Detailed Description

Mission Computer module, interfacing the mission computer (also known as Copilot), based losely on ISaAC: The Intelligent Safety and Airworthiness Co-Pilot module Based on paper "A Payload Verification and Management Framework for Small UAV-based Personal Remote Sensing Systems" by Cal Coopmans and Chris Coffin.

More info can be found on http://wiki.paparazziuav.org/wiki/Mission_computer

Copilot is intended mainly for mapping applications.

This module processes messages from Copilot, and either forwards them to the GCS (such as CAMERA_SNAPSHOT or CAMERA_PAYLOAD messages), or responds to them as necessary (such as MOVE_WP).

The module assumes the source of the messages is trusted (i.e. not authentication besides AC_ID check is performed).

Function Documentation

void copilot_init ( void )

Init function.

References cam_payload, cam_snapshot, copilot_status, PPRZ_MUTEX_INIT, send_cam_payload, send_cam_snapshot, and send_copilot_status.

void copilot_parse_cam_payload_dl ( uint8_t * buf )

copy CAMERA_PAYLOAD message and mark it to be sent

Definition at line 147 of file copilot_common.c.

void copilot_parse_cam_snapshot_dl ( uint8_t * buf )

Message processing functions.

In case of multiple cameras, it is up to the payload computer to send CAMERA_SNAPSHOT messages for each camera at proper interval, so the values don't get overwritten.
