Legic Tag Simulator (#666) * FPGA Hi-Simulate: Formatted code * FPGA Hi-Simulate: Fixed documantation * FPGA Hi-Simulate: Freed up 4 LUTs * FPGA Hi-Simulate: Added 212kHz SSP-Clock option * 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. * Legic: Implemented RX and TX for card simulation * Legic: Implemented setup phase for card simulation * Legic: Implemented read command for card simulation * Legic: Implemented write command for card simulation 2018-09-09 22:40:20 +08:00			`// 2018 AntiCat`

Legic: rewrite reader to use xcorrelation and precise timing (#654) * Legic: rewrite reader to use xcorrelation and precise timing - Even tough Legic tags transmit just AM, receiving 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. prng and demodulation - Having all times based on a fixed ts, results in perfect rwd-tag synchronization without magic +/- calculations. * hi_read_tx: remove jerry-riged hysteresis based receiver - This feature got obsolete by a x-correlation based receiver. * Legic: adjusted sampling to new ssp clock speed - Sampling is 4 times faster and pipeline daly reduced to 1/4. The new code samples each bit earyler to account for the shorter pipeline. That introduced bit errors by leeking the next bit into the current one. * Legic: average 8 samples for better noise rejection. * Update CHANGELOG.md 2018-08-21 04:29:34 +08:00			`extern void LegicRfReader(int bytes, int offset);`
