- *
- * \section Sec_HIDParser_Dependencies Module Source Dependencies
- * The following files must be built with any user project that uses this module:
- * - LUFA/Drivers/USB/Class/Host/HIDParser.c <i>(Makefile source module name: LUFA_SRC_USB)</i>
- *
- * \section Sec_HIDParser_ModDescription Module Description
- * Human Interface Device (HID) class report descriptor parser. This module implements a parser than is
- * capable of processing a complete HID report descriptor, and outputting a flat structure containing the
- * contents of the report in an a more friendly format. The parsed data may then be further processed and used
- * within an application to process sent and received HID reports to and from an attached HID device.
- *
- * A HID report descriptor consists of a set of HID report items, which describe the function and layout
- * of data exchanged between a HID device and a host, including both the physical encoding of each item
- * (such as a button, key press or joystick axis) in the sent and received data packets - known as "reports" -
- * as well as other information about each item such as the usages, data range, physical location and other
- * characteristics. In this way a HID device can retain a high degree of flexibility in its capabilities, as it
- * is not forced to comply with a given report layout or feature-set.
- *
- * This module also contains routines for the processing of data in an actual HID report, using the parsed report
- * descriptor data as a guide for the encoding.
