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

2.13 Bug Fixes in EK-LM3S9B96 Firmware Package

2.13.1 usb_dev_audio example was incorrectly adjusting sample rate (Ref-

erence 13896)

The usb_dev_audio example was incorrectly checking the condition when increasing the sample

rate of the I2S interface. This occurred when input buffer was ﬁlling faster than the output was being

drained. This caused periodic noise in the output audio when the circular buffer pointers crossed

each other. The check for the distance between the buffer pointers has been ﬁxed to properly adjust

the sample rate in all cases.

2.14 New Features in EK-LM4F232 Firmware Package

2.14.1 Windows data logging application added (Reference 13826)

A new application, “logger”, has been added to the StellarisWare/tools directory. This is a PC front

end for the “qs-logger” data logging application included in the ek-lm4f232 StellarisWare release. If

the ek-lm4f232 is connected to a PC via the USB OTG connector and the qs-logger storage option

is set to “Host PC”, then this application can be used to view captured data samples and log them

to a ﬁle.

2.14.2 Added support for EK-LM4F232 and Cortex M4F (Reference 13867)

Support has been added to StellarisWare for the new Cortex M4F-based ek-lm4f232 evaluation

kits.

2.15 New Features in RDK-IDM Firmware Package

2.15.1 FontView example application added (Reference 13807)

A new example application has been added to allow the contents of a Stellaris graphics library font

ﬁle to be displayed. This program illustrates the newly-added international character set support

and will show all the glyphs encoded in a binary font stored as FONT.BIN in the root directory of

the SDCard FAT ﬁle system or, if this ﬁle doesn’t exist, the contents of a sample font built into the

executable.
