Release Notes for StellarisWare Revision 8028 (September 9, 2011)

was targeted. Separate project and make ﬁles are provided for each target core.

Note that this change will require modiﬁcation in existing application project and make ﬁles to link the

correct version of the library from its new directory. This change has been made for all StellarisWare

board examples.

2.2 New Features in Stellaris Graphics Library

2.2.1 Added support for international character sets (Reference 13789)

New APIs have been added to the Stellaris Graphics Library to allow support for text codepages,

source text encoding using UTF-8 and rendering international characters. The ftrasterize tool has

also been updated to support a new font format which allows encoding of multiple contiguous blocks

of glyphs from the entire Unicode range. Further information on these new features can be found

in the Stellaris Graphics Library User’s Guide.

2.2.2 Updates to ftrasterize (Reference 13781)

The ftrasterize tool has been updated to support a new font format added to allow rendering of

international character sets. The tool will also generate binary format fonts that can be used from a

ﬁle system or non-random-access memory with an appropriate font wrapper module.

2.2.3 Additions to and reorganization of graphics library fonts (Reference

13774)

With the addition of international text support in the Stellaris Graphics Library, several new fonts

have been added to the collection found under third_party/fonts. These include Chinese, Japanese

and Korean fonts in addition to several new sizes of the existing Latin fonts. As part of this change,

the directory has been rearranged to ensure that fonts covered under different licenses are grouped

together. third_party/fonts now contains three subdirectories, oﬂ, apl and other, each containing

a header ﬁle for the fonts contained there. If you previously used the third_party/fonts/fontex.h

header, this is now found as third_party/fonts/oﬂ/oﬂ_fonts.h and the font source ﬁles have moved

to the same location. Additionally, all fonts are also now provided in the new binary format that will

allow them to be used from a ﬁle system or other non-random-access memory via an appropriate

font wrapper module.

2.2.4 Libraries renamed in adding support for Cortex M4F (Reference

13852)

This release adds support for the ek-lm4f232 kit and our new Cortex M4F-based parts. With the

addition of the new core and, speciﬁcally, its hardware ﬂoating point unit, we have had to split our

libraries into two versions, one for the Cortex M3 and another for the Cortex M4F. To prevent the

possibility of confusion, libraries are now renamed with a“-cm3” or “-cm4f” sufﬁx indicating the core

they were built for. Similarly, project ﬁles and makeﬁles are set up to use these sufﬁxes in the
