pwpiwi ISO15693 device side improvements (#652)
* ISO15693 device side improvements
* increase accuracy by doubling the sample frequency (hi_read_rx_xcorr.v)
* adjust armsrc/iso15693.c and client/cmdhf15.c accordingly
* use more accurate approximation for sqrt(ci^2 + cq^2)
* improve EOF detection (was often mistaken for Logic0, resulting in "error, uneven octet! (extra bits!)")
* hi_read_r_xcorr.v: avoid overflows during accumulation and truncation
* explicitely cast unsigned ADC samples to signed

proxmark3: the official Proxmark repository!

The proxmark3 is a powerful general purpose RFID tool, the size of a deck of cards, designed to snoop, listen and emulate everything from Low Frequency (125kHz) to High Frequency (13.56MHz) tags.

This repository contains enough software, logic (for the FPGA), and design documentation for the hardware that you could, at least in theory, do something useful with a proxmark3.

Resources

Development

The tools required to build or run the project will vary depending on your operating system. Please refer to the wiki for details.

Obtaining hardware

The Proxmark3 is available for purchase (assembled and tested) from the following locations:

Most of the ultra-low-volume contract assemblers could put something like this together with a reasonable yield. A run of around a dozen units is probably cost-effective. The BOM includes (possibly- outdated) component pricing, and everything is available from Digikey and the usual distributors.

If you've never assembled a modern circuit board by hand, then this is not a good place to start. Some of the components (e.g. the crystals) must not be assembled with a soldering iron, and require hot air.

The schematics are included; the component values given are not necessarily correct for all situations, but it should be possible to do nearly anything you would want with appropriate population options.

The printed circuit board artwork is also available, as Gerbers and an Excellon drill file.
