Hello guys
im new in arduino and i am trying to make some projects.
i use this tut :: ESP8266 Android App To Control Arduino Digital Pins and Toggle LEDs
now i want to use ESP8266 library for Arduino : GitHub - itead/ITEADLIB_Arduino_WeeESP8266: An easy-to-use Arduino ESP8266 library besed on AT firmware.
is there anyone can help me to change the normal code to codes using library?
i go this far
#include <doxygen.h>
#include "ESP8266.h"
#include <SoftwareSerial.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2); //moshakhas kardane pin haye LCD
SoftwareSerial mySerial(7, 8); // moshakhas kardane pin haye wifi
ESP8266 wifi(mySerial);
#define SSID "Arsalan Wifi" //UserName wifi
#define PASSWORD "arsalan123" //Password wifi
void setup() {
lcd.begin(20, 4);
Serial.begin(9600);
pinMode(13,OUTPUT);
digitalWrite(13,HIGH);
String IP;
Serial.print("setup begin\r\n");
lcd.print("Connecting to Wifi");
delay(3000);
Serial.print("FW Version: ");
// Serial.println(wifi.getVersion().c_str());
if (wifi.setOprToStation()) {
Serial.print("to station ok\r\n");
} else {
Serial.print("to station err\r\n");
}
if (wifi.joinAP(SSID, PASSWORD)) {
Serial.print("Join AP success\r\n");
Serial.print("IP: ");
Serial.println(wifi.getLocalIP().c_str());
IP = wifi.getLocalIP().c_str();
lcd.setCursor(0, 1);
lcd.print("Join AP success");
lcd.setCursor(0, 2);
lcd.print("IP: "+IP);
} else {
Serial.print("Join AP failure\r\n");
lcd.setCursor(0, 1);
lcd.print("Join AP failure");
lcd.setCursor(0, 2);
lcd.print("Contact Administrator");
}
if (wifi.enableMUX()) {
Serial.print("multiple ok\r\n");
} else {
Serial.print("multiple err\r\n");
}
if (wifi.startTCPServer(80)) {
Serial.print("start tcp server ok\r\n");
lcd.setCursor(0, 3);
lcd.print("Server Ready");
} else {
Serial.print("start tcp server err\r\n");
lcd.setCursor(0, 3);
lcd.print("Server Setup Fail");
}
if (wifi.setTCPServerTimeout(10)) {
Serial.print("set tcp server timout 10 seconds\r\n");
} else {
Serial.print("set tcp server timout err\r\n");
}
Serial.print("setup end\r\n");
}
but i dont know how to change this part.

sorry for my bad english,
anyone can help me please?
