* @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)
|

|

* 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

|

* An event group is a collection of bits to which an application can assign a
|

* meaning. For example, an application may create an event group to convey
|
||||
* the status of various CAN bus related events in which bit 0 might mean "A CAN
|
||||
* message has been received and is ready for processing", bit 1 might mean "The
|
||||
* application has queued a message that is ready for sending onto the CAN
|
||||
* network", and bit 2 might mean "It is time to send a SYNC message onto the
|
||||
* CAN network" etc. A task can then test the bit values to see which events
|
||||
* are active, and optionally enter the Blocked state to wait for a specified
|
||||
* bit or a group of specified bits to be active. To continue the CAN bus
|

* example, a CAN controlling task can enter the Blocked state (and therefore
|
||||
* not consume any processing time) until either bit 0, bit 1 or bit 2 are
|
||||
* active, at which time the bit that was actually active would inform the task
|
||||
* which action it had to take (process a received message, send a message, or
|
||||
* send a SYNC).
|
||||
*
|
||||
* The event groups implementation contains intelligence to avoid race
|

* conditions that would otherwise occur were an application to use a simple

* variable for the same purpose. This is particularly important with respect

* to when a bit within an event group is to be cleared, and when bits have to

|
||||
* Message buffers build functionality on top of FreeRTOS stream buffers.
|
||||
* Whereas stream buffers are used to send a continuous stream of data from one
|
||||
* task or interrupt to another, message buffers are used to send variable
|
||||
* length discrete messages from one task or interrupt to another. Their
|
||||
* implementation is light weight, making them particularly suited for interrupt
|
||||
* to task and core to core communication scenarios.
|
||||
*
|
||||
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
|
||||
* implementation (so also the message buffer implementation, as message buffers
|
||||
* are built on top of stream buffers) assumes there is only one task or
|
||||
* interrupt that will write to the buffer (the writer), and only one task or
|
||||
* interrupt that will read from the buffer (the reader). It is safe for the
|
||||
* writer and reader to be different tasks or interrupts, but, unlike other
|
||||
* FreeRTOS objects, it is not safe to have multiple different writers or
|
||||
* multiple different readers. If there are to be multiple different writers
|
||||
* then the application writer must place each call to a writing API function
|
||||
* (such as xMessageBufferSend()) inside a critical section and set the send
|
||||
* block time to 0. Likewise, if there are to be multiple different readers
|
||||
* then the application writer must place each call to a reading API function
|
||||
* (such as xMessageBufferRead()) inside a critical section and set the receive
|
||||
* timeout to 0.
|
||||
*
|
||||
* Message buffers hold variable length messages. To enable that, when a
|
||||
* message is written to the message buffer an additional sizeof( size_t ) bytes
|
||||
* are also written to store the message's length (that happens internally, with
|
||||
* the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit
|
||||
* architecture, so writing a 10 byte message to a message buffer on a 32-bit
|
||||
* architecture will actually reduce the available space in the message buffer
|
||||
* by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
|
||||
* of the message).

If you find your application is crashing here then likely causes are

more tips, and ensure configASSERT() is defined!
|
||||
http://www.freertos.org/a00110.html#configASSERT
|
||||
|
||||
1) Stack overflow -
|
||||
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
|
||||
2) Incorrect interrupt priority assignment, especially on Cortex-M
|
||||
parts where numerically high priority values denote low actual
|
||||
interrupt priorities, which can seem counter intuitive. See
|
||||
http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
|
||||
of configMAX_SYSCALL_INTERRUPT_PRIORITY on
|
||||
http://www.freertos.org/a00110.html
|
||||
3) Calling an API function from within a critical section or when
|
||||
the scheduler is suspended, or calling an API function that does
|
||||
not end in "FromISR" from an interrupt.
|
||||
4) Using a queue or semaphore before it has been initialised or
|
||||
before the scheduler has been started (are interrupts firing
|
||||
before vTaskStartScheduler() has been called?).

/*
|
||||
* A sample implementation of pvPortMalloc() that allows the heap to be defined
|
||||
* across multiple non-contigous blocks and combines (coalescences) adjacent
|
||||
* memory blocks as they are freed.
|
||||
*
|
||||
* See heap_1.c, heap_2.c, heap_3.c and heap_4.c for alternative
|
||||
* implementations, and the memory management pages of http://www.FreeRTOS.org
|
||||
* for more information.
|
||||
*
|
||||
* Usage notes:
|
||||
*
|
||||
* vPortDefineHeapRegions() ***must*** be called before pvPortMalloc().
|
||||
* pvPortMalloc() will be called if any task objects (tasks, queues, event
|
||||
* groups, etc.) are created, therefore vPortDefineHeapRegions() ***must*** be
|
||||
* called before any other objects are defined.
|
||||
*
|
||||
* vPortDefineHeapRegions() takes a single parameter. The parameter is an array
|
||||
* of HeapRegion_t structures. HeapRegion_t is defined in portable.h as
|
||||
*
|
||||
* typedef struct HeapRegion
|
||||
* {
|
||||
* uint8_t *pucStartAddress; << Start address of a block of memory that will be part of the heap.
|
||||
* size_t xSizeInBytes; << Size of the block of memory.
|
||||
* } HeapRegion_t;
|
||||
*
|
||||
* The array is terminated using a NULL zero sized region definition, and the
|
||||
* memory regions defined in the array ***must*** appear in address order from
|
||||
* low address to high address. So the following is a valid example of how
|
||||
* to use the function.
|
||||
*
|
||||
* HeapRegion_t xHeapRegions[] =
|
||||
* {
|
||||
* { ( uint8_t * ) 0x80000000UL, 0x10000 }, << Defines a block of 0x10000 bytes starting at address 0x80000000
|
||||
* { ( uint8_t * ) 0x90000000UL, 0xa0000 }, << Defines a block of 0xa0000 bytes starting at address of 0x90000000
|
||||
* { NULL, 0 } << Terminates the array.
|
||||
* };
|
||||
*
|
||||
* vPortDefineHeapRegions( xHeapRegions ); << Pass the array into vPortDefineHeapRegions().
|
||||
*
|
||||
* Note 0x80000000 is the lower address so appears in the array first.
