The typical skeleton of the Custom DPA Handler looks like this (see CustomDpaHandler-Template-Node.c source code example for a complete template for Node):
// Default IQRF include
#include "IQRF.h"
// Uncomment to implement Custom DPA Handler for Coordinator
//#define COORDINATOR_CUSTOM_HANDLER
// Default DPA header
#include "DPA.h"
// Default Custom DPA Handler header
#include "DPAcustomHandler.h"
// Real Custom DPA Handler function
bit CustomDpaHandler ()
{
// Handler presence mark
clrwdt();
// Detect DPA event to handle
switch ( GetDpaEvent() )
{
case DpaEvent_Interrupt:
// …
return Carry;
// Other events …
case DpaEvent_Idle:
// …
return Carry;
case DpaEvent_DpaRequest:
if ( IsDpaEnumPeripheralsRequest() )
// Enumerate Peripherals
{
// …
return TRUE;
}
else if ( IsDpaPeripheralInfoRequest() )
// Get Peripheral Info
{
// …
return TRUE;
}
else
// Peripheral Request
{
// …
return TRUE;
}
}
return FALSE;
}
// Default Custom DPA Handler header
// (2nd include implementing a Code bumper to detect too long code of the handler)
#include "DPAcustomHandler.h"
