Detailed Description

Structure returned by the Parser::update() function.

The ParserReturn::hdr values are only valid in these situations:

res	hdr
INSUFFICIENT_DATA	Valid
RECEIVED_INVALID_HEADER	Valid
RECEIVED_SYS_ACK	Valid
RECEIVED_SYS_NACK	Valid
RECEIVED_CMD_SELECT	Valid
RECEIVED_CMD_WRITE	Valid
RECEIVED_CMD_INVALID_FCS	Valid

The ParserReturn::len values can be interpreted this way:

res	len
INSUFFICIENT_DATA	No meaning
RECEIVED_INVALID_HEADER	No meaning
RECEIVED_SYS_ACK	No meaning
RECEIVED_SYS_NACK	No meaning
RECEIVED_CMD_SELECT	Length of the SELECT message's payload (1 byte)
RECEIVED_CMD_WRITE	Length of the WRITE message's payload
RECEIVED_CMD_INVALID_FCS	Length of the payload with invalid FCS
