Member Data Documentation

◆ crc8

uint8_t modules::protocol::RequestMsg::crc8

CRC8 check - please note we abuse this byte for CRC of ResponseMsgs as well. The crc8 byte itself is not added into the CRC computation (obviously ;) ) Beware - adding any members of this data structure may need changing the way CRC is being computed!

The documentation for this struct was generated from the following file:

src/modules/protocol.h
