From: marshmellow42 Date: Tue, 21 Aug 2018 03:08:49 +0000 (-0400) Subject: Add Smartcard functions (RDV4.0) (#646) X-Git-Tag: v3.1.0~26 X-Git-Url: https://git.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/43591e6464af07466ffd87fcb970527ba748253a?ds=inline;hp=f6842317960fbf41cf981171789daebec8dbf803 Add Smartcard functions (RDV4.0) (#646) * allow common makefile options-defines * remove non-existing file references * Uncomment lcd option (still) not enabled by default use Makefile_Enabled_Options.common to enable lcd if desired. * Add Smartcard Functions * add smartcard to menu + make get atr work sc is now functioning as far as my limited knowledge takes me * sc cleanup - add init to all sc commands... because cmds won't work until the first init happens. (multiple inits don't appear to affect it negatively) * default options to exclude Smartcard for main repo * update changelog --- diff --git a/CHANGELOG.md b/CHANGELOG.md index a7e2e045..da6463e9 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -24,6 +24,7 @@ This project uses the changelog in accordance with [keepchangelog](http://keepac - Changed driver file proxmark3.inf to support both old and new Product/Vendor IDs (piwi) ### Added +- Added `sc` smartcard (contact card) commands - reader, info, raw, upgrade, setclock, list (hardware version RDV4.0 only) must turn option on in makefile options (Willok, Iceman, marshmellow) - Added a bitbang mode to `lf cmdread` if delay is 0 the cmd bits turn off and on the antenna with 0 and 1 respectively (marshmellow) - Added PAC/Stanley detection to lf search (marshmellow) - Added lf pac demod and lf pac read - extracts the raw blocks from a PAC/Stanley tag (marshmellow) diff --git a/armsrc/Makefile b/armsrc/Makefile index f0a0c0ff..d4b13c6b 100644 --- a/armsrc/Makefile +++ b/armsrc/Makefile @@ -15,18 +15,22 @@ APP_CFLAGS = -DON_DEVICE \ include ../common/Makefile_Enabled_Options.common -ifneq (,$(findstring LCD,$(APP_CFLAGS))) +ifneq (,$(findstring WITH_LCD,$(APP_CFLAGS))) SRC_LCD = fonts.c LCD.c else SRC_LCD = endif -#SRC_LCD = fonts.c LCD.c SRC_LF = lfops.c hitag2.c hitagS.c lfsampling.c pcf7931.c lfdemod.c protocols.c SRC_ISO15693 = iso15693.c iso15693tools.c SRC_ISO14443a = epa.c iso14443a.c mifareutil.c mifarecmd.c mifaresniff.c mifaresim.c SRC_ISO14443b = iso14443b.c SRC_CRAPTO1 = crypto1.c des.c SRC_CRC = iso14443crc.c crc.c crc16.c crc32.c parity.c +ifneq (,$(findstring WITH_SMARTCARD,$(APP_CFLAGS))) + SRC_SMARTCARD = i2c.c +else + SRC_SMARTCARD = +endif #the FPGA bitstream files.
