pwpiwi d714d3effc Improvements/Fixes to 14443 sniffing/snooping
- fixed a circular buffer rollover bug in iso14443a.c
- fixed 7 Byte UID handling in hf mf sniff
- fixed "cannot append" error in hf mf sniff d
- fixed hint on mfkey32 in hf mf sim x
- fixed hf mf sniff sometimes showing rogue data from previous calloc
- improve snooping/sniffing by syncing modulation detector window with reader signal (hi_iso14443a.v)
- code cleanup of hi_iso14443a.v

micki.held@gmx.de 552cbc5890 iso14444a: minor FPGA bugfix 2014-02-25 06:49:49 +00:00
micki.held@gmx.de d7aa3739a9 More robust iso14443a sniffing/simulation functions by
- iso14443a.c: less strict Miller/Manchester decoders
- FPGA hi_iso14443a.v: syncing on external readers' clock when simulating and sniffing.

micki.held@gmx.de 7bc95e2e43 - fixed iso1443a ManchesterDecoder in order to fix broken Snoop/Sniff
- enhanced tracing: hf 14a list now shows meaningful timing information. With new option f it also shows the frame delay times (fdt)
- small fix for hf 14b list - it used to run into the trace trailer
- hf 14a sim now obeys iso14443 timing (fdt of 1172 or 1234 resp.)
Note: you need to flash FPGA as well.

roel@libnfc.org d19929cbe8 MAJOR update, added hitag2 reader, emulation and eavesdropping, lots of new code, including FPGA tweaks, part 2 2012-09-18 13:53:17 +00:00
bushing ba06a4b694 setting svn:eol-style=native on files, part 3
(should be done now, sorry)

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
henryk@ploetzli.ch 24fe4dffb4 Jerry-rig a simply hysteresis based receiver into hi_read_tx. Output is via SSC_DIN, which wasn't used in that mode before. 2009-11-06 15:36:57 +00:00
henryk@ploetzli.ch ecf53cb215 Add HF simulator modulation mode for 212kHz subcarrier 2009-10-12 07:46:03 +00:00
henryk@ploetzli.ch db335b3de0 Make objcopy call less verbose
Add master Makefile

henryk@ploetzli.ch 802a36162a New FPGA code for bidirectional LF emulation 2009-08-28 21:54:47 +00:00
henryk@ploetzli.ch e73e717239 Add Makefile for fpga directory (Windows codepath is untested, in any case, go.bat is still there)
Retire rbt2c.pl, instead use objcopy to directly convert the .bit file into an .o that can be linked with the flash image
Rename armsrc/fpga.c to armsrc/fpgaloader.c (since there is now a new fpga.o, created from fpga.bit)
Remove fpgaimg.c from subversion, add fpga.bit
Instead of creating fpgaimage.elf and osimage.elf separately, now create a joined fullimage.elf 
  first (obsoleting ldscript-full), then extract only the fpga and os sections with objcopy
  (This creates unspecific warnings about an empty segment, need to investigate)
Implement a rudimentary .bit parser in the firmware, use that to locate the bitstream in the new
  fpgaimage (which is just a plain copy of the fpga.bit file) and send it to the FPGA
  The code will check the format that's in flash and fall back to the legacy format

d18c7db 8e7a6ce409 This version code now reads a TI tag properly. 2009-07-20 10:36:33 +00:00
d18c7db 4a2d037658 Rubbish file leftover from FPGA compile. Not source code. 2009-07-19 03:52:18 +00:00
d18c7db 72acba7884 Added FPGA passthrough mode for TI tags 2009-07-19 03:51:06 +00:00
d18c7db 1c38843b3f Updated logic in lo_read.v so it's much tidier now, better timing.
Commented source and recompiled FPGA to new fpgaimg.c

edouard@lafargue.name 30f2a7d38f Added LF frequency adjustments from d18c7db, cleaned up code,
typo fixes in iso14443a code, added the missing "tools" directory,
added initial elements for online/offline detection for commands.

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!
