Subtopology Telemetry

Subtopology that instantiates a local tlmSend that depends on the Svc::TlmPacketizer component.

Utilizes the F Prime Subtopology autocoder.

Instantiation

In your main deployment module, in topology.fpp, add the following:

topology Tlm {}
@<! is Telemetry.Telemetry base id 0x1111

Then, in the main deployment topology, in topology.fpp, add the following:

import Tlm
instance Telemetry.Input # input interface
instance Telemetry.Output # output interface

Lastly, we want to add our interface connection graph, like so:

connections Interface_Tlm {
    rateGroup1.RateGroupMemberOut[0] -> Telemetry.Input.Run
    Telemetry.Output.PktSend_out -> comQueue.comQueueIn[1]
}

Utilization

See the pdd.md for how to get the fillables for the config objects. Get the outputs of them by running fppm config --apply mosallaei/TlmPacketizer. Then:

• Telemetry.fpp needs to be moved into a module and added to a source list.
• TopologyDefs.hpp needs to be moved into the Top/ folder of your main deployment
• Packets.xml needs to be moved into the Top/ folder of your main deployment
