§ USBShort

#define USBShort ( ui16Value ) (ui16Value & 0xff), (ui16Value >> 8)

Write a 16-bit value to a USB descriptor block.

Parameters

ui16Value is the 16-bit value to write to the descriptor.

This helper macro is used in descriptor definitions to write two-byte values. Since the configuration descriptor contains all interface and endpoint descriptors in a contiguous block of memory, these descriptors are typically defined using an array of bytes rather than as packed structures.

Returns: Not a function.

§ USB3Byte

#define USB3Byte ( ui32Value )

Value:

(ui32Value & 0xff),                           \
                                ((ui32Value >> 8) & 0xff),                    \
                                ((ui32Value >> 16) & 0xff)

Write a 24-bit value to a USB descriptor block.

Parameters

ui32Value is the 24-bit value that to write to the descriptor.

This helper macro is used in descriptor definitions to write three-byte values. Since the configuration descriptor contains all interface and endpoint descriptors in a contiguous block of memory, these descriptors are typically defined using an array of bytes rather than as packed structures.

Returns: Not a function.

§ USBLong

#define USBLong ( ui32Value )

Value:

(ui32Value & 0xff),                           \
                                ((ui32Value >> 8) & 0xff),                    \
                                ((ui32Value >> 16) & 0xff),                   \
                                ((ui32Value >> 24) & 0xff)

Write a 32-bit value to a USB descriptor block.

Parameters

ui32Value is the 32-bit value that to write to the descriptor.

This helper macro is used in descriptor definitions to write four-byte values. Since the configuration descriptor contains all interface and endpoint descriptors in a contiguous block of memory, these descriptors are typically defined using an array of bytes rather than as packed structures.

Returns: Not a function.

§ NEXT_USB_DESCRIPTOR

#define NEXT_USB_DESCRIPTOR ( ptr )

Value:

(tDescriptorHeader *)(((uint8_t *)(ptr)) + \

*((uint8_t *)(ptr)))

Traverse to the next USB descriptor in a block.

Parameters

ptr	points to the first byte of a descriptor in a block of USB descriptors.

This macro aids in traversing lists of descriptors by returning a pointer to the next descriptor in the list given a pointer to the current one.

Returns: Returns a pointer to the next descriptor in the block following ptr.
