[SOLVED] Edge Interrupt with PLIB.h on pic32 problems

[Ivan-Holm]

Hi we have some problem that this code

 [syntax=c]#include<p32xxxx.h>
#include<stdio.h>
#include <plib.h>

#pragma config FPLLMUL = MUL_20, FPLLIDIV = DIV_2, FPLLODIV = DIV_1, FWDTEN = OFF
#pragma config POSCMOD = HS, FNOSC = PRIPLL, FPBDIV = DIV_2

#define SYS_FREQ (80000000L)

#define CORE_TIMER_PERIOD       SYS_FREQ
//void ConfigInt0(EXT_INT_ENABLE |FALLING_EDGE_INT |EXT_INT_PRI_5 );
int Toggle_count;
int main()
{

void ConfigInt0(EXT_INT_ENABLE |FALLING_EDGE_INT | EXT_INT_PRI_5 );
TRISD =0x00000000;
PORTDbits.RD0 = 1;

while(1)
{
};
};


void __ISR(3, IPL5) CoreTimerHandler(void) //INT_EXTERNAL_0_VECTOR
{
   
//  .. things to do
	if (Toggle_count == 1) mPORTDToggleBits(BIT_0);
	if (Toggle_count == 2) mPORTDToggleBits(BIT_1);
	if (Toggle_count == 3) mPORTDToggleBits(BIT_2);
	Toggle_count ++;
	if (Toggle_count == 4) Toggle_count = 1;


	// .. Toggle the LED
 mPORTDToggleBits(BIT_0);

    // update the period
    UpdateCoreTimer(CORE_TIMER_PERIOD);

    // clear the interrupt flag
    mINT0ClearIntFlag();
while(1);
}[/syntax]

the error is in both void ConfigInt0 sentence when we have out-comment one at a time. we dont know if it is the right to do?. when we out-comment bouth sentence It's compile fine. but not when we want to enable external Interrupt.
whot is the right way or place to this void ConfigInt0 line

Leave out the void?

ConfigInt0(EXT_INT_ENABLE |FALLING_EDGE_INT | EXT_INT_PRI_5 );

This should call the function.

With the void, it is a function prototype declaration.

we have coded some interrupt is working in Mplab but it dos nog clered the bit 0 on port D
