Detailed Description

Extra datalink and telemetry using PPRZ protocol.

NOTES (for future reference): This note is not needed unless we want to define our own messages - in such case you would define the two structs below and then define individual messages and registered them in the same way as periodic telemetry. struct telemetry_cb_slots telemetry_cbs_logger[TELEMETRY_PPRZ_NB_MSG] = TELEMETRY_PPRZ_CBS; struct periodic_telemetry logger_telemetry = { TELEMETRY_PPRZ_NB_MSG, telemetry_cbs_logger };

The registration should be done in the init function: register_periodic_telemetry(&extra_telemetry, PPRZ_MSG_ID_xxx, send_xxx_message);

Two extra notes for the periodic function: 1) this sends registered messages from ExtraTelemetry process (as mentioned above) over dedicated port do: periodic_telemetry_send_ExtraTelemetry(&extra_telemetry, &pprz_tp_extra.trans_tx, &(EXTRA_TELEMETRY_PORT).device); 2) to send ExtraTelemetry messages over default channel just change to: periodic_telemetry_send_ExtraTelemetry(DefaultPeriodic, &(DefaultChannel).trans_tx, &(DefaultDevice).device);
