry Pi to output 37 bit Wiegand format data to Wiegand control unit receiver.
I don't want to read the Wiegand protocol on Raspberry Pi like from RFID card readers, but instead, I would like to act as something like this.
How can I do it? Is there any HW Wiegand interface for Raspberry Pi and library through which I can send Wiegand data?
I need that Raspberry Pi will output Wiegand 37 bit format data.
Anyone with experience with that?
