Subject: ADD: added a method for le32toh.  Converting bytes to uint32_t .
X-Git-Url: http://cvs.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/c805748f340391011d647f7f524d1744563ddec1

ADD: added a method for le32toh.  Converting bytes to uint32_t .
CHG: correct use of FILE_PATH_SIZE in the tracelogging functions.
