Function Documentation

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 traffic arriving on the control queue. For now, that's CPU status records and ITC configuration records coming from the EPUs.

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

Copy housekeeping packets from the LCM 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 LHK_PacketStatus enumeration

unsigned int LCM_houseInitializeSIU

(

LCM_Control *

ctl

)

Initialize the housekeeping function (specific to SIU).

Parameters:

ctl

(in) LCM control block

LCM_houseInitializeSIU() builds up the SIU specific elements for providing housekeeping information.
