* add "samples to skip" for lf config (mainly for lf snoop)
* add lf em 4x05protect command to write protection on em4x05 chips
* fix spacing
* and remove old comment git added back in..
* update changelog
* fix flags - only need 1 bit
* Add raw HF signal plotting
* new fpga module hi_get_trace.v - store A/D converter output to circular buffer on FPGA
* new command 'hf plot' - pull data from FPGA and display it in Graph Window
* rework iso14443b device functions
* hf_read_rx_xcorr.v: transfer i/q pair in one 16bit frame
* hi_read_tx.v: invert ssp_dout. When nothing is transferred (ssp_dout=0), this results in no modulation (carrier on)
* adjust arm sources accordingly
* iso14443b.c: switch off carrier after hf 14b sri512read and hf 14b srix4kread
* iso14443b.c: fix DMA circular buffer handling
cotag read could enter endless loop, now cancels if the next bit doesn't
appear
em4x05 detection would loop due to a threshold never being met, now has
a dump out after 1000 samples tested.
fixed some indenting in hitag2 while i was reviewing that code for
potential endless loops...
add parameter for # bits to read
auto get samples after lf read/snoop (don't need to do a `data samples`
anymore)
add safe function to get DemodBuffer
add some lf demod comments and apply new lf_read function instead of
read then get samples.
fixed output bug in lf t55xx config print
fixed small bug in lf t55xx detect during ST check
slight adjustment to lf t55xx sampling code to start at the same spot
more consistently
reduce indala detection false positives
lf t55xx commands heavily tested and seem to be stable and reliable on
most modulations/bitrates (excluding Sequence Terminator configured
cards).
@iceman1001 s cleanup of some t55xx read code, plus some timing tests to
improve lf t5 detect/read...
small typo in pcf 16 address bytes instead of 4...
add option for verbose or not on bigbuf clear cmd.
adjust lf config threshold to coincide with graph values and trigger on
highs over the threshold or lows under the threshold * -1
split general hf 14b reader from full info printing
applies icemans full ata55x7 read/write settings
adds checksum to ioprox (thanks to iceman)
adds silent mode for lf read and getSamples
fix lf em em410xwatch and lf em410xspoof
improve data rawdemod ar - for biphase demods
improve detectclock a for strong antennas
