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. - * - * @{ - */ - -#ifndef __HIDPARSER_H__ -#define __HIDPARSER_H__ - - /* Includes: */ - #include "../../../../Common/Common.h" - - #include "HIDReportData.h" - #include "HIDClassCommon.h" - - /* Enable C linkage for C++ Compilers: */ - #if defined(__cplusplus) - extern "C" { - #endif - - /* Macros: */ - #if !defined(HID_STATETABLE_STACK_DEPTH) || defined(__DOXYGEN__) - /** Constant indicating the maximum stack depth of the state table.
