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'

8ddfbc34dc CHG: the call to TurnReadLFOn has a delay / number as parameter. Seems to be gone. 
FIX:  fixes to EM4050 code since when I changed the timer.  It should work nice now.

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)

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.

CHG: downloading eml memory from device should use uint's
CHG: "hf legic read" has a different printing. It now prints 32bytes / row

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..

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.

e1deabc0eb CHG: fixes a "indent" warning 2016-09-26 11:04:04 +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
d5bded10e2 CHG: lowered the timout again, but re-added the spindelay since 14a requires 5ms powerup before entering the idle-state where tag starts to listen. 
CHG: fix the ticks compare xx > 1 into  xx >= 1
 2016-09-23 23:23:17 +02:00

f885043422 FIX: "hf 14a read" / "hf mf *" / "hf mfdes info" and failure when calling these commands serveral times in row. 
For long transactions the sspclock compare with >1 instead of >=1 ..   Now the timer resets properly.
CHG: use some #define constants for iso-commands.

24c49d36ba FIX: This commit fixes the broken LF since I change the spindelay calls. The original problem is that spindelayus calls is incremented with21.3us each step, making it very hard to find exact timings found in the datasheets for T55x7, HID etcetc. When @marshmellow and I looked into this 2014, I had this on my back of my mind but forgot it since I didn't know how the source code / pm3 worked. This behavior in spindelayus has given the bit-period for ON/OFF measured in (us) very hard to find. Its kind of magic that it worked so far so good. Well until I started to look into the "hf legic" bitbanging ASK ON/OFF keying and that one needs a much more precis timer. Same goes for the PCF7931 code. 
I've added a precise timer in the new files ticks.c and moved some older stuff from util.c to have a solid base for this.
UNTESTED,  and the timings measured for t55x7 in lfops.c and other parts has not been adjusted to this "correct" timer.

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

78f59945a7 fixed indentation to get rid of warnings 
warnings are treated as errors, so a warning due to misleading
indentation is kinda annoying

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.

5d15891e2b FIX: Even the US clock had the issues with not resetting properly. Now its always ZERO when you call StartCountUS. 2016-09-09 11:57:31 +02:00
