-INTRO:\r
-\r
-This file contains enough software, logic (for the FPGA), and design\r
-documentation for the hardware that you could, at least in theory,\r
-do something useful with a proxmark3. It has commands to:\r
-\r
- * read any kind of 125 kHz unidirectional tag\r
- * simulate any kind of 125 kHz unidirectional tag\r
-\r
-(This is enough to perform all of the silly cloning attacks, like the\r

-a Verichip. From a technical standpoint, these are not that exciting,\r
-although the `software radio' architecture of the proxmark3 makes it\r
-easy and fun to support new formats.)\r
-\r
-As a bonus, I include some code to use the 13.56 MHz hardware, so you can:\r
-\r
- * do anything that a (medium-range) ISO 15693 reader could\r
- * read an ISO 14443 tag, if you know the higher-layer protocol\r
- * pretend to be an ISO 14443 tag, if you know the higher-layer protocol\r
- * snoop on an ISO 14443 transaction\r
-\r
-I am not actively developing any of this. I have other projects that\r
-seem to be more useful.\r
-\r
-USING THE PACKAGE:\r
-\r
-The software tools required to build include:\r
-\r
- * cygwin or other unix-like tools for Windows\r
- * devkitPro (http://wiki.devkitpro.org/index.php/Getting_Started/devkitARM)\r
- * Xilinx's WebPack tools\r
- * Modelsim (for test only)\r
- * perl\r
-\r
-When installing devkitPro, you only need to install the compiler itself. Additional\r
-support libraries are not required.\r
-\r
-Documentation is minimal, but see the doc/ directory for what exists. A\r
-previous familiarity with the ARM, with digital signal processing,\r
-and with embedded programming in general is assumed.\r
-\r
-The device is used through a specialized command line interface; for\r
-example, to clone a Verichip, you might type:\r
-\r
- loread ; this reads the tag, and stores the\r
- ; raw samples in memory on the ARM\r
-\r
- losamples ; then we download the samples to\r
- ; the PC\r
-\r
- vchdemod clone ; demodulate the ID, and then put it\r
- ; back in a format that we can replay\r
-\r
- losim ; and then replay it\r
-\r
-To read an ISO 15693 tag, you might type:\r
-\r
- hiread ; read the tag; this involves sending a\r
- ; particular command, and then getting\r
- ; the response (which is stored as raw\r
- ; samples in memory on the ARM)\r
-\r
- hisamples ; then download those samples to the PC\r
-\r
- hi15demod ; and demod them to bits (and check the\r
- ; CRC etc. at the same time)\r
-\r
-Notice that in both cases the signal processing mostly happened on the PC\r
-side; that is of course not practical for a real reader, but it is easier\r
-to initially write your code and debug on the PC side than on the ARM. As\r
-long as you use integer math (and I do), it's trivial to port it over\r
-when you're done.\r
-\r
-The USB driver and bootloader are documented (and available separately\r
-for download, if you wish to use them in another project) at\r
-\r
- http://cq.cx/trivia.pl\r
-\r
-\r
-OBTAINING HARDWARE:\r
-\r
-Most of the ultra-low-volume contract assemblers that have sprung up\r
-(Screaming Circuits, the various cheap Asian suppliers, etc.) could put\r
-something like this together with a reasonable yield. A run of around\r
-a dozen units is probably cost-effective. The BOM includes (possibly-\r
-outdated) component pricing, and everything is available from Digikey\r
-and the usual distributors.\r
-\r
-If you've never assembled a modern circuit board by hand, then this is\r
-not a good place to start. Some of the components (e.g. the crystals)\r
-must not be assembled with a soldering iron, and require hot air.\r
-\r
-The schematics are included; the component values given are not\r
-necessarily correct for all situations, but it should be possible to do\r
-nearly anything you would want with appropriate population options.\r
-\r
-The printed circuit board artwork is also available, as Gerbers and an\r
-Excellon drill file.\r
-\r
-\r
-FUTURE PLANS, ENHANCEMENTS THAT YOU COULD MAKE:\r
-\r
-At some point I should write software involving a proper real-time\r
-operating system for the ARM. I would then provide interrupt-driven\r
-drivers for many of the peripherals that are polled now (the USB,\r
-the data stream from the FPGA), which would make it easier to develop\r
-complex applications.\r
-\r
-It would not be all that hard to implement the ISO 15693 reader properly\r
-(with anticollision, all the commands supported, and so on)--the signal\r
-processing is already written, so it is all straightforward applications\r
-work.\r
-\r
-I have basic support for ISO 14443 as well: a sniffer, a simulated\r
-tag, and a reader. It won't do anything useful unless you fill in the\r
-high-layer protocol.\r
-\r
-Nicer (i.e., closer-to-optimal) implementations of all kinds of signal\r
-processing would be useful as well.\r
-\r
-A practical implementation of the learning-the-tag's-ID-from-what-the-\r
-reader-broadcasts-during-anticollision attacks would be relatively\r
-straightforward. This would involve some signal processing on the FPGA,\r
-but not much else after that.\r
-\r
-It would be neat to write a driver that could stream samples from the A/Ds\r
-over USB to the PC, using the full available bandwidth of USB. I am not\r
