[PIC] FFT input format for dsPIC30F

it is some years since I used this but I seem to remember copying the ADC data into the .real component and zeroing the .imag component of the input arrays

//Acquire signal from ADC pin replace real part  
	//with ADC value, set imiginary part as 0	
        for (i=0;i<NUMSAMP;i++) {
	     sigCmpx[i].real = inputSignal[i];					
	     sigCmpx[i].imag = 0;							
	}

Thanks for your reply. I have the following code, is this what you refer to?

Code:

//Acquire signal from ADC pin replace real part  
	//with ADC value, set imiginary part as 0	
        for (i=0;i<NUMSAMP;i++) {
	     sigCmpx[i].real = inputSignal[i];					
	     sigCmpx[i].imag = 0;							
	}
