Andreas Dröscher 3029223158 change: legic reader now uses xcorrelation and ssc based io 
- Even tough legic tags transmit just AM using xcorrelation
   results in a significantly better signal quality.
 - Switching from bit bang to a hardware based ssc frees
   up CPU time for other tasks e.g. demodulation

Andreas Dröscher 8f797d1388 change: legic reader tx back to bigbang 
I've tried to modulate the Legic specific pause-puls using ssc and the default
ssc clock of 105.4 kHz (bit periode of 9.4us) - previous commit. However,
the timing was not precise enough. By increasing the ssc clock this could
be circumvented, but the adventage over bitbang would be little.

iceman1001 46a0ec7130 CHG: removed old TRUE/FALSE defines... some left still.. 2017-07-27 09:28:43 +02:00
iceman1001 24d332fac7 fixes.. 2017-07-11 18:27:59 +02:00
iceman1001 f8ff1483eb CHG: "hf legic sim" old imp, uses two timers, we have one. I'm seriously starting on thinking about a UART instead, to read the dmabuffer. If only I knew howto. 2016-10-10 21:52:58 +02:00
iceman1001 c2723575de CHG; added an option wither or not to clear emulator mem on init 2016-10-09 18:24:51 +02:00
iceman1001 539fd59ebe CHG: "hf legic write" - now writes on the limits better. 
CHG: "hf legic restore" - now restors :)
CHG: "hf legic rdmem" - now has a nice offset row above the read data.  try:  'hf legic rdmem 0 100'
 2016-10-09 15:41:31 +02:00
iceman1001 cd79d97223 CHG: syntax suger 2016-10-08 19:14:35 +02:00

iceman1001 4409bf6ef3 CHG: "hf legic write" with these I managed to get one byte written. Its a start. 2016-10-07 22:16:38 +02:00
iceman1001 715bed5023 CHG: adjustments to 3.6ms 2016-10-07 21:28:09 +02:00

iceman1001 e4d57949df FIX: wrong log bytes... 2016-10-07 19:15:08 +02:00
iceman1001 b816886806 FIX: one send command bug fixed. Turns out that uint16_t is too small for 21/23bits size. Who figured? 2016-10-07 19:11:38 +02:00
iceman1001 27c4a862f6 FIX: unused variable removed. 
CHG: start remaking the used timers in "Hf legic write"
 2016-10-07 12:23:07 +02:00
iceman1001 f0fa663814 CHG: "hf legic write" got a make over in how its called. Now called with 'offset' and 'data' 
'hf legic write o 10 d 11223344'  -  this will write 4 bytes (0x11,0x22,0x33,0x44) to tag from offset 10 (0x0A)
 2016-10-07 11:58:14 +02:00
iceman1001 e4a8d1e2ac CHG: started the process of fixing "hf legic write" and "hf legic sim" commands. 2016-10-07 00:15:47 +02:00
iceman1001 0e8cabed8d ADD: "hf legic eload" - Load binary file to emulator memory. Use "h" for help text

iceman1001 9015ae0f5d CHG: "hf legic dump" now automatically detects tagtype and dumps accordingly. 
CHG:  still #define codestyle  should it be with or without semicolons?
 2016-10-05 22:58:06 +02:00
iceman1001 b1cd7d5ca6 FIX: one too many semicolons for #defines 2016-10-05 22:18:26 +02:00

FIX:  "hf legic dump" is almost there.
 2016-10-05 22:07:32 +02:00
iceman1001 633d068682 CHG: command name changes.. 
old "hf legic info" is now "hf legic reader"
old "hf legic read" is now "hf legic rdmem"
old "hf legic decode" is now "hf legic info"

