Andreas Dröscher 78d5188922 change: legic reader now uses xcorrelation and ssc based io
- Even tough legic tags transmit just AM using xcorrelation
   results in a significantly better signal quality.
 - Switching from bit bang to a hardware based ssc frees
   up CPU time for other tasks e.g. demodulation

pwpiwi da586b1702 fixing iso14443b (issue #103):
- revert removal of FPGA_HF_READER_RX_XCORR_848_KHZ. Need to be able to switch to 424kHz for ISO15693.

pwpiwi 51d4f6f114 fixing iso14443b (issue #103):
- 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

pwpiwi 5b95953d42 fixing iso14443b (issue #103):
- 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).

pwpiwi 30364d2711 fix: broken edge detector implementation in hi_iso14443a.v resulted in decreased sensitivity 2015-03-09 20:01:37 +01:00
pwpiwi 7554370c30 bugfix hf 14a sim / hf mf sim: polarity of tag subcarrier modulation was wrong 2015-02-11 21:14:34 +01:00
Martin Holst Swende 645c960f61 Implemented new FPGA mode for iclass tag simulation. Reduces arm-side size of transfer/memory by a factor of 8. Makes for easier arm-side encoding of messages, for when we start needing to do that on the fly instead of using precalculated messages 2015-01-15 15:16:34 +01:00
iZsh 7cc204bff8 THIS REQUIRES A BOOTROM UPDATE!! To save FPGA area, split the LF and HF bitstreams and load them on-demand. 2014-06-20 01:02:59 +02:00
