Most hits are for Raspberry-Pi, so any solution would need to be ported
to the Beagle GPIO libraries. Easiest would be to start with Python and
Adafruit_BBIO. The protocol appears to rely upon both data lines be high as
a NULL state, if either data line goes low you have a 0 or 1 (depending
upon which data line) and both data lines low is an error condition.
However,
https://stackoverflow.com/questions/35148766/python-raspberry-pi-gpio-and-wiegand-issues
implies Python may not be fast enough.
https://gist.github.com/hsiboy/9598741 is an R-Pi C-language source --
again you'd have to update the GPIO calls to some equivalent library on the
Beagle.
Javascript (which may imply node.js usage)
https://github.com/samt/node-wiegand
You may also find sample libraries for Arduino boards, which shouldn't
be too difficult to port over to Beagle GPIO.
