From 07f34835358ef65de310934ae726b66c7ca46f68 Mon Sep 17 00:00:00 2001 From: Andrew Hannam Date: Thu, 6 Dec 2012 18:45:54 +1000 Subject: Restructure Create global include file called gfx.h which knows about sub-system dependancies. Deprecate Touchscreen (GINPUT touch is now working properly) Merge Graph into GWIN Change directory structure to reflect sub-system structure Many small bugs fixed Split Nokia6610 gdisp driver into GE8 and GE12 controller versions Fixed broken demos. GFX sub-systems are now clearly defined and new ones should be much easier to add. --- drivers/gdisp/Nokia6610GE8/gdisp_lld.c | 483 +++++++++++++++++++++++++++++++++ 1 file changed, 483 insertions(+) create mode 100644 drivers/gdisp/Nokia6610GE8/gdisp_lld.c (limited to 'drivers/gdisp/Nokia6610GE8/gdisp_lld.c') diff --git a/drivers/gdisp/Nokia6610GE8/gdisp_lld.c b/drivers/gdisp/Nokia6610GE8/gdisp_lld.c new file mode 100644 index 00000000..beba41a9 --- /dev/null +++ b/drivers/gdisp/Nokia6610GE8/gdisp_lld.c @@ -0,0 +1,483 @@ +/* + ChibiOS/GFX - Copyright (C) 2012 + Joel Bodenmann aka Tectu + + This file is part of ChibiOS/GFX. + + ChibiOS/GFX is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + ChibiOS/GFX is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
