Function Documentation

static LHK_PacketStatus capture (  unsigned int *  sav, unsigned int  abas, unsigned int  aidx, unsigned int  seq, unsigned char *  out )  [static]

Copy hardware monitoring housekeeping packets from packet database. Parameters: sav  (in) User parameter (update counter of last packet copy) abas  (in) Base of APID table (ITC_K_APID_HOUSE or ITC_K_APID_DIAG) aidx  (in) APID index seq  (in) CCSDS sequence count out  (in) Output buffer (beginning of CCSDS telemetry header) Returns: A member of the LIH_PacketStatus enumeration

static unsigned int control_rx (  void *  prm, const ITC_QueueItem *  qitem, void *  pay, unsigned int  len )  [static]

Process messages arriving on the control queue. Parameters: prm  (in) User context parameter qitem  (in) Queue item to process pay  (in) Queue item payload len  (in) Queue item payload length control_rx() is the callback routine for any raw protocol ITC traffic arriving on the control queue. For now, there is no such traffic, and this routine is a NOOP.

static WUT_cb_status expireTimer (  void *  prm, WUT_tmr *  tmr )  [static]

Timer callback routine (called at interrupt level). Parameters: prm  (in) User parameter (harware monitoring control block) tmr  (in) Wake up timer handle expireTimer() is a timer callback routine. It simply wakes up the harware monitoring task.

static FORK_cb_status forkTimer (  FORK_cb_prm *  prm, FORK_msg_hdr *  hdr )  [static]

Task level target of the cyclic interrupt timer. Parameters: prm  (in) FORK parameter (not used) (cannot be used!) hdr  (in) The fork message (not used) forkTimer() drives the cyclic hardware monitoring functions.

static unsigned int initializeAcq (  LIH_Control *  hcb, LIH_DB_Schema *  ldb )  [static]

Initialize the hardware acquisition facilities. Parameters: hcb  (in) LIH hardware monitoring control block ldb  (in) LIH data handle (from CDM) initializeAcq() builds up the LIH hardware mmonitoring acquisition facilities.

static unsigned int initializeLCB (  LIH_Control *  hcb, LIH_DB_Schema *  ldb )  [static]

Initialize the LCB controls. Parameters: hcb  (in) LIH hardware monitoring control block ldb  (in) LIH data handle (from CDM) initializeLCB() initializes the LCB controls

static unsigned int initializeLimits (  LIH_Control *  hcb, LIH_DB_Schema *  ldb )  [static]

Initialize the ADC limit monitoring controls. Parameters: hcb  (in) LIH hardware monitoring control block ldb  (in) LIH data handle (from CDM) initializeLimits() initializes the ADC limit checking system

static unsigned int initializeTask (  LIH_Control *  hcb, LIH_DB_Schema *  ldb )  [static]

Initialize the LIH hardware monitoring task. Parameters: hcb  (in) LIH hardware monitoring control block ldb  (in) LIH data handle (from CDM) initializeTask() builds up the LIH hardware monitoring task.

unsigned int LIH_initialize (   )

Initialize the LIH hardware monitoring facility. LIH_initialize() does all the initialization required by the hardware monitoring facilities in LIH.

unsigned int LIH_start (   )

Start the LIH hardware monitoring task. LIH_start() starts the LIH hardware monitoring task
