Method: OpenC3::CcsdsPacket#initialize

Defined in:
lib/openc3/ccsds/ccsds_packet.rb

#initialize(target_name = nil, packet_name = nil, include_ccsds_data = true) ⇒ CcsdsPacket

Creates a CCSDS packet by setting the target and packet name and then defining all the fields in a CCSDS packet with a primary header. If a secondary header is desired, define a secondary header field and then override the CcsdsData field to start after bit offset 48.

Parameters:

  • target_name (String) (defaults to: nil) —

    The target name

  • packet_name (String) (defaults to: nil) —

    The packet name
