11 // There are three basic operation modes, depending on which device (proxmark/pc)
12 // the signal processing, (de)modulation, transmission protocol and logic is done.
13 // Mode 1:
14 // All steps are done on the proxmark, the output of the commands is returned via
15 // USB-debug-print commands.
16 // Mode 2:
17 // The protocol is done on the PC, passing only Iso15693 data frames via USB. This
18 // allows direct communication with a tag on command level
19 // Mode 3:
20 // The proxmark just samples the antenna and passes this "analog" data via USB to
21 // the client. Signal Processing & decoding is done on the pc. This is the slowest
22 // variant, but offers the possibility to analyze the waveforms directly.
