/**
|
|
* @brief An interface for alle classes which require
|
|
* translation of objects data into data streams and vice-versa.
|
|
* @details
|
|
* If the target architecture is little endian (e.g. ARM), any data types created might
|
|
* have the wrong endiness if they are to be used for the FSFW.
|
|
* There are three ways to retrieve data out of a buffer to be used in the FSFW to use
|
|
* regular aligned (big endian) data. This can also be applied to uint32_t and uint64_t:
|
|
*
|
|
* 1. Use the @c AutoSerializeAdapter::deSerialize function with @c bigEndian = true
|
|
* 2. Perform a bitshift operation
|
|
* 3. @c memcpy can be used when data is in little-endian format. Otherwise, @c EndianSwapper has to be used in conjuction.
|
|
*
|
|
* When serializing for downlink, the packets are generally serialized assuming big endian data format
|
|
* like seen in TmPacketStored.cpp for example.
