  • event - event function that is called when the response is received

Return Value

Remarks

The application must have a background event that calls MnBdRead to facilitate this.

Examples

SetBackgroundEvent(BackgroundEventComm);

MnBdSetEvent(MNBD_REQ_GET_WT, MnBdEventWtRcv);

...

MNBD_EVENT(WtRcv)
{
   if(IsGrossWtChanged(1))
   {
      DisplayText(0, 40, GetChangedGrossWt(1), 0, BIG_FONT);
   }
   return 0;
}

BACKGROUND_EVENT(Comm)
{
	// Use MnBdRead directly to prevent overhead of MnBdProcess

	int n;
	// in case we have more I/O cards than scales change this
	for(n = 0; n <= GetNumScales(); n++)
	{
		// 0 = MNBD_DEV, 1 .. Scales and I/O cards
		MnBdRead(n);
	}

   if(timerReqWeigt.IsExpired() == true)
   { 
      MnBdRequest(1, MNBD_REQ_GET_WT, NO_WAIT_ACK);
   }
return 0;
}
