* An example that mimics a message buffer being used to pass data from one core
* to another. The core that sends the data is referred to as core A. The core
* that receives the data is referred to as core B. The task implemented by
* prvCoreATask() runs on core A. Two instances of the task implemented by
* prvCoreBTasks() run on core B. prvCoreATask() sends messages via message
* buffers to both instances of prvCoreBTasks(), one message buffer per channel.
* A third message buffer is used to pass the handle of the message buffer
* written to by core A to an interrupt service routine that is triggered by
* core A but executes on core B.
*
* The example relies on the FreeRTOS provided default implementation of
* sbSEND_COMPLETED() being overridden by an implementation in FreeRTOSConfig.h
* that writes the handle of the message buffer that contains data into the
* control message buffer, then generates an interrupt in core B. The necessary
* implementation is provided in this file and can be enabled by adding the
* following to FreeRTOSConfig.h:
*
* #define sbSEND_COMPLETED( pxStreamBuffer ) vGenerateCoreBInterrupt( pxStreamBuffer )
*
* Core to core communication via message buffer requires the message buffers
* to be at an address known to both cores within shared memory.
*
* Note that, while this example uses three message buffers, the same
* functionality can be implemented using a single message buffer by using the
* same design pattern described on the link below for queues, but using message
* buffers instead. It is actually simpler with a message buffer as variable
* length data can be written into the message buffer directly:
