From 5de79e20f1413a24f3339917176241f3e2681c3d Mon Sep 17 00:00:00 2001 From: iceman1001 Date: Tue, 28 Jul 2015 21:33:09 +0200 Subject: [PATCH] MOD:: reverse back changes to 14443b.c ADD: the hid-flasher/usb_cmd.h wasn't up to date with how it's other file /common/usb_cmd.h looks like. ADD: utils.lua 14443v crc inside LUA. ADD: utils.lua ConvertAsciiToHex method and minor adjustments checks. --- armsrc/iso14443b.c | 2 +- client/cmdhf14b.c | 2 +- client/hid-flasher/usb_cmd.h | 71 ++++++++++++++++++++++++++++++++---- client/lualibs/utils.lua | 40 +++++++++++++++----- client/scripting.c | 29 +++++++++++++-- client/scripts/14araw.lua | 4 +- 6 files changed, 123 insertions(+), 25 deletions(-) diff --git a/armsrc/iso14443b.c b/armsrc/iso14443b.c index fb8b4d66..0ea66a8d 100644 --- a/armsrc/iso14443b.c +++ b/armsrc/iso14443b.c @@ -1275,7 +1275,7 @@ void RAMFUNC SnoopIso14443b(void) if(!ReaderIsActive) { // no need to try decoding tag data if the reader is sending -
