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.
