Removed SerialStream module, rolled functionality into the base USART Serial peripheral driver instead through the new Serial_CreateStream() and Serial_CreateBlockingStream() methods.
Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions. Altered the serial byte receive function to make it non-blocking.

* \section Sec_ModDescription Module Description
|
||||
* Functions, macros, variables, enums and types related to the parsing of HID class device report descriptors.
|
||||
* 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.
|
||||
*
|
||||
* The processed HID report is presented back to the user application as a flat structure containing each report
|
||||
* item's IN, OUT and FEATURE items along with each item's attributes.
|
||||
* 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
|
||||
* characterstics. 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 featureset.
|
||||
*
|
||||
* This library portion also allows for easy setting and retrieval of data from a HID report, including devices
|
||||
* with multiple reports on the one HID interface.
|
||||
* This module also contains routines for the processing of data in an actual HID report, using the parsed report
|
||||
* descritor data as a guide for the encoding.
