From: marshmellow42 Date: Mon, 17 Apr 2017 22:37:23 +0000 (-0400) Subject: new grid X offset calcs to fix some issues X-Git-Tag: v3.0.0~12^2~3 X-Git-Url: https://git.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/refs/heads/graphwork2 new grid X offset calcs to fix some issues also fixed a save_restore issue with grid alignments now save_restoreGB() saves/restores offset values added macro enumeration of SAVE vs RESTORE for save_restore commands. --- diff --git a/client/cmddata.c b/client/cmddata.c index 87c54231..c12c2ce6 100644 --- a/client/cmddata.c +++ b/client/cmddata.c @@ -71,7 +71,7 @@ void save_restoreDB(uint8_t saveOpt) static int savedDemodStartIdx = 0;
