/**
|
|
* \file Common structs used between linux and the STM32 dev board. Data
|
|
* will be sent raw over the UDP socket, with the sender using
|
|
* \ref send(struct, sizeof(CbStruct))
|
|
* and the receiver using
|
|
* \ref receive(raw_bytes, sizeof(CbStruct))
|
|
* CbStruct *struct = reinterpret_cast<CbStruct *>(raw_bytes);
|
|
*
|
|
* Notes:
|
|
* 1) After V1 structs will not be able to remove fields, only add fields
|
|
* after the existing fields
|
|
* 2) There can be problems with variable length structs, for example
|
|
* CbFirmwarePacket that can have a payload with lengths 0-1024
|
|
*
|
|
* Test files are added at the end that check the sizes of the structs
|
|
* at compile time, to determine the fact that they are consistent
|
|
* across platforms.
