PcInt Library

This is an Arduino library to administrate and handle Pin Change Interrupts as needed to allow the Mayfly to sleep and save battery power.

This is modified from the Sodaq library to work properly with other libraries using pin change interrupts (SoftwareSerial and SDI-12 specifically.) This only makes use of PCINT0.

Examples

... TODO ... Here is a quick example to get you started

#include <Sodaq_PcInt.h>
void setup()
{
  pinMode(A0, INPUT_PULLUP);
  PcInt::attachInterrupt(A0, handleA0);
}

void loop()
{
  // ...
}

static uint8_t rain1ticks;
void handleA0()
{
  static bool rain1State;
  //rain counter 1
  if (digitalRead(A0) == LOW) {
    if (!rain1State) {
      rain1ticks++;
      rain1State = true;
    }
  } else {
    rain1State = false;
  }
}
