1 GraphLCD base package Revision History
2 --------------------------------------

5 - added missing include path definition (thanks to Wolfgang Astleitner)
6 - replaced unsigned long long with uint64_t

93 displays (thanks to Lucian Muresan)

95 when skipPixels is equal to width of the character and SubBitmap
96 returns NULL, which was not tested for (thanks to Malte Schröder for
98 - glcdgraphics: fixed a wrong return value in cBitmap::DrawCharacter in

106 - glcddrivers: sed1330: added missing horizontal scrolling
107 initialization. Now, there should be no displaced display any longer.
108 (thanks to Wolfgang Astleitner)

113 should work. (thanks to Detlef Ruge and Ralf Müller)
114 - glcdgraphics: fixed a bug in cBitmap::DrawText that prevented scrolling
116 - glcdgraphics: fixed a bug in cBitmap::SubBitmap.
117 - glcdgraphics: changed the interface of DrawText and DrawCharacter of

122 - crtfont: extended it to support the new font attributes
123 - crtfont: changed file format of description files. Now the font
124 attributes are given by its names, p. e. lineheight:20. Look in
125 README.crtfont for details.
126 - new tool genfont: allows converting of true type fonts to GraphLCD
127 fonts using freetype2 library. You have to uncomment HAVE_FREETYPE2 in
128 Make.config to use it.
129 - added new fonts verdana and verdana bold in sizes 9 to 29 converted by
131 - glcdgraphics: Added additional type casts to std::min calls to make it
132 compile on x86-64 (thanks to Stefan Bergler).
133 - glcddrivers: fixed a bug in serdisp.c. When using direct IO the port
134 string was truncated (thanks to Stefan Bergler).
135 - glcddrivers: Added method cConfig::GetConfigIndex for getting a
136 configuration by its name (thanks to Lucian Muresan).
137 - Added some $(DESTDIR) all over the Makefiles (thanks to Lucian Muresan).

142 - Added some helper functions to GLCD::cFont class
143 - glcddrivers: ks0108: Improved timings: Made setting of display control
144 lines like defined in the controller's data sheet. This fixes problems
145 with some display types. Thanks to Matthias Breitbach for providing a
147 - glcddrivers: gu256x64-3900:
148 - Corrected calculation of m_nTimingAdjustCmd.
149 - Added a test for RefreshDisplay config value to prevent a floating
150 point exception to occur when it is set to zero.
