I tried this Application Note - TB3263:Getting Started with ADCC for PIC18
 
For the 4th example - ADCC Spike Detection, the main.c is here:
 
uint16_t volatile errVal;

void main(void)
{
    SYSTEM_Initialize();
    
    INTERRUPT_GlobalInterruptEnable();
    INTERRUPT_PeripheralInterruptEnable();
    
    ADCC_SetADTIInterruptHandler(ThresholdISR);
    ADCC_DischargeSampleCapacitor();
    ADCC_StartConversion(channel_ANA0);


    while (1)
        {
            ;
        }
}

void ThresholdISR(void)
{
    errVal = ADCC_GetErrorCalculation();
    PIR2bits.ADTIF = 0;
}

 
when I built it, it was prompted:
"warning: implicit declaration of function 'INTERRUPT_PeripheralInterruptEnable' is invalid in C99 [-Wimplicit-function-declaration]"
 
has anyone used this function - INTERRUPT_PeripheralInterruptEnable(), should it be explicit declaration? where and how?

Hi,
 
'INTERRUPT_PeripheralInterruptEnable'  is a macro that is created by MCC,
when use of interrupts is configured in the GUI of MCC,
and the proper #include "something" is used in the main program.
 
Either you have Not shown all of your main program file,
or there is a missing include for files generated by MCC:
#include "mcc_generated_files/mcc.h"
 
If you have made changes in MCC setup, then a 'Generate' may be needed.
 
Or you may try:   INTCONbits.PEIE = 1;   // instead, if you want to diy.

Here is the whole main. I searched in MCC several times, haven't found where to set "PeripheralInterruptEnable".
Actually, there was not any place for "PeripheralInterrupt", either in "Interrupt Module" or in "Peripherals" or "Device Resources".
