New protocol decoder: em4100

Submitted by Uwe Hermann on Thu, 03/10/2016 - 08:07

libsigrokdecode now supports another protocol decoder, em4100.

The EM4100 protocol for certain 100-150kHz RFID tags is layered on top of one of three possible modulation schemes: Manchester, Biphase, or PSK.

Currently the PD only supports Manchester, the other ones can be added later though.

The decoder also works for some compatible RFID tag types such as EM4102 and FK4100.

As usual we have a few example files in our sigrok-dumps repo, and some test-cases is the sigrok-test repo.

The protocol decoder was contributed by Benjamin Larsson, thanks a lot!
