| 13 | // the signal processing, (de)modulation, transmission protocol and logic is done. |
| 14 | // Mode 1: |
| 15 | // All steps are done on the proxmark, the output of the commands is returned via |
| 16 | // USB-debug-print commands. |
| 17 | // Mode 2: |
| 18 | // The protocol is done on the PC, passing only Iso15693 data frames via USB. This |
| 19 | // allows direct communication with a tag on command level |
| 20 | // Mode 3: |
| 21 | // The proxmark just samples the antenna and passes this "analog" data via USB to |
| 22 | // the client. Signal Processing & decoding is done on the pc. This is the slowest |
| 23 | // variant, but offers the possibility to analyze the waveforms directly. |
