Release Notes for StellarisWare Revision 6459 (September 7, 2010)

8.7 Bug Fixes in Stellaris USB Library

8.7.1 StellarisWare was not correctly setting host/device mode. (Reference

12486)

On devices that support forcing the USB OTG controller into host or device mode, the DriverLib and

USB library functions were not properly setting the USB mode. The DriverLib call USBDevMode()

and USBHostMode() will now correctly set the mode for OTG USB controllers that support forcing

the USB mode. These DriverLib functions are also now used in the USB library so that the USB

controller can be forced into the requested mode when either USBDCDInit() or USBHCDInit() are

called.

8.7.2 USB serial device classes could hang if buffers ﬁlled to quickly (Ref-

erence 12461)

The USB library CDC serial class had an issue that could cause the USB software buffers to ﬁll

and never empty. This would most likely occur if the application was using smaller USB buffers or

sending large amounts of data that ﬁlled the USB software buffer in the USB CDC serial device.

This issue has been ﬁxed and now the USB CDC ser ial device will properly hold of the host until

the USB device has made room in the USB software buffers for more data.

8.8 New Features in Stellaris Utility Library

8.8.1 Added Software UART module (Reference 12361)

Added a software UART module (SoftUART) that allows an arbitrary pair of GPIO pins to be used

as a UART. Supports transmit and receive, 5-8 data bits, conﬁgurable parity (even, odd, one, zero,

or none), one or two stop bits, application-conﬁgurable GPIO usage, and application-conﬁgurable

FIFO size.

8.9 New Features in DK-LM3S9B96-EM2 Firmware Pack-

age

8.9.1 Support for TI SimpliciTI low power wireless protocol added (Refer-

ence 12323)

Support for TI’s SimpliciTI low power wireless protocol has been added to StellarisWare. Simplic-

iTI provides a simple application programming interface allowing low power sub-GHz and 2.4GHz

radio communication between devices and access points. The protocol is supported on dk-

lm3s9b96 with EM2 expansion board and one of the following radio transceiver expansion modules

- CC1101:433EM, CC1101:868EM, CC2500EM or CC2520EM.
