Applied PwPiwi's new parity fix.
Applied Marshmellw's fixes for FSKdemod (HID, IO)
FIX: a potential bigbuffer fault given pwpiwi's change inside lfops.c CmdIOdemodFSK & CmdHIDdemodFSK
FIX: change some "int" parameters to uint's.
FIX: changed the lfops.c - DoAcquisition125k_internal to respect pwpiwi's definitions of FREE_BUFFER_OFFSET
HEADS up: The ultralight functions hasn't been verified since pwpiwi's changes.
ADD: found some new default keys
ADD: changed alot of memorys buffers to use constant values. like usbbuffer sizes, tracelogs, etc etc
ADD: all changes Peter filmoore has in his pull request.
FIX: hf mf esave - now supports specifying 0,1,2,4 in card memory for the file to be saved.
ADD: data.h - added FILE_PATH_SIZE constant
ADD: hf legic load - a command help and checks for FILE_PATH_SIZE
ADD: hf legis save - now checks for FILE_PATH_SIZE
ADD: lf hitag - now checks for FILE_PATH_SIZE
ADD: util.c - AddLogLine now checks for FILE_PATH_SIZE
ADD: data load / save - now checks for FILE_PATH_SIZE
FIX: ui.c - added a case of closing a filehandle
FIX: hf mf cload / csave now checks for FILE_PATH_SIZE
FIX: armsrc/mifarecmd.c - adjusted the buffersize in MifareEMemget from 48 to USB_CMD_DATA_SIZE
Fix: removed a call to free, which I think made linux people unhappy during "lf t55xx rd 0"...
Add: "lf t55xx fsk" now kind of outputs binary from "FSK2a R/40 R/50"..
- hf mf rdsc (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (fix): Access Condition 011 not handled correctly (tried to access with key A)
- hf mf restore (add): added (optional) card size parameter and support for non 1K cards
- hf mf nested (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf nested (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf chk (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf eget (fix): displayed three instead of one block
- hf mf eload (add): load 4K .eml files (but accepts 1K .eml files for backwards compatibility)
- hf mf esave (add): always save the whole emulator memory (4K) instead of 1K only
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards
- output of debug messages caused communication failures due to timing issues.
hf mf dbg 4 now required to see these debug messages.
- changed help text for hf mf dbg
- fixed minor bugs in help texts for hf mf sim and hf mf ecset
- display "key A" or "key B" instead of "key=0" or "key=1 in hf mf sim
- tracing was not always enabled when starting hf mf sniff or hf 14a snoop
- ATQA was displayed in wrong byte order in hf mf sniff
- 4 Byte UIDs were displayed as 7 Byte UIDs (padded with 0x000000) in hf mf sniff
- same for logfile names.
- assignment (=) had been used instead of == in comparisons (shouldn't have been relevant though)
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
