21.1 New Features in Stellaris Graphics Librar y
21.1.1 Additions to the ImageButton widget (Reference 9484)
New functionality has been added to the ImageButton widget offered by the Graphics Library.
The widget now supports IB_STYLE_FILL for drawing a background color and new macros al-
low the button background and keycap images to be enabled and disabled. These changes
have been implemented to keep the interface backwards compatible, hence the use of style flags
IB_STYLE_KEYCAP_OFF and IB_STYLE_IMAGE_OFF (since the previous version of the widget
assumed that both images were disabled unless a NULL pointer was used to populate the relevant
image pointer).
21.2 New Features in Stellaris USB Librar y
21.2.1 USB host event driver added to USB library (Reference 9534)
An event driver was added to the USB host library to provide notification of important system events
and class specific events that were previously not visible to the application.
21.3 Bug Fixes in DK-LM3S9B96 Firmware Package
21.3.1 i2s_demo application report wrong elapsed time for 8bit wav files.
(Reference 8973)
There was a problem in the interpretation of the byte rate of .wav files being played that caused the
byte rate calculation to be incorrect by a factor of 2 for 8 bit .wav files.