ADD:  new command "hf legic dump",  which will autodetect tagtype and dump all mem to a binary file.
 2016-10-05 21:42:13 +02:00
iceman1001 635d6e9bef CHG: code clean up 2016-10-05 17:10:29 +02:00
iceman1001 c15e07f11d CHG: making timings a bit tighter == faster read of tag. Like 1ms for whole tag. 
FIX:  off-by-one bug in read-byte-loop.
 2016-10-04 23:08:39 +02:00
iceman1001 7a8db2f678 CHG: "hf legic read" - increased timeout values client side, reading MIM1024 takes a bit of time 2016-10-04 21:26:19 +02:00
iceman1001 86087eba00 Textual changes in helptext. Still no clear. 2016-10-04 18:43:11 +02:00
iceman1001 7bc3c99e7e CHG: "hf legic write" started to change this command to the updated code 2016-10-04 18:05:55 +02:00
iceman1001 77a689dbeb CHG: revert legiccrc8 to old algo. 
CHG: "hf legic decode" now loads EML memory
CHG: legic timings is better.
 2016-10-04 00:07:07 +02:00
iceman1001 0b0b182fe2 CHG: changed to use BigBuff_Eml memory instead of big_buff_malloc. 
CHG: downloading eml memory from device should use uint's
CHG: "hf legic read" has a different printing. It now prints 32bytes / row
 2016-10-03 23:24:59 +02:00
iceman1001 c649c43389 CHG: finally, the ticks timer does what it is supposed to do. 32bits and working. 2016-09-29 21:36:43 +02:00
iceman1001 fabef615ec CHG: added addresize to legic select struct. 
CHG: TIMER, it turns out the TC0, TC1 and TC2 is only 16bit.  So adjust to use two clocks to get a 32bit timer.
CHG: code clean up in legic device side.  consistency with variable names..
 2016-09-29 17:43:39 +02:00
iceman1001 cb7902cdcd CHG: removed some debug data 
CHG: reverted back to old crc imp.

iceman1001 a39944216d CHG: a select_legic function with structs and stuff and 2016-09-29 12:23:09 +02:00
iceman1001 d7e24e7c5f CHG: 'hf list legic' doesn't print the parity now. 
CHG: 'hf legic read' the device side timings is starting to look much better. HUGE Thanks to @will-rbnt for endless checks and logic analyser feedback. Without his effort this would not work. What does work? We can now use ANY IV in legic. The PM3 Master version is flawed, will only work with IV=0x55.

---still broke--- my crc implementation.. I know I'm about to look into it.

iceman1001 584e28e54b CHG: Minor tweaks, the tracing dissappeared, the spindelay for powering up too long. 2016-09-26 21:40:05 +02:00
iceman1001 62577a62ae FIX: Much of my added extra legic code is commented away now. 
FIX: the gcc6.1.1 warning broke my gcc 4.8.4 build env..
 2016-09-26 20:21:31 +02:00
iceman1001 3e750be37c ADD: started to add a legic detection to "HF SEARCH" 2016-09-26 20:01:23 +02:00
iceman1001 faabfafe30 CHG: using bitsend to determind the legic annotation in "hf list legic" makes false positives much less. 2016-09-26 12:26:37 +02:00
iceman1001 25d52dd261 CHG: according to measureement by @wilrn the actual timing for receiving tag data, is 90us (ONE) and 100us (ZERO) which is not mentioned anywhere before. What a find! 2016-09-24 15:15:24 +02:00
iceman1001 22f4dca88c CHG: extracted some timers functionality, to get unified access to a timer/clock which counts in ticks. Moved stuff from util.c 2016-09-21 19:03:32 +02:00
iceman1001 87342aadbc CHG: adjusted timing according to @sentinel 's traces 2016-09-14 16:18:04 +02:00
iceman1001 111c6934d4 CHG: Small steps, the waiting time between frames was unclear. At least now the tags answers to a readbyte command after the setup phase. 2016-09-12 09:19:49 +02:00
iceman1001 76471e5d17 CHG: reverted back from the idea of measureing in (us) microseconds, the timer is too raw, gives 10-15us delays. Now we are measuring ticks, which is (1 us = 1.5ticks) 
like it was before.   ie:  80us = 80*1.5 = 120ticks.
