good moorning!!!

this is my problem :

I use a input capture modul of dspic to detect edges.

my input capture configuration :

/* Input Compares */

/* Config : Timer 3 for all, idle mode ON */

IC1CON = 0x0003; // Rising edge only

IC2CON = 0x0003; // Rising edge only

IC7CON = 0x0003; // Rising edge only

IC8CON = 0x0001; // Rising and falling edge

/* Enabling Interrupts for Input Compare */

IEC0bits.IC1IE = 1;

IEC0bits.IC2IE = 1;

IEC1bits.IC7IE = 1;

IEC1bits.IC8IE = 1;

/* Interrupts priority (priority decrease IC8 to IC1) */

IPC0 = 0x0040; // set IC1 priority

IPC1 = 0x0005; // set IC2 priority

IPC4 = 0x0760; // set IC7 and IC8 priority

/* Clear interrupt flags */

IFS0bits.IC1IF = 0;

IFS0bits.IC2IF = 0;

IFS1bits.IC7IF = 0;

IFS1bits.IC8IF = 0;

and one of my interupt fonction is (the four functions are all same) :

void __attribute__ ((__no_auto_psv__ )) _IC1Interrupt (void) {

IFS0bits.IC1IF = 0; // Clear flag

TMR3 = 0;

T3CON = 0x8000; // Start Timer 3

}

I use demo board dsPICDEM2 with mplab and c30.

But when I put the chip on my own board, interrupts functions doesn't run anymore.

I checked the voltages and connectors on my board, everything is allright !

I tested capture interrupt alone (I invert an output each time I go in interrupt), and it doesn't run. So I never go in interrupt functions.

Moreover, when I test the program on the demo board (dspicdem2) it runs perfectly in debug mode, but nothing in programmer mode

Is there a specific configuration I could have miss ?

Here is the configuration of my pic :

_FOSC(CSW_FSCM_OFF & HS); // External Crystal

_FWDT(WDT_OFF); //watch dog off

_FBORPOR(MCLR_DIS & PWRT_OFF);

_FGS(CODE_PROT_OFF);

thank you for your help (and sorry for my english !).
