3b2fee43ea New LF edge detection algorithm + lowpass filter 
This is a new LF edge detection algorithm for the FPGA.

- It uses a low-pass IIR filter to clean the signal
(see https://fail0verflow.com/blog/2014/proxmark3-fpga-iir-filter.html)
- The algorithm is able to detect consecutive peaks in the same
  direction
- It uses an envelope follower to dynamically adjust the peak thresholds
- The main threshold used in the envelope follower can be set from the ARM side

fpga/lf_edge_detect.v,
fpga/lp20khz_1MSa_iir_filter.v,
fpga/min_max_tracker.v: New file.

fpga/lo_edge_detect.v, fpga/fpga_lf.v: Modify accordingly.

armsrc/apps.h (FPGA_CMD_SET_USER_BYTE1,
FPGA_CMD_SET_EDGE_DETECT_THRESHOLD): New FPGA command.
fpga/fpga_lf.v: Modify accordingly/Add a 8bit user register.

fpga/fpga_lf.bit: Update accordingly.

fpga/tests: New directory for testbenches

fpga/tests/Makefile: New file. It compiles the testbenches
and runs all the tests by default (comparing with the golden output)

fpga/tests/tb_lp20khz_1MSa_iir_filter.v,
fpga/tests/tb_min_max_tracker.v,
fpga/tests/tb_lf_edge_detect.v: New testbenches

fpga/tests/plot_edgedetect.py: New script to plot the results from
the edge detection tests.

fpga/tests/tb_data: New directory for data and golden outputs

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.

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.

d2f487af9c Various improvements on the Mifare1kSimulation. Fixed issue with tracebuffer not being cleared, fixed issue with 'static' errors, added modes for doing reader-only attack, added interactive mode, added possibility to set UID from cmdline, either 7-byte or 4-byte.
