NAME
UAV::Pilot::ArdupilotProtocol::PacketDESCRIPTION
Role for ArdupilotProtocol packets. These are based on the ArduPilot protocol packets, as described here:
http://code.google.com/p/ardupilot-mega/wiki/Protocol
No attempts have yet been made to test this against an existing ArduPilot implmentation, but it should be close.
Do not create Packets directly. Instead, use UAV::Pilot::ArdupilotProtocol::PacketFactory.
Does the UAV::Pilot::Logger role.
METHODS
write
write( $fh )Writes the packet to the given filehandle.
make_checksum_clean
Recalculates the checksum based on current field values.
make_byte_vector
Returns the packet fields in a single scalar full of bytes.
get_ordered_payload_vales
Returns the packet field values in the order they appear in payload_fields().
get_ordered_payload_value_bytes
Returns a byte array of all the packet fields in the order they appear in payload_fields().
make_packet_queue_map_key
Creates a unique key for this packet.
ATTRIBUTES
preamble
Fixed bytes that start every packet
