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 09c66f1f09 fixing iso14443b (issue #103): fix timing issue (speeding up
the decoders)

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).

henryk@ploetzli.ch 8d40aba58b Add capability to correlate against subcarriers of 212kHz (argument FPGA_HF_READER_RX_XCORR_QUARTER_FREQ | FPGA_HF_READER_RX_XCORR_848_KHZ) and 106kHz (argument FPGA_HF_READER_RX_XCORR_QUARTER_FREQ) 2009-12-09 02:31:01 +00:00
edouard@lafargue.name 6658905f18 Initial commit for the firmware. Used the 20090306_ela version as baseline.
It is identical to the popular 20081211, with the doob addition (20090301), a
linux client, and two additional commands for LF analysis. Let me know if
you find issues here!
