Detailed Description

GASU counter acquisition (both GEM and EBM, via LRA).

CVS $Id: LIH_GasuCounts.c,v 1.2 2007/12/07 03:59:21 apw Exp $

Author:

A.P.Waite

LIH_GasuCounts.c provides a housekeeping interface to capture the the GEM and EBM counters. The counters are physically read (and extended into to 8-byte counters) by the LRA task. This function simply sponges off all the hard work already done by LRA.

Function Documentation

static LHK_PacketStatus LIH_captureGasuCounts (  unsigned char *  prm, unsigned int  abas, unsigned int  aidx, unsigned int  seq, unsigned char *  out )  [static]

Capture CPU "top" records into housekeeping/diagnostic packets. Parameters: prm  (in) User parameter (not used) 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 LIH_defineGasuCounts (  void   )

Initialize capture of GASU counters (GEM and EBM). Return values: LHK_GENERROR  Generic error LHK_SUCCESS  Success LIH_defineGasuCounts() initializes any necessary resources to capture "GasuCounts" packets, and puts the handler definition in the packet table.
