Release Notes for StellarisWare Revision 5727 (March 2, 2010)

plication to use it’s own method to power VBUS, this mode remains and new mode was added

to allow the USB controller full control over powering VBUS. This change added the new US-

BHostPwrConﬁg() power conﬁguration function that replaces the old USBHostPwrFaultConﬁg()

function. The old USB_HOST_PWREN_∗ values and the USBHostPwrFaultConﬁg() function have

been deprecated and new values have been added to use with the new USBHostPwrConﬁg() func-

tion. The USB_HOST_PWREN_MAN_LOW and USB_HOST_PWREN_MAN_HIGH allow the ap-

plication to control when power is applied to VBUS and USB_HOST_PWREN_AUTOLOW and

USB_HOST_PWREN_AUTOHIGH will allow the USB OTG controller to have full control over pow-

ering to VBUS.

14.2.2 Add ADC functions to support use of an external reference (Refer-

ence 11494)

Added two new ADC functions, ADCReferenceSet() and ADCReferenceGet(). These can be used

to select internal or external reference for those parts that support an external reference.

14.3 Bug Fixes in Stellaris Peripheral Driver Library

14.3.1 uDMA function uDMAChannelSizeGet() was returning the wrong

value for completed transfers (Reference 11632)

When all of the items had been transferred and the transfer was complete, this function was return-

ing a 1 when it should have returned a 0. This has now been ﬁxed. For all other conditions, this

function was returning the correct value.

14.4 New Features in Third Party Packages

14.4.1 Upgraded to FLTK 1.1.10 (Reference 11551)

The FLTK host toolkit was upgraded from version 1.1.9 to 1.1.10, and the applications which use it

updated as well. This avoid the compile errors seen with some ﬂavors of Linux when using 1.1.9

(therefore allowing the host utilities that use FLTK to build under Linux).

14.5 Bug Fixes in Third Party Packages

14.5.1 Explicit casts added to lwIP TCP_SEQ_LT/LTE/GT/GTE macros

(Reference 11600)

Explicit casts have been added to the parameters passed to the TCP_SEQ_LT, TCP_SEQ_LTE,

TCP_SEQ_GT and TCP_SEQ_GTE macros in lwIP header ﬁle tcp.h to ensure that these versions
