Header definitions for a FreeRTOS ringbuffer object
A ringbuffer instantiated by these functions essentially acts like a FreeRTOS queue, with the
difference that it's strictly FIFO and with the main advantage that you can put in randomly-sized
items. The capacity, accordingly, isn't measured in the amount of items, but the amount of memory
that is used for storing the items. Dependent on the size of the items, more or less of them will
fit in the ring buffer.
This ringbuffer tries to be efficient with memory: when inserting an item, the item data will
be copied to the ringbuffer memory. When retrieving an item, however, a reference to ringbuffer
memory will be returned. The returned memory is guaranteed to be 32-bit aligned and contiguous.
The application can use this memory, but as long as it does, ringbuffer writes that would write
to this bit of memory will block.
The requirement for items to be contiguous is slightly problematic when the only way to place
the next item would involve a wraparound from the end to the beginning of the ringbuffer. This can
be solved (or not) in a few ways:
- type = RINGBUF_TYPE_ALLOWSPLIT: The insertion code will split the item in two items; one which fits
in the space left at the end of the ringbuffer, one that contains the remaining data which is placed
in the beginning. Two xRingbufferReceive calls will be needed to retrieve the data.
- type = RINGBUF_TYPE_NOSPLIT: The insertion code will leave the room at the end of the ringbuffer
unused and instead will put the entire item at the start of the ringbuffer, as soon as there is
enough free space.
- type = RINGBUF_TYPE_BYTEBUF: This is your conventional byte-based ringbuffer. It does have no
overhead, but it has no item contiguousness either: a read will just give you the entire written
buffer space, or the space up to the end of the buffer, and writes can be broken up in any way
possible. Note that this type cannot do a 2nd read before returning the memory of the 1st.
The maximum size of an item will be affected by this decision. When split items are allowed, it's
acceptable to push items of (buffer_size)-16 bytes into the buffer. When it's not allowed, the
maximum size is (buffer_size/2)-8 bytes. The bytebuf can fill the entire buffer with data, it has
no overhead.

/**
* Creates a new software timer instance, and returns a handle by which the
* created software timer can be referenced.
*
* Internally, within the FreeRTOS implementation, software timers use a block
* of memory, in which the timer data structure is stored. If a software timer
* is created using xTimerCreate() then the required memory is automatically
* dynamically allocated inside the xTimerCreate() function. (see
* http://www.freertos.org/a00111.html). If a software timer is created using
* xTimerCreateStatic() then the application writer must provide the memory that
* will get used by the software timer. xTimerCreateStatic() therefore allows a
* software timer to be created without using any dynamic memory allocation.
*
* Timers are created in the dormant state. The xTimerStart(), xTimerReset(),
* xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
* xTimerChangePeriodFromISR() API functions can all be used to transition a
* timer into the active state.
*
* @param pcTimerName A text name that is assigned to the timer. This is done
* purely to assist debugging. The kernel itself only ever references a timer
* by its handle, and never by its name.
*
* @param xTimerPeriodInTicks The timer period. The time is defined in tick
* periods so the constant portTICK_PERIOD_MS can be used to convert a time that
* has been specified in milliseconds. For example, if the timer must expire
* after 100 ticks, then xTimerPeriodInTicks should be set to 100.
* Alternatively, if the timer must expire after 500ms, then xPeriod can be set
* to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
* equal to 1000.
*
* @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
* expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
* If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
* enter the dormant state after it expires.
*
* @param pvTimerID An identifier that is assigned to the timer being created.
* Typically this would be used in the timer callback function to identify which
* timer expired when the same callback function is assigned to more than one
* timer.
*
* @param pxCallbackFunction The function to call when the timer expires.
* Callback functions must have the prototype defined by TimerCallbackFunction_t,
* which is "void vCallbackFunction( TimerHandle_t xTimer );".
*
* @param pxTimerBuffer Must point to a variable of type StaticTimer_t, which
* will be then be used to hold the software timer's data structures, removing
* the need for the memory to be allocated dynamically.
*
* @return If the timer is created then a handle to the created timer is
* returned. If pxTimerBuffer was NULL then NULL is returned.
*
* Example usage:
* @code{c}
*
* // The buffer used to hold the software timer's data structure.
* static StaticTimer_t xTimerBuffer;
*
* // A variable that will be incremented by the software timer's callback
* // function.
* UBaseType_t uxVariableToIncrement = 0;
*
* // A software timer callback function that increments a variable passed to
* // it when the software timer was created. After the 5th increment the
* // callback function stops the software timer.
* static void prvTimerCallback( TimerHandle_t xExpiredTimer )
* {
* UBaseType_t *puxVariableToIncrement;
* BaseType_t xReturned;
*
* // Obtain the address of the variable to increment from the timer ID.
* puxVariableToIncrement = ( UBaseType_t * ) pvTimerGetTimerID( xExpiredTimer );
*
* // Increment the variable to show the timer callback has executed.
* ( *puxVariableToIncrement )++;
*
* // If this callback has executed the required number of times, stop the
* // timer.
* if( *puxVariableToIncrement == 5 )
* {
* // This is called from a timer callback so must not block.
* xTimerStop( xExpiredTimer, staticDONT_BLOCK );
* }
* }
*
*
* void main( void )
* {
* // Create the software time. xTimerCreateStatic() has an extra parameter
* // than the normal xTimerCreate() API function. The parameter is a pointer
* // to the StaticTimer_t structure that will hold the software timer
* // structure. If the parameter is passed as NULL then the structure will be
* // allocated dynamically, just as if xTimerCreate() had been called.
* xTimer = xTimerCreateStatic( "T1", // Text name for the task. Helps debugging only. Not used by FreeRTOS.
* xTimerPeriod, // The period of the timer in ticks.
