Release Notes for StellarisWare Revision 6852 (January 11, 2011)

5.3 New Features in Stellaris Graphics Library

5.3.1 SliderVerticalSet macro added to GrLib (Reference 12915)

A new macro, SliderVerticalSet, has been added to the slider widget offered by the Stellaris Graph-

ics Library. This macro is intended to allow the vertical or horizontal style to be set when creating a

slider widget dynamically.

5.3.2 SliderBackgroundFillOn and SliderBackgroundFillOff macros added

to GrLib (Reference 12926)

New macros, SliderBackgroundFillOn and SliderBackgroundFillOff, have been added to the slider

widget offered by the Stellaris Graphics Library. These macros allow the background ﬁll style for

the widget to be enabled and disabled dynamically.

5.3.3 Font support extended to allow up to 256 characters to be encoded

(Reference 12947)

The graphics library font support has been updated to allow encoding of any contiguous set of

characters in the 0 to 255 range required to support ISO8859 variants. This encoding uses a

new tFontEx structure to descr ibe the font but this may be used interchangeably with the pre-

vious tFont type merely by casting the pointer. Sample fonts containing encodings of charac-

ters in the range 32 to 255 including western European accented characters can be found under

C:/StellarisWare/third_party/fonts. The ftrasterize tool has been updated with new command line

options to allow selection of the character subset to encode.

5.4 Bug Fixes in Stellaris Graphics Library

5.4.1 Recode some library functions to avoid problems with CCS/TI com-

piler optimizer (Reference 12962)

For some library functions that are coded using inline assembly, if the TI compiler optimization

is completely turned off, the compiler emits code that can result in a stack imbalance for those

functions. The affected functions were recoded to avoid this problem. The affected functions are

SysCtlDelay() and CPUbasepriSet() in driverlib, and WidgetMutexGet() in grlib.
