Release Notes for StellarisWare Revision 7243 (March 19, 2011)

4.3.4 USB Audio Device current volume should be a signed value (Refer-

ence 13235)

The USB audio device class was using an unsigned value to store the current volume setting

received from the host. The USB audio device class now stores the value as a signed value.

4.3.5 USB Audio Device was checking the incorrect parameter on interface

changes (Reference 12991)

The USB audio device class was incorrectly checking the interface number and not the alternate

setting to determine when to enter the active state. This could have caused audio class devices to

not enter the active state in some cases.

4.4 New Features in Stellaris Utility Library

4.4.1 Added random number function to ustdlib.c (Reference 13258)

Two new functions were added to the utility module ustdlib.c. The two new functions usrand() and

urand() provide an easy way to generate pseudo- random numbers.

4.5 Bug Fixes in Stellaris Utility Library

4.5.1 Incorrect macro deﬁnitions in checkpoint.h (Reference 13227)

The previous version of checkpoint.h used the INCLUDE_CHECKPOINTS label incorrectly and

resulted in compilation errors if code included the header and also made calls to checkpoint API

functions. This problem is now ﬁxed and code which includes checkpoint calls can cause those calls

to be compiled out by ensuring that INCLUDE_CHECKPOINTS is not deﬁned during the build.

4.6 New Features in DK-LM3S9B96 Firmware Package

4.6.1 Example applications now use DriverLib in ROM (Reference 13262)

Many of the example applications for dk-lm3s9b96 were previously set up to link ﬂash-based copies

of DriverLib APIs even though those functions are available in the LM3S9B96 ROM. The examples

have now been updated to call the ROM-resident versions of these functions instead.
