Function Documentation

HPI_ERR HPI_Bitstream_GetActivity (  HPI_HSUBSYS *  phSubSys, HPI_HCONTROL  hControl, HW16 *  pwClkActivity, HW16 *  pwDataActivity )

Returns 2 indicative measurements of the incoming data stream. The clock input is deemed inactive if no data bytes are received within a certain number of calls to a polling routine. The time this takes varies according to the number of active streams. If there is clock activity, the data activity indicator is a sample of 16 bits from the incoming data. If this is persistently 0 or 0xFFFF, this may indicate that the data input is inactive. Returns: 0 on success, or one of the HPI Error codes. Parameters: phSubSys  Subsystem handle hControl  Handle to bitstream control pwClkActivity  1==clock is active, 0==clock is inactive pwDataActivity  1 word sampled from the incoming raw data
