.. ntag simulation stuff from @marshmellows branch "ntag/sim" .. hf mf mifare fixes from @pwpivi. .. hw status command .. speedtest function from @pwpivi .. Viking Functionalities, (not a proper DEMOD, but a start) .. GetCountUS better precision from @pwpivi .. bin2hex, hex2bin from @holiman ... starting with getting the T55x7 CONFIGURATION_BLOCK for different clone situations. Ripped from Adam Lauries RFidler, nothing working or finished.. ... Started working with the T55x7 read command with password actually performs a write block... See Issue #136 https://github.com/Proxmark/proxmark3/issues/136 Not solved yet. ... Started add SHA256.. not working yet..
