# Message definitions for the ArduPilot Mega binary communications protocol.
#
# Process this file using:
#
# awk -f protogen.awk protocol.def > protocol.h
#
# Messages are declared with
#
#     message <MESSAGE_ID> <MESSAGE_NAME>
#
#       <MESSAGE_NAME> is a valid member of BinComm::MessageID.
#       <MESSAGE_ID> is the message ID byte
#
# Following a message declaration the fields of the message are
# defined in the format:
#
#    <TYPE> <NAME> [<COUNT>]
#
#       <TYPE> is a C type corresponding to the field.  The type must be a single
#       word, either an integer from <inttypes.h> or "char".
#	<NAME> is the name of the field; it should be unique within the message
#	<COUNT> is an optional array count for fields that are arrays
