// FABACADEMY2020 groupwork modifications for this Adafruit IO digiout example:
// -- added software serial for communicating with attiny412 and removed default serial support
// -- added secondary Adafruit IO channel for controlling attiny412
// -- added serial communication wit attiny142 to second adafruit IO channel
// Group: Jari, Hannu, Achille and Anssi

/********* Configuration ************/

// edit the config.h tab and enter your Adafruit IO credentials
// and any additional configuration needed for WiFi, cellular,
// or ethernet clients.
#include "config.h"
#include<SoftwareSerial.h> //Included SoftwareSerial Library
/******** Example Starts Here ***********/

// digital pin 4 on ESP8266
#define LED_PIN 4
// let's define software serial
SoftwareSerial Serialm(3,1);

// set up the 'digital' feed (button ESP in Adafruit IO UX)
AdafruitIO_Feed *digital = io.feed("digital");
//set up the 'digital2' feed (button attiny142 in Adafruit IO UX)
AdafruitIO_Feed *digital2 = io.feed("digital2");

void setup() {
  // GPIO pin is defined to be output
  pinMode(LED_PIN, OUTPUT);
  
  // start the software serial connection
  Serialm.begin(9600);

  // connect to io.adafruit.com
  Serialm.print("Connecting to Adafruit IO");
  io.connect();

  // set up a message handler for the 'digital' and 'digital2' feeds.
  // handleMessage and handlemessage2 functions (defined below)
  // will be called whenever a message is
  // received from adafruit io.
  digital->onMessage(handleMessage);
  digital2->onMessage(handleMessage2);

  // wait for a connection
  while(io.status() < AIO_CONNECTED) {
    Serialm.print(".");
    delay(500);
  }

  // we are connected
  Serialm.println();
  Serialm.println(io.statusText());
  // Adafruit IO feeds are refreshed
  digital->get();
  digital2->get();

}

void loop() {

  // io.run(); is required for all sketches.
  // it should always be present at the top of your loop
  // function. it keeps the client connected to
  // io.adafruit.com, and processes any incoming data.
  io.run();

}

// this function is called whenever an 'digital' feed message
// is received from Adafruit IO. it was attached to
// the 'digital' feed in the setup() function above.

void handleMessage(AdafruitIO_Data *data) {

  Serialm.print("ESP received <- ");

  if(data->toPinLevel() == HIGH)
    Serialm.println("HIGH");

    Serialm.println("LOW");

  digitalWrite(LED_PIN, data->toPinLevel());
}

// this function is called whenever an 'digital2' feed message
// is received from Adafruit IO. it was attached to
// the 'digital' feed in the setup() function above.

  if(data->toPinLevel() == HIGH){
    Serialm.println("HIGH2");
    // let's send 2 via serial connection to attiny412. Thiss will lit put LED on attiny412 to HIGH
    Serialm.write("2"); 
    }
