9455b51c 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.
