Primitive (Animation)


Description

The Primitive task handles "trigger primitive" messages from the spacecraft, providing emergency access to low-level hardware interfaces in the LAT instrument.

The task supports two data paths:

  • Spacecraft

    The Spacecraft sends a command packet to the task, which forwards it to the LAT Instrument. The task then forwards the LAT's response to the Spacecraft.

  • Task

    A client Task sends a command packet to the Primitive task, which forwards it to the LAT Instrument. The Primitive task then forwards the LAT's response to the client Task.
