Function Documentation

static void LCM_freeMsg (  ITC_QueueItem *  qitem, unsigned int  status, LCM_Control *  ctl, void *  prm1, void *  prm2 )  [static]

Free memory after sending MSG CTDB telemetry packets. Parameters: qitem  The memory buffer. status  Status of telemetry. ctl  LCM control structure. prm1  Completion callback paramter 1. prm2  Completion callback paramter 2.

static void LCM_freeMsgSSR (  ITC_QueueItem *  qitem, unsigned int  status, LCM_Control *  ctl, void *  prm1, void *  prm2 )  [static]

Free memory after sending MSG SSR telemetry packets. Parameters: qitem  The memory buffer. status  Status of telemetry. ctl  LCM control structure. prm1  Completion callback parameter 1. prm2  Completion callback parameter 2.

unsigned int LCM_messageInitialize (  LCM_Control *  ctl  )

Initialize the LCM message handling subsystem. Parameters: ctl  (in) LCM control block LCM_messageInitialize() builds up the CPU common facilities for sending messages to CTDB/SSR.

void LCM_msgAttachCTDB (  void   )

Setup MSG output callback for CTDB diagnostic telemetry. Attach LCM CTDB output callback.

void LCM_msgAttachSSR (  void   )

Setup MSG output callback for SSR science data telemetry. Attach LCM SSR science data output callback.

static WUT_cb_status LCM_msgDelay (  SEM  sem, WUT_tmr *  timer )  [static]

Timer callback for MSG send delay. Parameters: sem  The semaphore to release to indicate delay done. timer  The WUT handle for the timer. Returns: WUT_K_STATE_CHANGE_NO.

static void LCM_msgOutputCTDB (  MSG_OutputModes  mode, void *  prm, MSG_Message *  msg )  [static]

Output callback which packages each MSG record as a single CTDB diagnostic CCSDS telemetry packet. Parameters: mode  Current MSG control mode. prm  User parameter. msg  MSG output record to send.

static void LCM_msgOutputSSR (  MSG_OutputModes  mode, void *  prm, MSG_Message *  msg )  [static]

Output callback which packages each MSG record as a single LCM datagram wrapped by a CCSDS science data telemetry packet. Parameters: mode  Current MSG control mode. prm  User parameter. msg  MSG output record to send.

Variable Documentation

apidMap [static]

Initial value: { LCM_LCMMSGSSRSI_TLM_APID, LCM_LCMMSGSSRE0_TLM_APID, LCM_LCMMSGSSRE1_TLM_APID, LCM_LCMMSGSSRE2_TLM_APID, LCM_LCMMSGSSRE3_TLM_APID, } Array mapping ITC node ID's to SSR telemetry packet APID's.

LCM_severityXlat [static]

Initial value: { 0, 2, 1, 3 } Array mapping MSG severity codes into increasing levels.
