Using : Board -Arduino Pro or Pro Mimi & Processor - ATmega328P (3.3V, 8 MHz)
Pin 3 has a grounded magnetic switch connected to it that is normally open with no magnetic field applied.
Pin 9 has an indicator LED connected.
When I add the radio code and upload it, it seems to only transmit once and that's it.
Please try to see the error(s).
first I tested my code interrupt with this code and it performs as it should.
const byte interruptPin = 3;
byte ledPin = 9;
void setup ()
{
pinMode (interruptPin, INPUT_PULLUP);
attachInterrupt (digitalPinToInterrupt(interruptPin), processChange, CHANGE );
pinMode (ledPin, OUTPUT);
digitalWrite (ledPin, LOW);
if (digitalRead(interruptPin) == HIGH)
{
digitalWrite(ledPin,HIGH);
}
} //End setup()
void loop ()
{
// do nothing
}
void processChange ()
{
delay (20);
if (digitalRead(interruptPin) == LOW)
{
digitalWrite(ledPin,LOW);
}
else
{
digitalWrite(ledPin,HIGH);
}
}Then I added the radio code as follows:
#include <RFM69.h>
#include <SPI.h>
#include <LowPower.h>
// Addresses for this node. CHANGE THESE FOR EACH NODE!
#define NETWORKID 144 // Must be the same for all nodes
#define MYNODEID 4 // My node ID
#define TONODEID 1 // Destination node ID
// RFM69 frequency, uncomment the frequency of your module:
//#define FREQUENCY RF69_433MHZ
#define FREQUENCY RF69_915MHZ
// AES encryption (or not):
#define ENCRYPT true // Set to "true" to use encryption
//#define ENCRYPT false // Set to "true" to use encryption
#define ENCRYPTKEY "TOPSECRETPASSWRD" // Use the same 16-byte key on all nodes
// Use ACKnowledge when sending messages (or not):
#define USEACK true // Request ACKs or not
//#define SERIAL true
//#define RESET true
// Create a library object for our RFM69HCW module:
RFM69 radio;

if (digitalRead(interruptPin) == HIGH)
{
digitalWrite(ledPin,HIGH);
}
// Initialize the RFM69HCW:
radio.initialize(FREQUENCY, MYNODEID, NETWORKID);
radio.setHighPower(); // Always use this for RFM69HCW
// Turn on encryption if desired:

} //End setup()
