/*========= Virtuino General methods

*

* void vDigitalMemoryWrite(int digitalMemoryIndex, int value) write a value to a Virtuino digital memory (digitalMemoryIndex=0..31, value range = 0 or 1)

* int vDigitalMemoryRead(int digitalMemoryIndex) read the value of a Virtuino digital memory (digitalMemoryIndex=0..31, returned value range = 0 or 1)

* void vMemoryWrite(int memoryIndex, float value); write a value to Virtuino memory (memoryIndex=0..31, value range as float value)

* float vMemoryRead(int memoryIndex); read a value of Virtuino memory (memoryIndex=0..31, returned a float value

* run(); neccesary command to communicate with Virtuino android app (on start of void loop)

* int getPinValue(int pin); read the value of a Pin. Usefull to read the value of a PWM pin

* long lastCommunicationTime; Stores the last communication with Virtuino time

// 1. On Arduino IDE software select the board NodeMCU. If the board isn't in boards list, open the boards manager, on the search line enter esp8266 and download all ESP8266 boards

// 2. Open the Virtuino library file: VirtuinoESP.h, enable the line #define NODEMCU and disable the other boards

// 3. Connect the NODEMCU ESP8266 module to usb and upload this code

#include <ESP8266WiFi.h>

#include "Virtuino_ESP_WifiServer.h"

WiFiServer server(8000); // Set Server port

Virtuino_ESP_WifiServer virtuino(&server);

//Its availavle pin in NodeMCU ESP8266 pins= D0,D1,D2,D3,D4,D5,D6,D7,D8,D9,D10

// Example variables

int storedValue=0;

//============================================================== setup

//----- NodeMCU module settings

//----- prepare GPIO2

pinMode(2, OUTPUT);

// Settings as Access point - Create a private Wifi Network. Enable the next five lines to use module as Acces point

Serial.print("Setting soft-AP ... "); // Default IP: 192.168.4.1

WiFi.mode(WIFI_AP); // Config module as Acces point only. Set WiFi.mode(WIFI_AP_STA); to config module as Acces point and station

boolean result = WiFi.softAP("Vicinity InfoIndia", "12345678"); // SSID: Vicinity India Password:12345678

if(result == true) Serial.println("Vicinity India Server Ready");

else Serial.println("Failed!");

// ---- Start the server

//============================================================== loop

// enter your loop code here.

//------ avoid to use delay() function in your code

int v=virtuino.vDigitalMemoryRead(0); // Read virtual memory 0 from Virtuino app
