Use-case Analysis Presentations¶

• Stefan
  • Spread cross-compiling does not work well
  • RSC more fine-grained because one single library to load wastes memory
    • build all smaller libs with one CMake but configure via options what is required
  • Make tests and spread binary finding optional in RSB
  • How to map CAN messages to RSB messages (Shadow Hand uses a more complicated protocol than Stefan's robot)
  • Performance requirements:
    • 1 Mbit on the CAN bus
    • Marshaling could waste CPU
  • Robert and Stefan will further discuss what is required to build a more or less generic CAN ti RSB bridge
• Florian
  • Sending and receiving in a gstreamer pipeline using RSB
  • Audio missing
  • Overview about available classes
  • nearly easier than XCF
• Christoph
  • high-level data, IPC
    • how to use or define common types for this (type-safety vs. flexibility)
      • Frederic: e.g. starting from BTL and ROS messages
      • make a publicly available repository that is visible
    • migration path from XCF
  • video
    • for one computer there's a shared memory solution existing (later to be ported)
    • common types for images as protocol
      • support compression (e.g. run-length coding)
    • avoid extensions to this type(?)
• Robert
• Johannes/Jan
  • Conditional Sending (see above)
    • Problem statement and requirements
    • Implementation Plan
  • Inter-Segment Communication
    • Clarification
    • Documentation: wiki page

Additional Topics¶

• XCF Migration
  • CTU compatibility layer
  • Active Memory
