/** ****************************************************************************** * @file usbd_cdc.c * @author MCD Application Team * @brief This file provides the high layer firmware functions to manage the * following functionalities of the USB CDC Class: * - Initialization and Configuration of high and low layer * - Enumeration as CDC Device (and enumeration for each implemented memory interface) * - OUT/IN data transfer * - Command IN transfer (class requests management) * - Error management * * @verbatim * * =================================================================== * CDC Class Driver Description * =================================================================== * This driver manages the "Universal Serial Bus Class Definitions for Communications Devices * Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus * Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007" * This driver implements the following aspects of the specification: * - Device descriptor management * - Configuration descriptor management * - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN) * - Requests management (as described in section 6.2 in specification) * - Abstract Control Model compliant * - Union Functional collection (using 1 IN endpoint for control) * - Data interface class * * These aspects may be enriched or modified for a specific user application. * * This driver doesn't implement the following aspects of the specification * (but it is possible to manage these features with some modifications on this driver): * - Any class-specific aspect relative to communication classes should be managed by user application. * - All communication classes other than PSTN are not managed * * @endverbatim * ****************************************************************************** * @attention * *
