Detailed Description

Periodic telemetry system header (includes downlink utility and generated code).

In order to use it a subsystem/module:

  • include this header:
  • write a callback function:
    void your_callback(void) {
    // your code to send a telemetry message goes here
  • register your callback function (if the message name doesn't match one of the names in your telemetry xml file or is already registered, the function return FALSE)
    register_periodic_telemetry(&your_telemetry_struct, DL_<YOUR_MESSAGE_NAME>, your_callback);
    In most cases, the default telemetry structure should be used (replace &your_telemetry_struct by DefaultPeriodic in the register function).
