RJ10DLL::GetExtIQDrawData

float GetExtIQDrawData( IQ_DRAW_PARA *GetPara);

Return Value

    the value of max magnitude level

Parameters

   GetPara
   A pointer to the IQ_DRAW_PARA structure.
 

Remarks

   get for parorama viewer all the plot data and parameter of the current extern IQ-Complex-Signal.

   Note:
   if the Audio-Thread is running,
   then the routine sends a Message WM_GET_SPECTRUM
   every time a block of 2048 sample is ready.
   And that's the right time for this Command.
  

Example

ON_MESSAGE(WM_GET_SPECTRUM, OnIFInput)

wParam Bit-0 == normal IF- real signal input
wParam Bit-1 == normal IQ- complex signal input

LRESULT CRJ10MiniDlg::OnIFInput(WPARAM wParam, LPARAM lParam)
{
    //we use only every second view - the sequence is 48000/2048=23.4375 = ~23
  if(!StopFlag && myExtRxPara.IQ_open)
      {
      DrawDelaySum+=DrawInputFac;
      if(DrawDelaySum>=DrawDelayFac || DrawImmediately)
         {
         if(!DrawImmediately) DrawDelaySum-=DrawDelayFac;
         DrawImmediately=0;
         int chn=wParam&3; //wParam = (imax<<2|chn);
         int imax=wParam>>2;
         if(chn&1)
             {
             m_IFctrl.m_View.GetDrawData(); // 48000/2048 ~23 x per sec.
             m_inpeek.SetPeakMeter(imax);   // set input level
             }
         if(chn&2) m_IFctrl.myPanorama.m_View.GetDrawData(lParam);
         }
       }
  return NULL;
