FIX: iso14443b.c got some minor adjustments in the demod and codeas14443btag. Seems it works better for me.
I still have the problem with powerup of a 14b tag. I need to run the "14b raw -c -p 05 00 08" a couple of times before I get an answer.
FIX: 14b sim changes in iso14443b.c , *experimental* I took some timing loops from "14a sim" armsrc/iso14443a.c and merged it into the "14b sim". Now using two pm3's I can have one simulating and the other reading and it works. Ask @pwpiwi if you want to know more of what those timing loops does. Something about waiting for the fpga delay queue...
- fix: IQ demodulator (FPGA)
- fix: approximately align reader signal delay to tag response delay (FPGA)
- fix: remove deprecated RSSI calculation to improve decoder speed (iso14443b.c)
- fix: better approximation of signal amplitude to avoid false carrier detection (iso14443b.c)
- fix: remove initial power off in iso14443b raw command (iso14443b.c)
- add: enable tracing for iso14443b raw command (iso14443b.c)
- fix: client crashed when checking CRC for incomplete responses (iso14433b.c)
- speeding up snoop to avoid circular buffer overflow
- added some comments for better documentation
- rename functions (iso14443 -> iso14443b)
- remove unused code in hi_read_rx_xcorr.v
- most significant bit of tag data (which happens to be the sign bit)
had been dropped when snooping (FPGA change)
- avoid trying to decode both tag and reader data when snooping (we don't
have the time to do so).
