* @details
|

* List of control codes:
|
||||
* https://en.wikipedia.org/wiki/C0_and_C1_control_codes
|
||||
*
|
||||
* This encoder can be used to achieve a basic transport layer when using
|
||||
* char based transmission systems.
|
||||
* The passed source strean is converted into a encoded stream by adding
|
||||
* a STX marker at the start of the stream and an ETX marker at the end of
|
||||
* the stream. Any STX, ETX, DLE and CR occurrences in the source stream are
|
||||
* escaped by a DLE character. The encoder also replaces escaped control chars
|
||||
* by another char, so STX, ETX and CR should not appear anywhere in the actual
|
||||
* encoded data stream.
|
||||
*
|
||||
* When using a strictly char based reception of packets encoded with DLE,
|
||||
* STX can be used to notify a reader that actual data will start to arrive
|
||||
* while ETX can be used to notify the reader that the data has ended.

* message queue messages.
|
||||
* @details
|
||||
* Message queues are used to pass asynchronous messages between processes.
|
||||
* They work like post boxes, where all incoming messages are stored in FIFO
|
||||
* order. This class creates a new receiving queue and provides methods to fetch
|
||||
* received messages. Being a child of MessageQueueSender, this class also
|
||||
* provides methods to send a message to a user-defined or a default destination.
|
||||
* In addition it also provides a reply method to answer to the queue it
|
||||
* received its last message from.
|
||||
*
|
||||
* The MessageQueue should be used as "post box" for a single owning object.
|
||||
* So all message queue communication is "n-to-one".
|
||||
* For creating the queue, as well as sending and receiving messages, the class
|
||||
* makes use of the operating system calls provided.
|
||||
*
|
||||
* Please keep in mind that FreeRTOS offers different calls for message queue
|
||||
* operations if called from an ISR.
|
||||
* For now, the system context needs to be switched manually.
