Hello Forum,
I have a problem with conflicting libraries. Anyone who knows how I can overcome this.
I have two interrupts; one to wake the ATMEGA328 and the other to retrieve data from a sensor register. I want to use pin 9 for interrupt. I get below error message when I run the code.
Here is the code I am using, libraries attached.
#include "PinChangeInt.h"
#include <SPI.h>
#include "AS3935n.h"
#include <avr/sleep.h>
#include<SoftwareSerial.h>
#include "<PinChangeInt.h>"

String inputString = "";
bool stringComplete = false;
char time1[30];
unsigned long beit; //Stores bytes from AS3935 registers
unsigned long strokeEnergy; //Stores stroke energy from AS3935 registers
#define ARDUINOPIN 9 // Maps to ATmega328 pin15, connected to IRQ Thunder click
void printAS3935Registers();
// Function that provides SPI transfer and is passed to
// AS3935 to be used from within library.
byte SPItransfer(byte sendByte);
// Iterrupt handler for AS3935 irqs
// and flag variable that indicates interrupt has been triggered
volatile int AS3935IrqTriggered;
void AS3935Irq()// Used when
// 1. Controller wakes up from sleep
//2. When there is lightning strike and there is lightning strike.
{
//FIRST THING AFTER WAKING UP.

detachInterrupt(ARDUINOPIN); // wakeUpNow code will not be executed. WAKE UP NOW will not be executed during normal running time
AS3935IrqTriggered = true;
}
// First parameter - SPI transfer function, second - Arduino pin used for CS
// and finally third argument - Arduino pin used for IRQ
// Library internally polls this pin when doing calibration, so being an interrupt pin
// is not a requirement
