etmatrix	0472d76de4	The great work of Enio hf snoop is now ported into latest version in git ... you can find original work here https://github.com/EnioArda/proxmark3	2015-10-23 15:40:35 +02:00
pwpiwi	705bfa1058	fixing iso14443b (issue #103): ... - increased DMA_BUFFER_SIZE to avoid occasional circular buffer overflows. - minor code cleanups	2015-06-22 22:03:43 +02:00
pwpiwi	467340996e	fixing iso14443b (issue #103): ... - fix hf 14b snoop - fix hf 14b sim	2015-06-21 18:04:24 +02:00
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.	2015-06-18 15:41:30 +02:00
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	2015-06-17 20:27:36 +02:00
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).	2015-06-02 22:50:16 +02:00
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
