DEMO 3: How to display a register on a panel

A simple example to illustrate how a monitored register can be displayed on a panel

  (...)


 // Code to be inserted under 'EventInitialize'   
  
  main()
{
   string dp;                                            // if a device unit calls a panel the $2 parameter can be passed holding         
   dp = $2 + ".SL.REALTIME.TtcResetSigCntReg.readings";  // the device unit's datapoint
                                                         // the datapoint element 'readings' is where the monitoring service is updated
   if (dpConnect("callback", dp) == 0)
      DebugTN("Connected datapoint: " + dp);             // dpConnect: whenever the datapoint element changes the callback function is called
   else
      DebugTN("Error in dpConnect for " + dp + " in panel 'Overview'!!!"); }

callback(string dp, dyn_char readings){
   //DebugTN(readings);
   string dummy;
   dummy = fwCcpc_convertByteToHex(readings);            // the data is represented as a byte stream (LBUS), so it has to be converted
                                                         // into a hexadecimal string to be represented in a text widget
   
   TtcResetSigCntReg2.text = "0x" + dummy;               // printing the string to the text widget
   
   //TtcResetSigCntReg2.text = "0x" + fwTell1_BitsFromString(dummy,15,8);
                                                         // in the fwTell1 framework functions are provided to cut a bit-array out of
                                                         // a register and represent the 'sub-register' as string or integer.
