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
