Release Notes for StellarisWare Revision 6075 (June 4, 2010)

rupts are enabled or disabled at the CPU level. A non-zero return code indicates that interr upts are

currently disabled.

10.3 Bug Fixes in Stellaris Peripheral Driver Library

10.3.1 USB_EP_HOST_IN and USB_EP_DEV_OUT deﬁnitions overlap

with USB_EP_SPEED_FULL deﬁnition (Reference 12152)

The USB_EP_HOST_IN and USB_EP_DEV_OUT values had the same bit ﬁeld position in the bit

ﬂags as the USB_EP_SPEED_FULL ﬂag causing an overlap that resulted in errors when these

ﬂags were used. The functions affected were the USBFIFOFlush(), USBEndpointDMAEnable(),

and USBEndpointDMADisable(). The USB_EP_HOST_IN and USB_EP_DEV_OUT are now sim-

ply the bitwise NOT of the USB_EP_HOST_OUT and USB_EP_DEV_IN to remove this collision

and all uses of these bits have been changed to match this deﬁnition.

10.3.2 USBDevEndpointStallClear() is not clearing data toggle for non-zero

endpoints (Reference 12165)

When the USBDevEndpointStallClear() function is called for non-zero endpoints and the ulFlags pa-

rameter is USB_EP_DEV_OUT, the function sets the wrong bit and does not clear the data toggle.

This error causes the USB controller to ignore valid DATA0 packets after the USBDevEndpointStall-

Clear() is called. This has been ﬁxed and now the USBDevEndpointStallClear() function properly

clears the data toggle when called.

10.3.3 Deprecated INT_ADC? from hw_ints.h (Reference 12203)

The deﬁnes for INT_ADC? (the four sample sequence interrupts for ADC0) have been deprecated

in favor of INT_ADC0SS?. This makes them consistent with the sample sequence interrupt deﬁnes

for ADC1, which are INT_ADC1SS?.

10.4 New Features in Stellaris Graphics Librar y

10.4.1 Added monospace font support to ftrasterize (Reference 10690)

Support has been added to ftrasterize to render a font with uniform spacing (in other words, a

monospaced font). Additionally, renderings of the Computer Modern monospaced font in sizes 12

through 48 have been added to the default font collection for the Stellaris Graphics Library.
