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

c2723575de CHG; added an option wither or not to clear emulator mem on init 2016-10-09 18:24:51 +02:00

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'

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

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)

9015ae0f5d CHG: "hf legic dump" now automatically detects tagtype and dumps accordingly. 
CHG:  still #define codestyle  should it be with or without semicolons?

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.

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

CHG: legic timings is better.

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

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

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.

584e28e54b CHG: Minor tweaks, the tracing dissappeared, the spindelay for powering up too long. 2016-09-26 21:40:05 +02:00

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..

3e750be37c ADD: started to add a legic detection to "HF SEARCH" 2016-09-26 20:01:23 +02:00

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.

db44e049b0 CHG: this timing should be quite good. needs to be verified. 2016-09-10 22:47:11 +02:00
iceman1001
b4a6775b5e CHG: a better micro second (us) spindely function. At average it has 8-10us delay, but its linear. Making error less when you want to wait longer.. 
SpinDelayCountUs(20) gives a delay of 28us.
SpinDelayCountUs(100) gives a delay of 110us.
SpinDelayCountUs(500) gives a delay of 508us.

ad5bc8cc8c In my attempts to make the LEGIC code better, its not working now. Timings if off. 
CHG: switching to US clock.
