Colin J. Brigato 7e12fc0ceb Pass 2; commit 3/3; 2018-09-06 05:34:48 +02:00
Colin J. Brigato 368fe11df0 Second Pass rewrite of flashmem. added command 'mem spibaud' to switch between 24/48Mhz operation. All is more consistant, less messy. All logic rewrittent avoiding multiple flashinit/flashstop. busywait is now at it's lowest possible. Beware : 48Mhz is VERY buggy cause of sillicon bug (see source for more info), and doesn't give much more than 24Mhz for now since we doubled nearly every operation speed here. 2018-09-06 05:15:52 +02:00

AntiCat 61e4eac2b2 Legic: Moved card simulator into separate file & cleaned interface.
Reader and card simulation have almost no common code. Moreover the sim
uses an SSP Clock at 212kHz for all timings to prevent any drifting from
the PRNG. This clock speed is not available in reader simulation mode (SSP
runs at up to 3.4MHz, and changes speed between TX and RX). For these
reasons having the code in separate files makes it significantly cleaner.

Colin J. Brigato 8d673fa1bf First pass rewrite of flashmem driver for optimization. Lot of changes here. Provides PoC of saving and recalling a tag in Standalone mode. Added some printing passthrough to client to azccomodate for vt100 eye-candyness. FastREAD mode implemented for flashmem, testable from client. Beta but functionnal. Reading the whole flash with 1Kb to 32kb buffers was ~730ms, now 380ms Max (even at 24Mhz spi baudrate) 2018-09-03 00:02:44 +02:00

Andreas Dröscher 9ba20b590a change: reduced demodulator to bare minimum
The initial code added complexity without improving reading distance.
Thankfully the peak detection signal path has a low noise floor.

Andreas Dröscher 9d330dde87 fix: 32bit tick timer based on TC0 and TC1
TC1 counts the number of TC0 overflows (carry bits).
In random conditions TC1 would return or stay at zero,
instead of counting up. This due to the behavior of the
reset signal.

SAM7S Series Datasheet, 33.5.6 Trigger:
Regardless of the trigger used, it will be taken into account
at the following active edge of the selected clock. This means
that the counter value can be read differently from zero just
after a trigger, especially when a low frequency signal is
selected as the clock.

The new code first prepares TC1 and asserts TC1 trigger and
then prepares TC0 and asserts TC0 trigger. The TC0 start-up
will reset TC1.

Andreas Dröscher c06f0af7f3 change: switched from timestamps (us) to ticks
GetCountUS() has a jitter of +/- 7us this is not precise
enough to keep the PRNG in sync. 1.5 * GET_TICKS on the
other hand is spot on.

Andreas Dröscher 7244f5825d 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.

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
2018-08-12 09:59:48 +02:00
Andreas Dröscher c59150657c add: xcorr 211.875 kHz option
The FPGA supported this frequency for a long time, just the ARM code
had no define to enable it.

Andreas Dröscher e779f06c5e change: clean up Legic interface
I see no adventage in poluting all sources that include legicrf.h
with our internal depedencies (includes) and function names.
